SWS
600L, 1000L
change about 400mV (3V, 5V), 5% (12V, 15V, 24V, 36V, 48V,
60V) in its transient response.
Method (A)
Method (B)
Isolation Test
Isolation resistance between output and (chassis) shall be
more than 50M
Ω
at 500VDC and between output and AUX,
CNT, ALM shall be more than 50M
Ω
at 100VDC. For safety
operation, voltage setting of DC isolation tester must be done
before the test. Ensure that it is fully discharged after the test.
Output - FG (chassis) : 500VDC 50MΩ or more
Output - CNT
･
AUX
･
ALM : 100VDC 50M
Ω
or more
Withstand Voltage
SWS600L is designed to withstand 3.0kVAC, SWS1000L is de-
signed to withstand 4.0kVAC between input and output. This
series is designed to withstand 2.0kVAC between input
and (chassis), 500VAC between output and (chassis), and
100VAC between output and CNT, AUX, ALM terminal each for
1 minute. When testing withstand voltage, set current limit of
withstand voltage test equipment at 20mA.
(Output - (chassis) and Output - Control : 100mA).
The applied voltage must be gradually increased from zero
to testing value and then gradually decreased for shut down.
When timer is used, the power supply may be damaged by high
impulse voltage at timer switch on and off. Connect input and
output as follows.
Input - Output (dotted line): 3.0kVAC 1min. (20mA),
(SWS1000L: 4.0kVAC 1min 20mA)
Input - (chassis) (solid line) : 2.0kVAC 1min. (20mA)
Output - (chassis) : 500VAC 1min. (100mA),
(SWS600L-60: 651VAC 1min 130mA)
