Explore our certified range of switching power supplies, surge-resilient converters, and battery charging solutions designed for harsh electrical environments.
Manufactured under the flagship corporate identity of Sanstar Microsystems Pvt. Ltd. in Nagpur, India, Micro Power stands as a pioneer in heavy-duty power electronics, high-grade Surge Protective Devices (SPDs), Switch Mode Power Supplies (SMPS), DC UPS systems, and battery chargers. Established in 1994, our organization has dedicated over three decades to building electrical protection systems that serve as the indestructible core of security networks, telecommunications infrastructure, railway signalling, and automated manufacturing lines worldwide.
In power conversion and surge suppression, standard off-the-shelf components often fail when exposed to volatile grid conditions, high-energy lightning transients, or severe electro-magnetic interference (EMI). Micro Power mitigates these vulnerabilities through in-house magnetics engineering, proprietary thermal management topologies, and an ultra-wide AC input operating window (90V – 290V AC). Every single batch produced on our static-free assembly line undergoes 100% high-voltage isolation screening and full-load extended burn-in testing prior to global dispatch.
Engineered with multi-stage Metal Oxide Varistors (MOVs) and Gas Discharge Tubes (GDTs) capable of withstanding voltage surges up to 6kV/3kA, tolerating unconditioned grids ranging from 90V to 290V AC continuously.
From transformer winding and thermal boundary modeling to custom PCB routing and firmware development for smart chargers, our R&D team executes 100% of engineering in-house.
Every product line is subjected to high-pot dielectric withstand tests, elevated ambient dynamic thermal stress, and 100% automated full-load burn-in screening to achieve near-zero field failure rates.
Transient overvoltages—caused by indirect atmospheric lightning strikes, high-frequency inductive load switching, utility grid manipulation, or power factor correction capacitor switching—pose a severe threat to semiconductor-dense industrial electronics. A single microsecond pulse exceeding component breakdown voltages can cause immediate insulation puncture, catastrophic junction failure, or latent degradation that compromises system MTBF (Mean Time Between Failures).
Modern industrial automation and security panels demand multi-layered surge defense. Micro Power’s specialized OEM/ODM surge protection modules and SMPS front-ends employ a coordinated hybrid mitigation topology combining three complementary protection stages:
Metal Oxide Varistors degrade over time due to accumulated transient absorbances, leading to elevated leakage currents. If left unchecked, continuous leakage under nominal AC grid voltages induces thermal runaway, posing fire hazards inside control cabinets. Micro Power surge protective modules integrate Thermally Protected Varistors (TPOVs) equipped with mechanical internal disconnections and visual status telemetry flags. Upon thermal threshold breach, the internal spring mechanism physically isolates the degraded MOV element, ensuring the system remains safely protected or signaled without shutting down critical load pathways.

Insights for engineering procurement leaders, system integrators, and OEM purchasers preparing for next-generation grid dynamics and global compliance mandates.
Procurement teams are shifting away from passive surge suppressors toward intelligent monitoring units. Future-ready control panels require surge protectors fitted with potential-free relay contacts or RS-485 Modbus communications. These units track real-time transient hit counts, record residual MOV lifespan, and alert maintenance centers prior to module failure, significantly eliminating unpredicted field downtime.
The convergence of industrial power supply architecture with surge protection relies heavily on Gallium Nitride (GaN) and Silicon Carbide (SiC) semiconductors. These materials allow higher switching frequencies, smaller magnetic footprints, reduced heat generation, and superior tolerance to high dV/dt transients, making ultra-compact 30mm slim DIN-rail form factors the new global baseline.
As industrial sites integrate distributed solar PV, battery energy storage systems (BESS), and EV fast-charging hubs, localized grid power quality deteriorates. Supply chain buyers are enforcing strict mandates for power supplies capable of handling extreme voltage swings (up to 300V AC transient spikes) without tripping or output ripple degradation.
Global exporters require single-part-number power units carrying multi-region regulatory approvals. B2B procurement managers prioritize OEM vendors capable of providing pre-certified BIS (IS 13252), CE (EMC Directive 2014/30/EU), UL508, and FCC documentation to streamline global export logistics without requiring re-certification at destination ports.
Providing ripple-free 12V DC, 24V AC, and 48V PoE power to remote PTZ cameras, highway monitoring networks, and enterprise NVR servers operating under extreme lightning exposure.

DIN-rail mounted, surge-protected SMPS powering complex PLC racks, HMI touchscreens, I/O modules, and servo drive controllers in high-noise factory environments.
Automatic Float/Boost battery chargers engineered specifically to maintain engine-starter batteries in critical healthcare, data center, and commercial facility backup generators.
High-voltage isolated battery chargers and DC power packs supplying reliable trip-circuit voltage to Vacuum Circuit Breakers (VCBs) and utility distribution substations.
Galvanically isolated DC-DC converters and rugged power units compliant with railway rolling stock standards, resisting continuous vibration, shock, and line surges.
Our engineering team accommodates fully customized DC output voltage rails, unique multi-channel power distribution, custom thermal heatsink envelopes, custom DIN-rail or wall-mount enclosure chassis, potential-free fault output relay logic, dynamic battery charging profiles (Lead-Acid, LiFePO4, Li-Ion), and custom OEM brand labeling.
Our units feature an active wide-input topology (90V – 290V AC continuous capability) combined with heavy-duty input stage filter inductors, high-joule metal oxide varistors, and integrated brown-out recovery circuitry. This prevents power supply rebooting or component destruction during severe utility voltage sags and line spikes.
Micro Power products are certified across multiple global frameworks, including BIS (Bureau of Indian Standards IS 13252), CE compliance under the Low Voltage and EMC Directives, UL certification on designated 60W battery charger lines, and ISO 9001 quality management compliance across all manufacturing stages.
