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.
