Description

• Adjustable Overvoltage Cutoff (5–30 V): Set your cutoff threshold by turning the onboard potentiometer. When input voltage exceeds the limit, Protect automatically shuts off the output and auto-recovers when conditions normalize.
• Reverse Polarity & Reverse Current Protection: Acts like an ideal diode with only a 13.5 mV typical voltage drop up to 14 A. Prevents damage from incorrect power connections and supports ORing multiple supplies for redundancy and fault isolation — if one source fails, the others carry the load with no backfeed.
• Solid-State Reliability: No relays, no clicks. Just dependable, fast-acting MOSFET control. Designed for longevity and high reliability in demanding applications.
• Power Switch Capability: Use a low-current mechanical SPST switch to toggle high-power loads via the Enable terminal block. No bulky high-current switches needed. When points 1 and 2 are connected, the module is OFF.
• Opto-isolated Fault Output: Opto-isolated fault pin goes LOW during an overvoltage event—useful for system diagnostics, alerts, or shutdown logic.
• Dual Status LEDs:
  • SAFE = Power is safely flowing
  • FAULT = Overvoltage fault detected and output disconnected
• Compact & Mountable: 54.5 x 38.5 mm PCB with four M2 mounting holes. XT60 connectors make it easy to install inline with your system or stack multiple modules for power ORing.

This module is made to block reverse current flowing from the output back to input, so if your power distribution system is regenerative, this product is not for you.

This module uses high-quality XT60 connectors and is rated for up to 25 A of continuous current at 25 C ambient temperature. Wire-to-Board XT60 connectors and heathshrink are included with each module.
