433MHz Wireless Remote Control DC 8-72V 30A Relay Power Switch

This remote-controllable power switch is easy to setup and operate, with many uses for hobbyists, industrial users, even those in theatre or film production. It could be used to control lighting, doors, security systems, pumps and other appliances.

Specifically designed for DC applications, it supports a voltage range of 12–72V DC and a maximum power of 2100W (30A). This model is unsuitable for powering AC devices. Its compact size, low standby current (≤20mA), and stable operation make it a reliable choice for versatile wireless control.

The system comprises a keyring remote control and a receiver unit that connects to your power source and device. Operating at 433 MHz with ASK modulation and high sensitivity (110 dBm), it ensures reliable communication with an effective range of about 70 meters (line-of-sight, reduced by obstacles).

The controller features four modes of operation, easily configured via the remote:

• Momentary: Relay activates while the remote button is pressed.
• Toggle: Relay alternates between on and off states with each press.
• Latched: Relay stays on after pressing one button and turns off when another is pressed.
• Delay: Relay activates on a button press and deactivates after a set time.

This functionality makes it a practical solution for applications requiring flexible wireless control.
