1)
Supply voltage range:
At voltages within the input voltage range, the control functions such as LEDs, monitoring functions, relay contacts, etc. function as nor-
mal. Within the input voltage range the device can either be in power supply mode or buffer mode.
2)
Normal operating voltage range:
The normal operating voltage range describes the supply voltage that supports the full functionality of the buffer module (including
charging) without entering buffer mode.
