3. Product Introduction¶
3.1. Features at a Glance¶
The BDx Module offers a turn-key rack-mount blocking diode solution, including:
Fully integrated and enclosed heatsinking and fan cooling
User I/O status feedback including a temperature alarm state
Front panel status indicator
Heavy-duty tin-plated copper bus bars
Remote sensing terminal for voltage feedback compensation
Universal single phase active-PFC AC input connection
Internally, semiconductors are secured to Magna-Power manufactured heatsinks with fans and integrated thermocouples. An internal microprocessor monitors the internal temperature and provides +5V digital output signal when the system is powered and in a normal operating state. This +5V signal can be easily integrated into interlock systems, to ensure power is only driven through the BDx Module when its powered on and cooling is functional. Additional, a +5V digital input allows control of when the BDx Module is turned off and on, providing complete integration with a connected power supply.
A quick summary of the BDx Module key features:
Add-on module for MagnaDC power supplies
4 models addressing broad range of applications
Protection up to 1,200 Vdc
Forward current up to 1,200 Adc
Fully integrated cooling with status indicator
Power supply user I/O controls interface
Included fixed rail rack-mount kit
