Explore our top-tier CE, BIS, and UL compliant switching mode power supplies engineered for zero-downtime surveillance networks, automation panels, and industrial equipment.
Founded in 1994, Sanstar Microsystems Pvt. Ltd. (Micro Power) has established itself as an authoritative pioneer in high-reliability Switch Mode Power Supply (SMPS) design, industrial battery chargers, and DC UPS backup systems. Located in the EL-15 Electronic Zone, MIDC Hingna Road, Nagpur, India, our specialized manufacturing plant drives power electronic innovation for high-stress security, telemetry, railway, and automation infrastructure worldwide.
Modern surveillance networks cannot tolerate voltage sag, high ripple noise, or thermal shutdown. A failure in the CCTV power supply blinds the entire security apparatus. Operating on this critical mandate, our manufacturing methodology integrates strict quality control loops, robust circuit design, and certified component selection, guaranteeing continuous uninterrupted power delivery for critical surveillance and automation nodes.
Every single power unit passing through our assembly lines undergoes high-temperature full-load burn-in testing and high-voltage breakdown dielectric checks, eliminating infant mortality failures prior to field deployment.
Designed specifically for harsh grid conditions, our SMPS topology accommodates extreme voltage fluctuations ranging from 90V AC up to 290V AC, preventing component stress during severe brownouts or voltage spikes.
Our dedicated R&D lab creates bespoke mechanical form factors, multi-channel output voltages, battery charging curves (Lead-Acid & LiFePO4), and potential-free relay alarm contacts tailored to precise OEM client specs.
Micro Power operates a 100% anti-static (ESD-safe) assembly floor, backed by a highly skilled, female-dominated precision production and quality testing team. From magnetic coil winding to automated SMT inspection, our production standard ensures strict conformity with global standards including CE (LVD/EMC), BIS (IS 13252), and UL certifications.
Architecting power delivery networks for multi-camera video surveillance systems presents complex electrical engineering challenges. Unlike static resistive loads, modern IP cameras featuring long-range infrared (IR) illuminators, pan-tilt-zoom (PTZ) motors, and heater-blower enclosures exhibit highly dynamic current demands. Selecting an uncertified or under-engineered CCTV power supply introduces significant field risks: excessive ripple voltage, line drop over long distances, thermal runaway, and electromagnetic interference (EMI) that degrades video signal integrity.
Analogue High Definition (AHD, TVI, CVI) and high-bitrate 4K IP cameras utilize sensitive image sensors (CMOS/CCD). High ripple voltage in standard power supplies generates horizontal rolling lines, video hum bars, and signal loss. Micro Power CE-certified CCTV power supplies incorporate multi-stage LC output filters and ultra-low Equivalent Series Resistance (ESR) 105°C-rated electrolytic capacitors. This topology restricts peak-to-peak ripple noise to under 50mVp-p, preserving crisp pixel resolution and dynamic range across low-light camera operation.
In large-scale commercial deployments, power lines often stretch 100 to 250 meters from the central power enclosure to perimeter cameras. According to Ohm's Law ($V_{drop} = I \times R$), a standard 12V DC output degrades below the camera's minimum operating voltage threshold (typically 10.8V DC) when IR illuminators activate at dusk. Our CCTV power supply series features adjustable output voltage trimmers (up to 13.8V DC - 14.5V DC) or individual channel output boost switches, effectively compensating for line resistance losses without over-stressing camera voltage regulators.
Continuous thermal stress is the primary driver of electrolytic capacitor degradation and switching MOSFET failure in enclosed power supplies. Micro Power industrial DIN Rail and metal-case units implement Active Power Factor Correction (PFC > 0.95), optimizing real power efficiency up to 92%. Our extruded aluminum chassis design utilizes natural convection cooling without mechanical fans, eliminating fan failure risks in dusty or chemical-laden industrial ambient environments.

As security networks converge with Smart City IoT platforms, edge AI computing, and industrial automation, power infrastructure requirements are undergoing a fundamental paradigm shift. Procurement directors and system integrators must align their sourcing strategies with four primary technology trends shaping the next decade of power engineering.
Traditional setups reliant on external AC UPS backup suffer from dual energy conversion losses (DC to AC inside the UPS, and AC to DC inside the camera supply). Sourcing trends demonstrate a massive shift toward Integrated DC UPS Power Packs. By connecting battery banks directly to the DC bus via intelligent float/boost charging circuits, overall power backup efficiency rises by up to 25%, while reducing cabinet thermal load and physical footprint.
