Complies with FCC Part15-A, CISPR32-A, EN55032-A, VCCI-A with an external EMI/EMC filter. (refer to

Instruction manual)

CASE SIZE/WEIGHT

COOLING METHOD

Forced cooling (internal fan)

*1

AUX output power is not included.

*2

The current flowing through the neutral line increases when AC input voltage is over

AC456V 3f 4-Wire. The flowing current will vary according to the input voltage and the

load current. The maximum flowing current will be 18A.

*3

The current of input surge to a built-in noise filter (0.2ms or less) is excluded.

*4

Measured by 500MHz oscilloscope.

Ripple and ripple noise is measured on measuring board with capacitor of 22mF within

150mm from the output terminal.

*5

Drift is the change in DC output for an eight hour period after a half-hour warm-up at 25C,

with the input voltage held constant at the rated input/output.

*6

Can't be used above the rated output current and the rated output power.

*7

When the output voltage is adjusted to higher than 49.92V and the load factor is over 70%

of the rated current, if the load current changes quickly (< 200msec), the output voltage

drops approximately 5V below the setting voltage.

*8

When the output voltage is adjusted to higher than 149.82V and the load factor is over 70%

of the rated current, if the load current changes quickly (<200msec), the output voltage

drops approximately 15V below the setting voltage.

*9

Output voltage recovers from protection by shutting down the input voltage and waiting

more than 10 seconds then turning on AC input again, or turning off the output voltage by

remote control.

*10 Please contact us about another class.

*11 Case size contains neither the terminal blocks, connector and screw.

*

To meet the specifications, do not operate over-loaded condition.

*

A sound may occur from power supply at peak loading.

*Make sure necessary tests will be carried out on your end equipment with the power supply installed in accordance with any required EMC/EMI regulations.

Example recommended EMI/EMC filter

YAC-25-685

*A higher current rating EMI/EMC filter

may be recommended in view of the

other devices that could be connected

in parallel with the power supply.
