FAQ

What is the maximum PWM input frequency supported by the PS12038?

The module supports a PWM input frequency up to 15 kHz when the case temperature is less than or equal to 100°C and the junction temperature is less than or equal to 125°C.

How does the PS12038 handle over-current protection?

The module detects over-current events with a trip level of approximately 46.5 Amperes and generates a fault output pulse after a delay of 10 microseconds. The protection operates for the lower arms only.

Is there an analog output for monitoring the DC-link current?

Yes, the module provides a Vamp output signal that corresponds to the inverter DC-link IGBT current, allowing for external monitoring and control.
