How is the manual override activated?

Manual override is activated by connecting the override wire to 12V DC, which bypasses the automatic voltage sensor to engage the relay below set voltages.

What is the recommended fuse size?

A 100Amp fuse is recommended for this relay.

Does the relay come with a warranty?

The product description does not specify a warranty period, but it includes a CE certificate.

Product Q&A

Q:How does the relay protect the battery system?

It monitors voltage and engages when charging is detected (13.0-13.4V) to join banks, and disconnects if voltage drops below 12.6-12.8V to prevent excessive drain.

Q:Can this relay assist in engine starting?

Yes, optionally. If the chassis battery is lower than the auxiliary bank, it engages to allow the auxiliary battery to aid starting, provided the start signal is at least 3V.

Q:What is the disconnect delay time?

The relay has a 5 to 10-second disconnect delay to prevent disconnection during momentary voltage drops.

Q:Is the relay suitable for harsh environments?

Yes, it features a solid-state sealed design with IP66 rating to protect against oil, gas, salt, water, and dust.

Q:What is the continuous current rating?

The Smart Voltage Sensitive Relay Sr200as supports a continuous current of 200A and an intermittent current of 400A.
