Available 3–24V DC // 500mA or 1100mA

DevGuard 24

Inline protection for the wiring mistake you only need to make once. DevGuard 24 sits between a DC source and your project to block reverse polarity, clamp voltage spikes, and limit sustained overcurrent.

DevGuard 24 installed inline between red and black DC power wires
Source to IN. Project to OUT. No configuration required.

Protection // Three Layers

Small board. Focused job.

01

Reverse Polarity

A P-channel MOSFET blocks power when the source is connected backward, without putting a series diode in the normal current path.

02

Surge Clamp

A TVS diode suppresses short voltage spikes before they reach the protected circuit.

03

Resettable Fuse

A polyfuse limits sustained fault current, then resets after the fault is removed and the device cools.
