6.4Thermal Characteristic Efficiency

7.0Test Set-Up

7.1Initial Set-Up

1)Examine the part number of the power module to determine that the correct module is being evaluated. Note: DNM04S0A0S10P A would denote the SMT package, while DNM04S0A0R10P A would denote the SIP package. This Evaluation Board is for SIP package.

2)Set the multi-meter DVM1 to the DC current 20A range. Set multi-meters DVM2 and DVM3 to DC voltage, auto ranging.

3)Electronic Load

Turn on the Electronic Load at CR mode (or resistive load) and adjust the current level. The maximum rated output current is 10A for the model DNM series and 16A for the DNL series. Ensure the output load does not exceed the recommended maximum current.

4)SW1 is used for on/off Transient function test. Turn SW1 to the OFF position if this function is not being used. Turn SW1 to the ON position if the Transient function test is required.
