EIM3.1 technical specifications
Category Specification
Frame ground
Voltage withstand: ±36 V DC to the power supply positive (terminal 1)
Voltage withstand: ±36 V DC to the power supply negative (terminal 2)
Auxiliary power supply
Input voltage: 12 or 24 V DC nominal (8 to 36 V DC continuously)
UL/cUL Listed: 10 to 32.5 V DC
0 V DC for 50 ms when coming from at least 8 V DC (cranking dropout)
Consumption: Typical 3 W, maximum 5 W
The auxiliary supply inputs are internally protected by a 12 A fuse (not replaceable) (fuse size
determined by load dump requirements).
Voltage withstand: ±36 V DC
Load dump protected by TVS diodes.
