Explore our certified range of 12V, 24V, and 48V DC power supplies, DIN-rail SMPS, battery chargers, and DC-DC converters engineered for mission-critical deployments.
A comprehensive examination of Switch Mode Power Supply (SMPS) topology, zero-transfer time DC UPS integration, and environmental hardening for coastal industrial zones.
Mumbai's industrial corridors—such as MIDC Taloja, Thane-Belapur, and Rabale—frequently experience severe brownouts, voltage sags, and high-energy transients caused by nearby heavy machinery switching. Our 12V battery backup systems are built with advanced wide-range Active PFC circuitry, allowing stable DC output regulation even when grid voltage fluctuates between 90 VAC and 290 VAC.
Unlike traditional AC UPS systems that suffer from 10–20ms transfer delays during power outages, our integrated 12V DC UPS topology connects the load directly to the DC bus. When mains supply drops, the battery instantly delivers current without a millisecond of interruption, preventing PLC system resets, CCTV frame dropouts, or data corruption in critical automation controllers.
Improper charging shortens Sealed Lead-Acid (SLA) and LiFePO4 battery lifespan significantly under elevated ambient temperatures. Our power supplies feature automatic temperature-compensated 3-stage charging (Bulk, Absorption, Float) with built-in Low Voltage Disconnect (LVD) protection to prevent deep battery discharge and irreversible sulfation.

Tailored 12V battery backup power supply solutions addressing the distinct operational and environmental demands of Mumbai's key infrastructure sectors.
In maritime logistics zones like Jawaharlal Nehru Port Trust (JNPT) and coastal container freight stations (CFS) across Navi Mumbai, electronics face extreme saline air corrosion. Our 12V power supply units feature double-layered conformal acrylic coating on all surface-mount components, protecting harbor gateway access control, barrier gates, and maritime security surveillance panels against saltwater oxidation.
As Asia’s rapidly growing data hub, Navi Mumbai (Airoli, Millennium Business Park, Mahape) houses high-density server farms. Our 12V and 24V DIN-rail backup SMPS feed peripheral environmental monitoring systems (EMS), biometric reader access arrays, and rack-level fire suppression actuators where uninterrupted zero-transfer standby power is mandatory.
Powering thousands of urban traffic surveillance cameras and speed detection nodes for BMC and Mumbai Traffic Police. Given Mumbai's torrential monsoon season, outdoor junction boxes rely on our ultra-compact 12V 10A aluminum-cased SMPS with integrated backup battery charging to guarantee continuous recording during street-level grid outages.
Heavy manufacturing units in Thane-Belapur Road, Dombivli, and Taloja MIDC rely on PLCs, HMIs, and solenoid valves. Power spikes during peak tariff switching can reset vulnerable control loops. Micro Power’s industrial DIN rail DC UPS buffers these transients, keeping production lines operational without unprogrammed down-times.
Mumbai's suburban rail network—one of the busiest worldwide—requires absolute reliability for trackside signaling and VCB switchgear tripping units. Our custom 12V/24V power packs provide float-boost battery charging engineered to withstand harsh vibration and heavy electrical noise near traction lines.
How Micro Power's 30 years of localized R&D counters monsoon humidity, high ambient temperatures, and urban space constraints.
Mumbai records relative humidity exceeding 90% from June through September. Standard commercial power supplies fail due to atmospheric tracking and component flashovers. Our units undergo specialized vacuum impregnation of transformers and conformal coating to eliminate moisture-induced short circuits.
With real estate values in Mumbai among the highest globally, control panels in commercial buildings (BKC, Lower Parel) must minimize footprint. Our slimline 30mm DIN-rail profiles reduce cabinet space requirements by up to 40% while preserving thermal dissipation performance.
Enclosed panel temperatures inside unconditioned industrial plant rooms in Bhiwandi or Kurla routinely exceed 50°C. We design SMPS topologies using 105°C-rated long-life Japanese electrolytic capacitors, ensuring reliable operation without severe power derating.
As Mumbai enterprises transition to Lithium Iron Phosphate (LiFePO4) batteries for faster recharge rates and longer cycle lives, our power supply chargers feature custom-selectable charging profiles tailored to either SLA or Lithium battery chemistries.

Direct technical clarity for electrical engineers, panel builders, and procurement officers sourcing power backup systems in Maharashtra.
Our industrial SMPS models supplied across Mumbai and coastal Maharashtra are manufactured with double-pass acrylic conformal coating on all circuit board assemblies. This protective barrier seals sensitive electronic tracks against moisture ingress, salt haze, and airborne corrosive contaminants common in dockyards and coastal industrial parks.
A standard 12V SMPS converts AC grid power directly into regulated 12V DC to power your equipment. If grid power drops, output falls to zero. A 12V DC UPS incorporates an integrated battery charger, automatic load-transfer switch, and Low Voltage Disconnect (LVD). It simultaneously powers the DC load while keeping a backup battery fully charged, switching to battery power with zero millisecond disruption during outages.
Yes. Our DIN-rail power supplies, standard AC-to-DC converters, and battery chargers carry Bureau of Indian Standards (BIS) approval under IS 13252. Furthermore, we offer CE-marked variants for export projects and UL-certified models (such as our 60W SMPS cum battery charger range).
With our primary manufacturing facility situated at MIDC Hingna Zone in Nagpur, we maintain rapid logistics pipelines across Maharashtra. Standard catalog models are dispatched via express freight to Mumbai, Thane, Navi Mumbai, and Pune industrial zones within 24 to 48 hours.
Absolutely. Sanstar Microsystems specializes in OEM custom engineering. We regularly design tailored output voltages (e.g., 13.8V, 27.6V, 54.4V), dual-redundant battery charger topologies with diode OR-ing modules, specialized fault alarm contacts, and custom enclosure dimensions matching your exact panel design.
During extended power outages, connected loads continuously drain the standby battery. If deep discharge drops battery cell voltage below critical thresholds, permanent battery degradation occurs. Our automated LVD circuit monitors battery discharge voltage and safely disconnects the load when the battery hits 10.5V (for 12V systems), preserving battery health for thousands of future discharge cycles.
