8. Functions

8-1 Adjustable output voltage

Output voltage can be set by applying 0 to 10V between the terminals for output voltage control, the Vcont

(4Pin) and SGND (3Pin). Avoid setting out of the adjustable output voltage range or it may cause trouble.

8-2 Monitoring output voltage and output current

Output current monitoring terminal, the Imoni (7pin) and output voltage monitoring terminal, the Vmoni (8pin)

generate 0 - 10V proportionate to output of the converter.

An internal impedance of each terminal for monitoring is 1kohm. The internal impedance of each terminal for

monitoring is 1k

Ω. Do not allow monitoring current to exceed 2mA

PGND, SGND, casing and HV GND are connected inside.
