TDK-Lambda
HWS1000/ME Series
INSTRUCTION MANUAL
5-13. Withstand Voltage
This series is designed to withstand 3.0kVAC between input and output, 2.0kVAC between input and E (chassis),
500VAC between output and E (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-E (chassis) : 300mA, 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. If output is left open during test, output voltage might appear momentarily.
This product have monolithic ceramic capacitor in secondary circuit to frame ground.
Some of the withstand voltage tester may generate high voltage at the matching with monolithic ceramic capacitor and
may cause the unit damage.
So, please check the waveform of test voltage.
