DJUSTMENT
For models with only one output, the output voltage can be adjusted in the
range of -20%/+15%.

To increase the output voltage, connect an external resistor between the
TRIM-Pin and the negative output voltage (-Vout) and to decrease the
voltage, connect the resistor between the TRIM-Pin and the positive output
voltage (+Vout).

Please note that the adjustment range at very low input voltages is slightly limited for the 12V and 15V
model.
PYD20-72WS12:
Reduced trim range at
input voltages below 10Vdc
PYD20-72WS15:
Reduced trim range at
input voltages below 10Vdc
All parameters are typical values specified at nominal input voltage, nominal output load, 25°C ambient and after a 5 minutes run-in time unless
otherwise noted. The information presented in this document is believed to be accurate and reliable and may change without notice.
