Ratings, Characteristics, and Functions
*1.
Do not use an inverter output for the Power Supply. Inverters with an output frequency of 50/60 Hz are available, but the rise in the internal
temperature of the Power Supply may result in ignition or burning.
*2.
For details, refer to
Output Voltage Adjuster (V. ADJ)
on page 16.
*3.
Specified for the rated input voltage (100 VAC) and a 100% load.
The measurement method is based on JEITA standard RC-9131B.
For details, refer to
Ripple Noise Voltage
on page 17.
*4.
To reset the protection, turn OFF the input power for three minutes or longer and then turn it back ON.
*5.
The weight is for an open-frame model.
*6.
The range for compliance with EC Directives and safety standards (UL, EN, etc.) is 100 to 120 VAC (85 to 132 VAC).
*7.
Class B compliance was met with an aluminum plate placed under the Power Supply.
*8.
Excluding models with low leakage current.
