Output Voltage/Current Adjustmen

3.5.1

General adjustment

Output voltage can be trimmed by adjusting SVR (

), please utilize an insulated cross-head screwdriver to

on the terminal end

make an adjustment.

3.5.2

Adjustment with an external 0 - 5Vdc source (Output Voltage Programming)

(1)

Connect output of the external DC source to PV (PIN5 or PIN6) and -V (PIN1) on CN55, shown in Figure 3-1.

(2)

Relationship between output voltage and external DC source is shown in Figure 3-2.

(3)

While increasing the output to a higher voltage level, please reduce the load current accordingly. Output wattage of the

unit should not exceed the rated value under any circumstances.

Note

:

The PHP-3500 will trigger OLP to shut down itself if the output stays at constant current level condition for more than

5 seconds.

Output current adjustment (Output Current Programming)

Constant current level can be adjusted within a range of 20 -100% of the rated current via an external DC source, wiring

is shown as below.
