EH9115 Series 1 Phase Low frequency UPS 2-15KVA


It is suitable in industrial equipment and instruments,armarium,computer network,elevator and the overall regulated power supply in small enterprise.Servers, Data centers,  Sensitive electronic equipment, Telecom...

Main Features:

 reliable, filtered, stabilized and regulated sine wave output (double conversion on-line technology) with filters for atmospheric disturbance suppression

 high reliability: full microprocessor control with no-break static and manual by-pass

 high level diagnostics: states, measurements and alarms - available from the built-in LCD

 power factor correction with sinusoidal input to ensure a low impact on the mains supply (UPS input power factor, close to 1) for the single-phase/single-phase series

 very low noise level <40dB(A)

 low power consumption (“Economy Mode”, Smart Active Mode, and Standby/Off Mode to increase efficiency up to 98%)

 simple to install:

 easy to position (integrated castors)

 built-in automatic and manual battery test feature

 auto restart on mains return (programmable - software or from the front panel)

 back feed protection as standard: to avoid energy feeding back into the mains supply

 integrated automatic and manual by-pass.
