APPENDIX 1    LOAD PROTECTION FUNCTION 

93 

 

A1-4. OUTPUT IS TURNED ON/OFF WITH A MECHANICAL SWITCH                 

When the output voltage is higher than 100V and using a magnetic contactor as the switch, the arc may generate. 

The noise may enter the power supply differential amplifier through the load line and cause the output to become 

unstable. The noise can be absorb by add a RC connected in parallel. When using the remote sensing, always turn 

the sensing cable ON and OFF simultaneously. 

 

 

 

A1-5. WHEN THE LOAD DRAWS THE PULSE CURRENT 

When connected to the PWM load, although some times the measured current value (Mean or RMS) is lower than 

the rated current of the power supply. But the peak value is exceeding the rated value. The output voltage in this 

case will still drop. However, if the pulse width is narrow or the peak value is not too high, the user can solve this 

problem by install a large capacitor at the load side.

connecting a DC TO DC
