These UPS systems have a unique feature of re-transferring load automatically back to inverter as long as inverter is healthy and the load is within the capacity of the UPS.

This feature is very helpful for starting of loads, which draw starting in-rush current more than capacity of the UPS. The UPS goes to bypass on sensing over load and comes back on inverter supply automatically once the load current is settled to normal level.

In addition to static switch, manual bypass switch is also provided for easy maintenance.

The power electronics is in the form of draw out modules having fork connectors for power and pluggable connectors for control. This ensures easy maintenance, low MTTR and compact size.

The UPS can operate in the line-interactive mode simply by changing a jumper. The efficiency in this mode is more than 96% leading to a big energy saving in applications where UPS is used as standby power source .

UPS-Management software is a client /server application for local, global networks and also for single workstation. The server module the UPS Management Software is called UPSMAN, which communicates with the UPS in RS232 via cable, or through the network, by a SNMP adapter.

When the system starts up, UPSMAN automatically begins to collect all the information that the UPS makes available, and prepares to react to eventual UPS events according to the customer's settings.

All the available information is distributed on the network in various forms, among which: HTTP through the integrated web server ,SNMP with the special agent and another customized protocol to communicate with monitoring programme.

UPSMON and JAVAMON are used to maintain and monitor the UPS from any computer connected to the network and with every operating system that supports JAVA. It is possible to check the status of the UPS, carry out different tests or visualize graphs of the measurements collected. It is also possible to constantly monitor the files of events and measurements that UPSMAN updates in real time.
