3-10. Peak Output Current
For ZWS150PAF series, the peak output current should
satisfy the conditions below:
1)Should not exceed the rated peak current in the
2)Duty cycle of the peak output current should be < 35%,

3-11. Remote ON/OFF Control
Remote ON/OFF control (CN2,CN52) function is avail-
able. Using this function allows the user to turn the output
on and off without having to turn the AC input on and off.
Remote ON/OFF control can be used by following 2 modes.
However, for Cover and Chassis type (eg. ZWS150PAF/A,
/JA, /TA, /SA) cannot be used.
