5. Features and Functions

5.1. Diode Protection

The BDx Module provides a network of heatsink-mounted diodes, tied together using copper bus bars. An internal auxilary power supply with a microprocessor provides and control power, while also performing housekeeping and monitoring functions. The BDx Module provides a turn-key blocking diode solution with internal monitoring and plug & play integration with Magna-Power’s MagnaDC programmable DC power supplies. Integration with other products is possible, as long as faults are properly monitored to provide a safe shutdown.

5.2. Temperature Monitoring

The BDx Module contains internal fans to remove the heat produced by the diodes. The BDx Module uses thermistors to monitor heatsink temperatures. In the event of a thermal alarm, the BDx Module will indicate a fault via its front status monitoring LED (blinking green) and on its rear 15-pin interface connector (+5V on Pin 2).

5.3. Power Supply Shutdown

The BDx Module communications with a MagnaDC programmabe DC power supply using the provided Interface Cable. In the event of a faulted status on the BDx Module, it will break an interlock connection to the power supply, forcing the system to shutdown down. When the fault has been resolved on the BDx Module, the interlock connection will restored and the fault can be cleared on the power supply.

5.4. Statuses

The BDx Module has various statuses corresponding to its present state of operation. A front panel status indicator LED provides information about the BDx Module’s operational status, as defined in the following table:

Off

BDx Module is disabled or not powered on.

Solid Green

BDx Module is powered on an all systems are normal.

Blinking Green

There is a fault in the BDx Module and the product should not be operated.

Caution

Ignoring faults and repeatedly operating the BDx Module while in a faulted state will eventually result in product damage.
