3h Bus Contactor Shutdown Module

Details: 3h Bus Contactor Shutdown Module

3h Bus Contactor Shutdown Module - EK 3H-OFF BNSP is designed to disconnect the 3h Bus in the EK BNSP 20000. The EK 3H-OFF BNSP is controlled by an external potential-free contact of the EK CPU BNSP-1 module.

After the EK BNSP 20000 has been operated on the battery for three hours without the presence of a power supply, the EK CPU BNSP-1 module by closing the potential-free contact triggers the 3h Bus termination process.

The EK 3H-OFF function of the BNSP module is to disconnect the contactor in the EK BNSP 20000, thus achieving a shut down of 3h Bus.
