Mosfet Power Switch – pFET adapter

The pFET Adapter is intended to switch power loads up to 20A. It has P-channel power mosfet which means it is a high side switch and GND is directly connected to the load. The input control signal is galvanically isolated from the load and high voltage side. That way digital part has better EMC immunity and you can avoid ground loops or interference. The maximum voltage on the load side is 48V. For digital signal the minimum voltage is 3.3V and maximum at 5V. The adapter has small form factor with heatsink to dissipate heat when high power load is used ((!!CAREFUL, heatsink is connected to the OUTPUT voltage – do not connect to GND or any potential!!). The hole spacing on the PCB allows for mounting with our DIN rail moung adapter.

Features of pFET high side switch

  • 48V, 20A load capacity
  • 3.3V – 5V digital control signal
  • 1kHz load switching capacity
  • Optically isolated digital input
  • Heatsink for better heat dissipation
  • LED for visual signalling
  • DIN mounting option

For AC load switching we recommend SSR relay.
