Engineered industrial DC UPS systems, continuous battery backup packages, and smart battery chargers designed for critical automation, sub-stations, and telemetry networks.
Engineering Excellence Since 1994
Micro Power (manufactured by Sanstar Microsystems Pvt. Ltd.) delivers high-reliability industrial DC power backup solutions engineered to eliminate system reset, memory loss, and operational downtime caused by power grid fluctuations.
In modern industrial facilities, sub-stations, and automated processing plants, power interruptions lasting even a few milliseconds can disrupt Programmable Logic Controllers (PLCs), Remote Terminal Units (RTUs), and SCADA telemetry networks. Standard AC UPS systems add unwanted double-conversion thermal stress and mechanical changeover latency.
Our dedicated DC power backup solutions feed the DC bus directly. Designed with active power factor correction (PFC), intelligent float-boost battery chargers, and seamless diode ORing isolation, Micro Power systems deliver instant battery energy transition without voltage dips or switchover delays.
Every Micro Power backup system is assembled on a 100% anti-static shop floor at our MIDC Hingna Road facility in Nagpur, India. Component screening, automatic magnetic winding, micro-controller programming, and full-load burn-in testing under elevated temperatures guarantee international performance compliance for OEM export projects.

Frequently Asked Questions
Unlike standard commercial AC UPS units, industrial DC power backup solutions directly buffer the DC bus bar. This design eliminates double conversion losses and inverter switchover delays, delivering seamless, uninterrupted power directly to PLCs, RTUs, and critical switchgear loops during grid disturbances.
Micro Power DC UPS backup systems utilize continuous online battery float topology combined with diode ORing architecture. When the AC primary grid fails, the standby battery bank immediately supplies the load with zero millisecond transfer latency, preventing PLC reboot or communication dropouts.
Our intelligent backup charging systems feature fully customizable float and boost voltage profiles compatible with VRLA/SMF (Sealed Lead Acid), Tubular Gel, Lithium Iron Phosphate (LiFePO4), and Nickel-Cadmium (Ni-Cd) battery banks.
Yes. Our in-house R&D and sheet metal fabrication teams develop custom power backup solutions. We can adapt input voltage ranges, output DC rails (12V, 24V, 48V, 110V, 220V), enclosure dimensions, IP ratings, and alarm relay signals to meet exact technical specifications.
