Double Conversion Online UPS

The GEESYS 3/3 UPS includes the 10 KVA to 200 KVA (3 phase input, 3 phase output) Double Conversion On- Line UPS with an isolation transformer at Output. The Load is supplied continuously by the inverter with clean, stabilized and regulated sine wave output power. We are among the reliable Manufactures, Suppliers and Exporters of Double Conversion Online UPS.

Input & Output filters increase the immunity of load from power disturbances and surges. GIGA Line is useful for mission critical applications like IT, Call Centres, Hospitals, Industrial Automation, etc. Thanks to state-of-the-art microprocessor / DSP based outstanding advanced technology design. GIGA Line is supplied with software which can be used for monitoring various parameters of the UPS and also can be useful for remote monitoring / control on the web by adding SNMP Card. This Double Conversion Online UPS has an isolated output. Also, for the purpose of efficient consumption of power, this Double Conversion Online UPS comes with an advanced battery management system.
