PT20 Battery Guard - 20A 12/24V

The PT20 Solid State Battery Guard is designed to protect automotive and commercial vehicle batteries from deep discharge. It continuously monitors voltage levels and disconnects equipment if the battery drops below a safe threshold, ensuring there’s always enough power left to start the engine or run critical systems. Compact and easy to fit inline, it’s ideal for medium-load circuits such as lighting, pumps, radios, and auxiliary accessories.

Key Features:

• Continuous rating: 20A @ 12/24V DC

• Inline design – simple to connect within wiring harnesses

• Over-current, overheat, transient, and catastrophic protection

• Input voltage: 9–32V DC (auto-sensing)

• Typical quiescent current: 2mA @ 13.6V

• Compact, lightweight, and IP-rated for harsh environments

Also available in a timed version, which disconnects the load after a preset period once the ignition is turned off.
