Isolation Test
Isolation resistance between output and (chassis) shall
be more than 100MΩat 500VDC and between output and
CNT・PF shall be more than 10MΩ 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 100MΩ or more
Output - CNT · PF : 100VDC 10MΩ or more
Note 1. "PC" and "COM" are NC in HWS300P.
Withstand Voltage
This series is designed to withstand 3.0kVAC between
input and output, 2.5kVAC between input and (chassis),
500VAC between output and (chassis), and 100VAC
between output and CNT・PF terminal each for 1 minute.
When testing withstand voltage, set current limit of
withstand voltage test equipment at 20mA.
(Output- (chassis) and Output-CNT・PF: 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.
In the test by state of output open, there is a thing that
output voltage is generated momentarily.
Input - Output (dotted line) : 3.0kVAC 1min. (20mA)
Input - (chassis) (solid line) : 2.5kVAC 1min. (20mA)
Output - (chassis) : 500VAC 1min. (100mA)
Output - CNT· PF : 100VAC 1min. (100mA)
Note 1 "PC" and "COM" are NC in HWS300P.
Note 2 This product have monolithic ceramic capacitor in
secondary circuit to frame ground.
