4 Peak Loading
5.1 Option outline
¡
Consult us detailed option and delivery before hand.
¡
While some combinations of options are possible, some combina-
tions are not. Please consult us for details.

The difference from standard is shown Table 5.1.
¡
Peak load is possible to draw as below.
¡
Ensure that the device is used in accordance with the following
conditions, as failure to do so may result in damage to internal
components.
¡
Due to the nature of a pulse load, a power supply may make a
sound (noise). If the unit is used in a quiet place, consult factory
for the load condition in advance.

5 Option
¡
Output voltage in parallel operation is adjustable by using the po-
tentiometer of the “master” unit. Select one power supply to be
the master, and turn the potentiometer of the other, “slave” power
supplies, clockwise to the end. Then use the potentiometer of the
mater to adjust output voltage.
¡
When the output current is less than 5 to 9% of rated output
current(ACIN200V at forced air), the output voltage fl uctuates oc-
casionally. The minimum current is different depend on the model
and the number of parallel operation, so please consult us at any-
time.
¡
In parallel operation, output voltage increases like stairs due to a
delay of the rise time of output voltage at turn on.
