(1): Peak current is based on the software current limit. 25 amps is the standard current limit for a 12V pump and 15 amps is the standard
current limit for a 24V pump for serial numbers > 07065826.
(2): The pump shuts down when the internal controller temperatures reaches 130˚C at this point the pump will stop running until the internal
controller temperature drops below 125c. Once the safe value is reached, the pump will restart. No ignition cycle is required to restart the pump.
(3): The inrush current occurs when the controller first receives the required voltage on the ignition pin. This current inrush is due to the
charging of the bulk capacitors in the controller. The inrush current numbers are worst case. They were measured with a battery as the source
with a harness that was 3ft in length (very low source impedance). Anything done in the application to increase the source impedance will have
a significant (downward) impact on these numbers. This current is not generated every time the motor is started, but only when the ignition line
is first applied.
