PWM input

(5V line) Note 2)

Note 1) To prevent chances of signal oscillation, a series resistor (1k

Ω) coupling at each output is recommended.

Note 2) By virtue of integrating a photo-coupler inside the module, direct coupling to CPU, without any extemal opto or transformer isolation is possible.

Note 3) All outputs are open collector type. Each signal line should be pulled up to plus side of the 5V power supply with approximately 5.1k

Ω resistance.

Note 4) The wiring between power DC link capacitor and P/N terminals should be as short as possible to protect the ASIPM against catastrophic high surge voltage.

For extra precaution, a small film snubber capacitor (0.1~0.22

µF, high voltage type) is recommended to be mounted close to these P and N DC power input pins.
