Output voltage accuracy

When the nominal input voltage, the rated output load,the percentage of difference between nominal output and rated output voltage and rated output voltage.

For example, our DC-DC power module WKD5-24S05, rated output voltage 5V, rated load current 1A, nominal input voltage 24V, tested output voltage is 5.01V, output voltage accuracy =

Efficiency test

When the nominal input voltage, the output full load, record input voltage and input current, output voltage and output current; Input power= input voltage x input current, output power= output voltage x output current, and the conversion efficiency is calculated according to formula (3)

Noted : Po-output power; Pi-input power.

Isolation and withstand voltage test

Set the test time, leakage current, test voltage and test voltage rise rate (less than 50% of the test voltage and gradually increase at≤500V / s); Short circuit connects all input pins and all output pins to DC-DC Converter, and connect the test terminal between the two points tested to meet the index requirements.
