Mpt Series Line Interactive Ups

MPT Series Line Interactive UPS

The MPT Series UPS range is specially designed to provide clean power to sensitive electronic systems. It has built- in EMI filter and a special fast-sensing circuit for switching over to battery operation in case of unhealthy mains input.

A wide range of mains input voltage variation is corrected without requiring changeover to batteries to enhance battery life. The UPS output is a stepped approximation to Sine wave. PWM thereby maintaining UPS output voltage within safe limits. A piezzo-buzzer alarm and various visual indications are provided for operator convenient Output overload and short-circuit protection is provided by electronic current- limiting and fuse. Change over from battery to mains operations is internally delayed to provide mains stabilization. A dual rate CV/CC charger charges SMF as well as higher AH automotive batteries.
