5) SW2 is used to enable or disable the converter.

For positive logic module, When SW2 is pose for the ON position, the converter is ON, and SW2 is pose for the OFF position, the converter is OFF.

For negative logic module, When SW2 is pose for the ON position, the converter is OFF, and SW2 is pose for the OFF position, the converter is ON.

6) SW3 is used for the Output Voltage Set-Point Adjustment Range. By an external voltage source:

If the converter requires a trim up, put the SW3_1 to ON position.

If the converter requires a trim down, put the SW3_2 to ON position. By an external resistor:

If the converter requires a trim up to Vo,set, put the SW3_8 to ON position. If the converter requires a margin trim down, put the SW3_3 to ON position. If the converter requires a margin trim up, put the SW3_4 to ON position.

The SW3 Function table is listed as follows:

Note:

 

1.

The subdivide switch of SW3_1~4 must not be ON at the same time.

2.

For the SW3_5~7 use at NPA series, so must push to OFF position.

7.2 Initial Power Up

1) Turn the power supply ON, set the current limit on DC source (refer to specification of either converter) and increase the input voltage (use DVM2 to monitor the input voltage) until it reaches the desired value.

2) Set the switch SW2 to power module ON.

3) The converter is now operating, which can be verified by observing the DVM3 (appropriate value for the nominal output voltage) and channel 2 of the oscilloscope (appropriate value for the nominal output voltage).

4) Set the switch SW2 to power module OFF.
