DLM 600W Series

2.14 Special Application Warning
The DLM600 family of supply requires freewheeling and blocking diodes while driving
inductive loads or batteries to protect the power supply from damage caused by power
being fed back into the supply and from high voltage transients.
2.14.1 Suggested Procedure for Diode Selection
The Peak Reverse Voltage ratings should be a minimum of 2-3 times the Power Supply
maximum output voltage. The Continuous Forward Current ratings should be a
minimum of 1.5 times the Power Supply maximum output current. Heatsink may be
required. There also may be a need for higher voltage rated parts, dependent on load
circuit design and inductor values.
