from 100Vdc (min) to 145Vdc (max), with modem power supply.
The APS is isolated from the measurements voltages (2kV of isolation).
Non isolated APS:
This auxiliary power supply is a single phase supply voltage with no isolation with the other meter functions.
The HV or DC meter shall be powered by the auxiliary power supply or by the main power supply.
When the two power supplies are present, the meter is powered by the highest rectified voltage.
It withstands the following AC and DC voltage levels:
from 48 Vac (min) to 100Vac without modem power supply
from 100Vac (min) to 288Vac (max), with modem power supply
from 60Vdc (min) to 100Vdc without modem power supply,
The minimum voltage for starting the meter is 60Vdc
The minimum voltage to keep the meter powered is 48Vdc
from 100Vdc (min) to 340Vdc (max), with modem power supply.
