Remote ON/OFF
Example of using Remote ON/OFF
Option ‘-R’
Voltage Applied Between
Output
If external power source is in the range of 4.5-12.5 V, current limit resistor R is not
required. If external power source exceeds 12.5 V, current limit resistor R must be
connected.
RC (+) and RC (-)
SW ON
(4.5 - 12.5 V open circuit)
SW OFF
ON
To calculate the current limit resistance use following equation:
OFF
(0-0.5 V short circuit)
R (Ω) = Vcc - (1.1+Ri x 0.005)
0.005
Where;
Vcc = External Power Source
Ri = The internal resistance (780Ω)
Remote ON/OFF circuit (RC (+), RC (-) ) is isolated from input, output and FG.
Alarms
Option “-W”
Alarm
Output of alarm
Open collector method
Good: Low
(0-08. V, 1 mA max)
Fail: 50 V max
• -W is available for detecting low input alarm (PF), detecting low
output voltage (LV) and operating N+1 redundancy.
• Alarm specifications are shown in Table.
If line voltage falls below 85 VAC
PF or fan stops
• Each alarm (PF, LV) is isolated from input, output and FG.
If the output voltage falls out of specified
Open collector method
Good: Low
Notice:
LV 1. When the output is over current
(intermittent current), the alarm is
unsettled status.
(0-08. V, 1 mA max)
Fail: 50 V max
2. When parallel operating without
connecting diode,
LV alarm is not operating.
