ELS-1K1-CHR-V1
1120W AC/DC POWER SUPPLY AND BATTERY CHARGER (SMGK)
GENERAL INFORMATION
1120W Power Supply has the feature of working with both AC and DC voltage. It
produces multiple DC power at different voltage and current levels from AC or DC
source. If a 24V battery is connected to the DC input, it can both feed the load and
charge the battery when there is an AC input. When the AC mains is interrupted, the unit continues to feed its outputs from the battery at the DC input. It is designed to be compatible with shock, vibration, temperature, EMC / EMI and electrical fluctuations in the input line, which are in tough military standards.
