★In the case of the dedicated AC adapter (AD-K120P100), the red wire at the end of the cable is + voltage.

2. About input signal

It can handle the voltage range of 0~+5V, and the GND terminal side is a ground-level single-ended input.

The signal input is an input voltage of +5V, and the output voltage is +150V.

3. About output current

The output current is limited to approximately 5mA according to the current limiter.

In addition, if the temperature of the device rises in an overload state, the thermal SW of approximately 60°C will block the operation output.

(Thermal SW will automatically recover when the temperature drops)

4. About insulation

The shell FG (8-pin) of this device and the input and output GND (2, 4, 6, 7 pins) are separated and insulated and not connected.

When connecting the box to GND, please connect the included short strip between terminals 7-8.

(When shipped, the short rod is attached.)
