Power Requirements
System requires a clean, steady power source for reliable performance of the high frequency CPU
on the product, the quality of the power supply is even more important.
- If the fluctuation of power supply voltage is beyond the product specifications, connect a constant
voltage transformer.
- If the noise is large, connect an isolation transformer (a noise cut transformer).
- Never bundle, place nearby or in parallel the power supply cable and the input /output signal lines.
- If lightning surge protection is required, connect the surge protective device (SPD).
- Ground of this product and the surge protective device (SPD) well away from each other.
- Please select the ones which do not exceed the maximum allowable circuit voltage of surge protective
device (SPD) at rising the power supply voltage.
- When you restart the power, give the product for at least one second (or more) of the power OFF time.
- When you use with the CPS-PWD-90AW24-01(by CONTEC), instantaneous voltage drop allowed
time will be 20 millisecond or less.
