Uninterupted Power Supply (UPS)
ONLINE UPS
In few cases the small switching time is usually not enough to cause computers and servers to shut down. Online UPS supplies contineous power from internal batteries, which recharge contineously from the AC source.
Thus these systems continue to supply in case of a utility failure, without time log.
To overcome there problems we DIGITECH manufacture Online UPS having fully Pulse Width Modulation (PWM) controlled and are available in Pure Sine Wave output with low harmonic distortions.

OFFLINE UPS
UPS is an alternative power supply source for electric and electronic power equipment when regular power supply source is suddenly cut off. Offline or standby UPS switches over from main to battery power during power cut off.
The battery-powered inverter of the UPS kicks into supplying power temporarily, so that systems/equipment can be shut down in an orderly manner, without damage.
We, DIGITECH have UPS of off-line topology. We use latest state of electronic topology i.e. microcontroller based circuit. Our selective models are available with communication port and remote on/off facility that enables us to operate large UPS (remote placed) from your computer room.
