Benson Services

Our wide series of online UPS system at Benson is specifically designed to protect computers and other critical equipments against all possible power problems. We offer total excellence through process of continued research and development.

Microprocessor Control
Dual microprocessors are used for control and communication functions. The microprocessor controls various operations of input and output parameters. Also the processor monitors various operating values and sounds an audible alarm wherever a fault occurs. The display shows the cause of the alarm, in addition to the other series of measurements at that point of time, making the UPS more user-friendly.

Monitoring And Display Functions
Allows monitoring of all important input and output parameters. All system options, battery voltage, battery-charging and discharging-currents, output-overload and after-alarm messages and settings are displayed on the front LCD panel. This option is available either on 4-line or 2-line LCD front panel. Optionally, an LED mimic panel displaying mains-on, charge-on, load-on inverter, battery-Low trip, inverter-on, inverter trip, etc., are also available.
