Supplying Power to the Unit
The TRACER MPS can operate from a supply between 21 and 63 Volts DC, with either polarity referenced to ground, and consumes
3 Watts nominal, 20 Watts peak (during relay switching). Current required (in Amps) is determined by dividing the power consumed (in
Watts) by the applied voltage (in Volts). As an example at 48 Volts, the TRACER MPS would draw approximately 0.417 Amps peak (20
Watts / 48 Volts).
