The P945 is an 8-channel isolated load simulation module for the P940 modular power system. Each of the channels is galvanically isolated and can sink up to 40V/2A/40W. External inductors may be switched into the channels to allow simulation of relays, solenoids, torque motors, or other magnetically operated devices.
P945 simulated loads are bipolar and support positive or negative applied voltages with respect to the labeled terminals; the polarity of the input signal only impacts polarity of reported voltage and current measurements.
The P945 is available in two variants. The P945-1 can draw up to 2A per channel and is optimized for simulation of high-power loads such as solenoids or contactors. The P945-2 trades current handling capability for precision measurement of small currents and is optimized for smaller, precision loads such as torque motors.
As a part of the P940 system, the P945 is easily synchronized with other P940 modules, enabling system architects to build whatever power and simulation environment they may require.
