Specifications
Ratings, Characteristics, and Functions
*1. The value is when both rated output voltage and rated output current are satisfied.
*2. Do not use an inverter output for the product. Inverters with an output frequency of 50/60 Hz are available, but the rise in the internal
temperature of the product may result in ignition or burning.
If the input is connected to a UPS, do not connect a UPS with a square-wave output.
Doing so will cause the internal temperature of the product to increase, possibly causing smoking or burning.
*3. The value for the leakage current is determined according to the Electrical Appliances and Material Safety Act.
*4. If the output voltage adjuster (V. ADJ) is turned, the voltage will increase by more than 28 V min of the voltage adjustment range. When
adjusting the output voltage, confirm the actual output voltage from the product and be sure that the load is not damaged.
*5. A characteristic when the ambient operating temperature of 25°C.

Our shared Value Design for Panel (herein after referred to as Value Design) concept
for the specifications of products used in control panels will create new value to our
customer's control panels.
Combining multiple products that share the Value Design concept will further increase
the value provided to control panels.
