Brand:
DS-E33 LF 10-400KVA
Perfect UPS system protection functionality:
• Inverter output short circuit protection
• High voltage utility protection
• UPS input high and low voltage protection
• Battery polarity inverse connection protection
• Over temperature protection (rectifier, inverter, static bypass)
• Overload protection
• Battery over charge protection
• Over current protection (rectifier, inverter)
• Parallel wiring fault protection
• Wrong phase sequence, phase lost protection
• Mishandle manual maintenance switch protection
Store capacity for 1000 items of historical record:
Records status information, parameter abnormalities, fault alarms, so as to analyze equipment failure.
ECO function (bypass preference, project mode):
When the utility is comparatively stable (input voltage ±10%, frequency ±3%), ECO function could be started under project mode, followed by the UPS running efficiency reaching over 98%.
Double DSP digital control:
• Higher speed running, more precise
• Adopts double DSP chip dealing with rectifier and inverter
• Avoid the inherent parameter drift
• Strong systematic function, perfect protection.
