Fully integrated
High-power rack-mount blocking diode solution
For applications or products where the Integrated Blocking Diode (+BD) option is not available or desired, 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.
Back EMF Protection
Prevent back-electromotive force (EMF) from electric motors or from the connection of charged batteries and capacitors from flowing back into the output of your power supply.
High Voltage Protection
Protect your power supply and other DC power equipment from externally generated DC bus voltages that could exceed the equipment's maximum ratings.
Mixed Voltage Paralleling
Connect multiple power supplies with different voltage ratings in parallel and protect lower voltage products high bus voltages.
Prevent Load Discharge
Prevent the power supply's internal bleeder network from discharging batteries, capacitors or fuel cells when the power supply is standby, faulted state, or turned off.
Model Ordering Guide
BDx Module models are defined by the configuration type and number, the maximum DC input voltage rating, and the maximum current rating.
