Get Over The Power Problems

Recent findings reveal that power problems are the greatest threat to your critical equipments’ uptime. Business depends on continuous quality power to avoid revenue losses resulting from system failures. The power problems that endanger your critical systems are sags, surges, noise, brown outs, black outs etc. Requirements of quality power protection are :

* To provide a clean and stable supply which is isolated from contaminated utility mains.

* To provide continuous AC sinewave power from the charged batteries in case of extreme brown outs or black outs.

* To facilitate system expansion by providing features such as Extended back up time, Hand in hand operation for extremely low input supply, Quick recharge facility which enables to charge the batteries in minimum time.

* To improve overall system reliability and uptime by providing auto switch over to AC reserve or Bypass supply.

All the above features are packaged in Crotech AU3000 Series which is compact, user friendly and simple to install.
