J.S.T
2.1 Input Voltage Range
The input voltage range is AC300-480V (three phase four wire).
¡
For the safety standard test, the input voltage range is AC346-
¡
415V (three phase four wire, 50/60Hz).
The current owing through the neutral line (N phase) increases
¡
when the AC input voltage is over AC456V three phase four wire
(18Amax). This does not affect product quality. Please select a
suitable wire gauge for the neutral line.
L1
AC300 - 480V
L2 L3
N
Three phase four wire system
Three phase three wire input voltage is not supported.
¡
The neutral line must be connected.
If the input voltage is not from three phase four wire connection or
out of the specied range, the unit will not operate properly and/or
may be damaged. If you need to apply a square wave form input
voltage, which is commonly used in UPS and inverters, please
contact us.
2.2 Inrush Current Limiting
An inrush current limiting circuit is built-in.
¡
If you need to use a switch on the input side, please select one
¡
that can withstand an input inrush current.
Relay technique is used in the inrush current limiting circuit. When
¡
you turn the power ON/OFF repeatedly within a short period of
time, please have enough intervals so that the inrush current limit-
ing circuit becomes operative.
When the switch of the input is turned on, the primary inrush cur-
¡
rent and secondary inrush current will be generated because the
relay technique is used for the inrush current limiting circuit.
