3. Operating requirement

（1）In some case for convenient wiring, the green wire and red wire can be wired together, then

connected to the control terminal that can supply power just for the purpose of executing control and

energy supply at the same time. However, when using this control mode for 0~+500V output, the

relationship between output voltage and the control voltage is not exact the magnification times 100

relationship.

（2）If power output is greater than 600μA and using the control mode to wire the green wire and red

wire together, the magnification relationship between the output voltage control terminal voltage and

the output voltage might be less than 100. The greater the power output, the smaller the magnification

times.

（3） Never let the environmental temperature be higher than the highest working temperature of the

module for a long time. The module can work reliably for a long time without any heat damage within

rated working temperature range. The maximum laboratory time is 200h continuous working. However,

after working environmental temperature is higher than the rated working temperature, the damage and

aging of elements, devices and materials would speed up.

（4）If it is required to make the HV output ripple smaller for application, just wire a RC filter using

the self-contained resistances and HV capacitances; in such way, the ripple can be less than 1 mVp-p in

general. See the attached drawing for the wiring method for the RC filter.
