Frequently asked questions
What is the maximum output current?
At 15 V and 2 W, the maximum output current is about 133 mA (2 W divided by 15 V). Keep the load below this to stay within the rated power.
How should I wire the input and output grounds?
Because the module is isolated, its input ground and output ground are not internally connected. Connect the 12 V supply to the input pins and the load to the output pins, and wire each ground to its own side as the datasheet shows.
