7 Series Operation
For series operation, either method （A） or （B） is possible.
8 Parallel Operation
１． Set power supply output voltage higher by the forward
２． Adjust the output voltage of each power supply to be
３． Use within the specifications for output voltage and
9 Peak Output Current
For ZWS-AF series, relation with average output current
and peak output current must satisfy formulas below. Also
operating time at peak output is less than 10sec.
When using pulse load, audible noise can be heard from

 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 & Chassis type （MODEL: ZWS-AF/
JA） , can not be used.
＊Using CN2
It is controlled by short or open between +R & -R of CN2.
CN2 is provided in the primary circuit for ON/OFF control
by means of a switch or other device. When using this con-
nector, which is considered to be electrically connected to
the mains input voltage, all the requirements of EN60950
must be met with respect to the connector. wiring and
switch etc.
In particular :
1) Basic insulation must be provided between the ON/
2） Reinforced insulation must be provided between the
3） Wiring must be routed such that damage to the insula-
4） The switch must meet requirements for reinforced insu-
[CN2] The control mode is shown below.
＊Using CN52
At first, remove short piece of CN2.
It is controlled by the voltage applied to +R and -R. This
circuit is in the secondary （ output） side of the power supply
unit. Do not connect in the primary （ input） side. And this
circuit is isolated from the output by a photo-coupler.
