What is the maximum current capacity?

The relay supports a continuous current of 100Amp and an intermittent current of 200Amp.

How do I activate the manual override function?

Connect the override wire to 12V DC. This bypasses the automatic sensor, allowing engagement below set voltages.

What certifications does the product have?

The product holds a CE certificate, ensuring it meets relevant safety and quality standards.

Product Q&A

Q:How does the relay protect the battery system?

It monitors battery voltage. When voltage reaches 13.0-13.4V, it engages to join banks. If voltage drops below 12.6-12.8V, it disconnects to prevent excessive drain.

Q:What are the engage and disengage voltage settings?

The engage voltage is 13.3Vdc, and the disengage voltage is 12.8Vdc.

Q:Does the relay have a delay before disconnecting?

Yes, there is a 5-10 second disconnect delay to prevent disconnection during momentary voltage drops.

Q:Is the device waterproof and dustproof?

Yes, it features an IP66 rating with a sealed solid-state control box to protect against oil, gas, salt, water, and harsh environments.

Q:Can the auxiliary battery help start the engine?

Yes, if the chassis battery voltage is lower than the auxiliary bank, the relay engages to allow the auxiliary battery to aid in starting.
