Introducing the new Battery Protect Relay from TBS Electronics

26 October 2020

TBS Electronics has a new addition to its DC Modular range, the new 'Battery Protect Relay'. This Battery Protect (TBP) is a smart latching contactor for DC currents up to 500A and is suitable for 12V, 24V and 48V systems with a low supply current of less than 100µA.

The TBP has a number of additional features. Most importantly, it can protect your battery without the need of an external measurement and control device. It will automatically open the main contact once the battery voltage has dropped below a programmable low voltage level. When subsequently the battery voltage has risen above the programmable reconnect voltage, the main contact is closed again. It is also suitable for Li-ion battery’s due to its very precise adjustment possibility. 
Another handy TBP feature is the override mode. In situations where the TBP has opened the main contact due to a battery under voltage, long-pressing the close button (local or external) will close the main contact for one minute. This allows the user to jumpstart a low battery system. When, after this minute, the battery voltage remains too low, the contact will open up again. But it remains closed during the override time, a charger is connected causing the battery voltage to recover.
