Uni-Tec On Line Ups

Applications:
	• Computers • Medical equipment • Communication equipment • General & critical laboratory equipment • Process Plants • Sensitive electronic equipment and devices


Power packed features:
	• IGBT based high frequency PWM Inverter • Wide input range • Pure sine wave • Protection from spikes, surges, RFI, EMI • Constant Voltage and Frequency • Extended backup time • Reliable double conversion technology • Soft start facility • Clean computer Grade power to critical load • Generator compatible • High crest factor • Low Harmonic distortion • Static Bypass witch

Reliable Double Conversion Technology
The double conversion technology is proven, efficient, and reliable and provides clean power to critical load. The load is completely protected against spikes, surges, brownouts and power failures.

High Frequency PWM Inverter
High frequency PWM Technology using IGBT/MOSFET provides high efficiency, low noise and faster transient response.

Computer grade Line Conditioning with Isolation
Superior full time isolation is built into all Uni-Tec UPS systems. Output is fully isolated by double conversion and isolation transformer. No need to put extra isolation transformer externally.
