4-10. Output Dynamic Load Response
During output dynamic load test (0%-100% load), the
output voltage level might experience a higher voltage dip
of -8% (typ).
For example, VIN = 230VAC Dynamic Load = 0% - 100%
Ta = 25degC, the output voltage level dip will be -8% (typ).
5. DC OK
In normal operation the DC OK (optocoupler) is closed
when the output voltage is greater than 80% of nominal
output voltage. When the output is less than 80% of
nominal output voltage the optocoupler is open.
6. Mounting Directions
Recommended standard mounting method is vertical with
the output connector uppermost. Do not exceed the load
deratings. See section 7. Leave enough space surround the
units to ventilate heat efficiently.
Minimum Installation clearances:
40mm on top, 20mm on the bottom, A=5mm which is
recommended on the left and right side when products are
permanently loaded with full 120W. In case the adjacent
device is a heat source, A=15mm clearance is recommended.
The ambient temperature (T

6.1. Power supply mounting on DIN RAIL (TS35
or equivalent)
Make sure input and output wire disconnected when
mount power supply onto rail
(1) Tilt the unit slightly rearwards, fit the unit
over top hat rail.
(2) Slide it downward until it hits the stop.