Space constraints in outdoor NEMA/IP66 pole enclosures demand ultra-compact power supplies. The adoption of Gallium Nitride (GaN) switching transistors enables higher switching frequencies (up to 500 kHz) with minimal heat dissipation. This allows factories to manufacture ultra-slim 30mm DIN Rail units delivering up to 480W, drastically reducing panel enclosure volume.
Enterprise buyers are transitioning from passive power supplies to Smart Managed Power Units featuring Modbus RTU RS485 or SNMP interface protocols. Real-time telemetry monitoring of output current draw, internal operating temperature, battery health status, and input voltage spikes enables predictive maintenance, preventing unexpected system outages before they occur.
Environmental directives and operational longevity demands are pushing suppliers away from conventional sealed lead-acid (SLA) batteries toward Lithium Iron Phosphate (LiFePO4) chemistry. Modern industrial power supplies must integrate dedicated 2-stage and 3-stage CC/CV charging algorithms designed to optimize LiFePO4 cell life over 3,000+ charge cycles.
When selecting a CE-certified CCTV power factory or supplier, procurement teams must look beyond initial unit costs. Under-rated power supplies lead to premature field failure, costly technician call-outs, brand reputation damage, and liability risks. We recommend evaluating potential manufacturing partners against the following technical criteria:
Ensure CE markings include valid LVD (EN 62368-1 / EN 60950-1) and EMC (EN 55032 / EN 55035) test reports from accredited third-party labs, accompanied by BIS (IS 13252) registration for Indian import market compliance.
Inspect the supplier's thermal derating documentation. High-quality industrial power supplies maintain 100% full-load output up to 50°C ambient temperature, whereas low-grade commercial units derate heavily above 40°C.
Verify Mean Time Between Failures (MTBF > 100,000 hours per MIL-HDBK-217F standard) and confirm that critical components (MOSFETs, ICs, electrolytic capacitors) are sourced from tier-1 global semiconductor vendors.
Confirm individual output port PTC resettable fuse protection or electronic current limiting. This prevents a single shorted camera cable from taking down the remaining cameras on the power bus.
Audit the supplier's quality control infrastructure: demand confirmation of automated optical inspection (AOI), 100% high-voltage flash testing, and computerized full-load burn-in tracking.
Assess the factory's R&D flexibility for custom output voltages, specialized metal enclosure punch-outs, wire harness pre-assemblies, and OEM branding labels.
For international deployments, mandatory compliance includes CE Certification encompassing the Low Voltage Directive (LVD EN 62368-1 for IT & AV Equipment) and Electromagnetic Compatibility Directive (EMC EN 55032/EN 55035 for emissions and immunity). For projects in India, BIS Approval (IS 13252) is legally required. Industrial control panel integration frequently specifies UL508 standards. Micro Power supplies carry certified test documentation for these standards.
In industrial zones or developing grid infrastructure, AC line voltages routinely experience extreme voltage sags (brownouts down to 100V) or spikes (up to 270V+ due to inductive load switching). Standard power supplies fail or shut down under these conditions. A wide input range of 90V to 290V AC ensures continuous DC output voltage regulation, preventing camera resets, loss of recording, and component burnout.
A standard SMPS converts AC input to regulated DC output. A DC UPS integrates switching power conversion with continuous battery backup pathways, instantly switching to battery power without any millisecond transfer delay during AC failure. A Smart Battery Charger is specifically optimized with controlled float/boost charging stages to maintain lead-acid or lithium battery banks while feeding auxiliary loads, ideal for fire panels and diesel generators.
Excessive DC ripple voltage (> 100mV p-p) introduces high-frequency noise into the camera's video processing stage. This results in visual artifacts, rolling horizontal bands, loss of night-vision clarity, and false motion-detection alarms on NVRs. Micro Power CCTV power supplies maintain ripple noise below 50mV p-p using custom LC output filtering networks.
Yes. Our in-house R&D team regularly collaborates with OEM partners to customize output voltage ratings (e.g., 5V, 12V, 24V, 48V, 72V, 110V), dual redundant charging schemes, form-factor mounting brackets (DIN Rail vs Rackmount vs Wall-mount), custom terminal blocks, potential-free relay alarm outputs, and OEM private branding.
Traditional multi-channel power supplies utilize a single glass fuse. If one camera line short-circuits due to moisture or cable damage, the main fuse blows, blinding all connected cameras. Individual PTC resettable fuses automatically isolate only the shorted camera branch. Once the line fault is cleared, the PTC automatically resets, restoring power without requiring manual fuse replacement.
