5V High power relay 250V 30A

Is your small relay constantly sticking? Then too high a current is passing through it. In that case, use this high power relay.

Switches current up to a maximum of 30A at 250V, that's no less than 7,500 Watts!

Supply voltage 5V
Control signal 3V - 5V

With optocoupler isolation.

Both NC (Normally Closed) and NO (Normally Open). This means you can choose what the relay does in its idle state (without power). With NC, the relay makes contact when there is no power, and with NO, it does not make contact when there is no power. This way, you can always choose the desired method for your project.

With power indicator and active indicator.

Specifications:
Type: 1-Channel
Relay Voltage: 5V
Output Capacity max: DC 30V 30A or AC 250V 30A on the NO (max 20A on the NC)
Idle Current: 5mA
Maximum Current: 5V: 190mA
Trigger Current: 5mA
Module Size: 66x40x22mm

Excellent relay. Also works with a 3.3V control signal (ESP32 etc). With LEDs for both power and activation indication, and you can select active-high or active-low with a jumper.

better than expected...
★★★★★Richard Broekhuis10-11-2025

I was under the impression that the same software worked as the other smaller USB relay version.
★★★★★Chris van der Zwaal09-07-2025

Great!!!!!!

The relay was on a small circuit board with no description. Luckily I only needed the relay, so I desoldered it from the board.
