Battery Protect Relay (12V/500A)

In addition to controlling the TBP remotely, buttons on the top also provide a way to open or close the main contact locally. This is also required for maritime applications. For external control, the TBP is equipped with a 5-wire interface cable. There is a possibility to realize signals for opening and closing the main contact via a two- or single-wire control. This for optimal flexibility. The TBP is a bistable relay, which means that there is no power consumption from the battery when the main contact is in a closed position. This is a major advantage compared to regular relays that require a (sometimes significant) holding current to keep the contact closed. In addition to all the features and benefits of the RBS, the TBP has built-in protection against deep discharge of your battery. It will automatically open the main contact once the battery voltage has dropped below a programmable undervoltage level. If the battery voltage subsequently rises above the programmable restart voltage, the main contact is closed again. Another useful TBP feature is Bypass Mode. In situations where the TBP has opened the main contact due to a battery undervoltage, a long press of the close button (local or remote) will close the main contact for 1 minute. This allows the user to still connect a switched off system with an almost empty battery to, for example, a charging source such as an inverter/charger combination. If the battery voltage remains too low after this minute, the contact will open again. But it remains in a closed state if a connected battery charger is sufficiently restoring voltage during the bridging time.
