Precision Engineering Since 1994
Micro Power’s standard AC to DC power supply series provides an economical yet uncompromising solution for global system integrators and panel builders. Engineered by Sanstar Microsystems Pvt. Ltd. in Nagpur, India, these industrial switching mode power supplies (SMPS) convert wide-range AC mains into stable DC power spanning from 12VDC, 24VDC up to high-voltage 110VDC platforms.
Whether integrated into PLC automation cabinets, motor control centers (MCC), process equipment, or electrical switchgears, every unit is constructed with high MTBF components, thermal stress protection, and low ripple noise topology to guarantee long-term field reliability under severe industrial grid fluctuations.
With over 30 years of specialized power electronics R&D, Micro Power ensures every AC-DC converter undergoes 100% full-load burn-in screening before dispatch. Our in-house magnetics winding, potting, and automated testing guarantee full batch traceability for critical OEM projects.
