Switching Mode Power Supply Manufacturer
Micro Power is the brand of Sanstar Microsystems Pvt. Ltd., an Indian manufacturer of switch mode power supplies (SMPS), DIN rail power supplies, DC UPS systems, DC-DC converters and industrial battery chargers. A power supply is the heart of every panel we serve — if it fails, the CCTV network, fire alarm loop or production line stops. That single responsibility shapes how we specify components, derate designs and test every unit.
Design, PCB assembly, magnetics, potting, burn-in and final load testing are handled in-house at our MIDC Hingna Road facility in Nagpur, so engineering changes reach production quickly and traceability stays intact. Our board carries more than three decades of experience in manufacturing diverse electronic products, and our R&D group pairs young engineers with long-serving power-supply specialists.

Featured Product
One compact unit that powers the load and maintains the standby battery: ideal for fire alarm panels, access control and security cabinets where a UL-recognised, space-saving solution is specified.
A single-board architecture removes the separate charger module, cuts panel wiring and lowers the number of failure points. Automatic changeover keeps the DC bus live during mains loss, while battery-reverse and deep-discharge protection extend standby battery life.
Our application engineers help match battery Ah capacity, backup time and cable drop before you finalise the panel drawing.
Our Products
We design dedicated platforms for electronic security & surveillance and for industrial automation, because a fire panel, a PoE backbone and a PLC cabinet each stress a power supply differently.
Micro Power standard SMPS, battery chargers, chargers with on-board battery provision, isolated DC-DC converters and Li-ion chargers — plus a full DIN rail range for fire panel applications, PoE switches, DVR/NVR racks and access control doors.
One of India's established industrial battery charger manufacturers: panel-mount SMPS, DIN rail SMPS, DC UPS, diode ORing / redundancy modules, AMF and VCB panel chargers, and DC power packs with integral battery backup for unattended installations.
Product Categories
Browse the range by mounting style, certification and backup architecture.
Compact 12V, 24V and 48V DIN rail SMPS with wide AC input, active PFC options and tool-free rail mounting for automation and fire panels.
Panel-mount AC to DC converters plus isolated DC-DC converters rated for the shock, vibration and wide input swings of railway and telecom cabinets.
Float-boost and constant-current chargers for diesel generator, fire engine, AMF, VCB, substation and railway battery banks, with adjustable set points.
Seamless DC backup for controllers, network gear and alarm loops — no inverter stage, no changeover glitch, with battery health supervision.
Enclosed DC power packs with provision to house the battery inside — one part number for the supply, charger, battery space and protections.
Diode ORing redundancy modules for N+1 architectures so a single power supply fault never takes the DC bus down.
Our Specialities
Experience on the shop floor, expertise in power electronics and accountability after delivery.
We support customers through emergencies and aim to exceed expectations on service turnaround, replacement units and application guidance.
Three decades of continuous SMPS development give us tested reference designs for security, automation, DG and railway duty cycles.
A mixed team of young and veteran engineers moves designs to the next technology level fast — from Li-ion charging to higher-density magnetics.
Assembly, potting, burn-in and final testing happen under one roof with a 100% anti-static shop floor and full batch traceability.
BIS approved and CE approved DIN rail families plus a UL certified 60W SMPS cum charger, backed by documented type-test results.
Output voltage, mechanical footprint, alarm contacts, communication and labelling adapted to your panel and market requirements.
A dedicated raw-material testing team ensures only fully compliant components reach the shop floor — the root of long field life.
Dealers and distributors across India plus an active technical support desk keep lead times short and downtime shorter.
Customised Solutions
Recent build-to-specification projects delivered for Indian and export OEMs.
Two independent chargers with ORing on the DC bus: either unit can be serviced live without interrupting the protection or control supply.
Hot-standby charging for start batteries in data-centre generator rooms, with alarm contacts wired to the BMS for early fault reporting.
Low-ripple 24V supplies sized for inrush from I/O cards, contactors and HMIs, with remote sense and adjustable output for long cable runs.
Industries We Cater
From city surveillance networks to generator rooms and railway equipment cabinets, Micro Power products are selected where continuous DC availability is non-negotiable. Our team will help you confirm output voltage, holdup time, derating at ambient temperature and enclosure protection before you release the purchase specification.
Analogue and IP CCTV, PoE-enabled cameras, access control, DVR/NVR racks and fire alarm panels — served by SMPS battery chargers, 24VAC PTZ supplies and DC backup units.
PLC control panels, AMF and VCB panels, textile, plastic moulding and food processing machines, energy monitoring and transmission & distribution projects — with panel-mount and DIN rail SMPS, DC UPS, diode ORing and battery chargers.
Isolated DC-DC converters and chargers for signalling, trackside and telecom shelters, where wide input range and surge immunity decide service life.
Buyer FAQs
We manufacture BIS approved DIN rail mounting power supplies, CE approved DIN rail power supplies and a UL certified 60W SMPS cum battery charger. Every unit is burn-in and load tested before dispatch from our Nagpur plant, and test documentation can be shared with your quality department.
Yes. Our in-house R&D team develops build-to-specification solutions such as dual redundant battery charging systems, redundant chargers for data-centre diesel generators, SMPS for PLC panels and DC-DC converters for railway and telecom equipment — from specification review and prototype to type-test documentation and series production.
Choose a DC UPS when the panel already has a battery bank and you need seamless changeover with battery supervision. Choose a DC power pack with battery backup when you want the supply, charger, protections and battery space inside a single enclosure — typically for remote or unattended installations.
Standard platforms cover 12V, 24V and 48V DC in panel-mount and DIN rail formats, along with 24VAC supplies for PTZ cameras and isolated DC-DC converters. Redundancy modules allow N+1 configurations for critical DC buses.
