Operation Procedure

Necessary Equipment

(1) AC power supply (90 Vac to 264 Vac, 10 W or more)

(2) Oscilloscope

Connect to Each Equipment

(1) Set the AC power supply to 90 Vac to 264 Vac power supply off.

(2) Connect the output pin (ACOUT-pin, COMMON pin) to Oscilloscope (Insulation isolated).

(3) Connect the pin of the power supply (CN1) to AC power supply output with pair of wires.

(4) Connect the Multi-meter to DCOUT-pin and GND-pin

(5) AC power supply turn on.

(6) Confirm the output waveform synchronized with the AC voltage.

(7) The DCOUT terminal outputs about 1/100 voltage with the DC voltage after the diode rectification.

Caution

：

To avoid the electrical shock , please keep Oscilloscope probes being isolated.
