Bosch Coolant Pump

This Bosch PCE pump is ideally suited for cooling EV battery and motor systems. With a robust, brushless design these are intended for continuous operation, and a long service life. These pumps can be enabled by just supplying power and ground, but also have the option for full speed control and diagnostic information via the PWM pin.

PWM control requires a signal that is switched to ground to generate the low level. The pump has an internal pull-up resistor for the high level. For on/off control the PWM pin should not be electrically connected. 

Diagnostic information available upon request.
