PLC & HMI Control Cabinets
Prevents loss of volatile memory, program execution errors, and unexpected shutdown of automated manufacturing lines during brief voltage dips.
Industrial Grade DC Power Backup
Micro Power (Sanstar Microsystems Pvt. Ltd.) manufactures specialized industrial-grade DC UPS systems engineered to safeguard critical control automation equipment—including PLCs, HMIs, Industrial PCs, telemetry units, and data loggers—against mains voltage dips, brownouts, and sudden blackouts.
Traditional AC UPS units suffer from double-conversion efficiency losses and potential switchover glitches. Micro Power DC UPS systems connect directly to the DC bus bar, providing instantaneous battery takeover during power outages with zero millisecond transfer delay.
Built with robust steel housing and high-efficiency power convertors, each unit incorporates internal battery charge regulation, deep discharge protection, and comprehensive LED diagnostic indicators with potential-free alarm contacts for easy integration into SCADA and PLC control systems.

Frequently Asked Questions
A DC UPS directly provides direct current (12V, 24V, or 48V DC) to the system bus without converting DC power back into AC. This eliminates double conversion energy loss, reduces heat inside control panels, provides zero millisecond transfer latency, and increases total system reliability.
Our standard units are optimized for Sealed Lead Acid (VRLA / AGM) battery banks. Customized charging profiles for Lithium-ion (LiFePO4) chemistries are available upon request for OEM projects.
