Specification
• The above specifications are in accordance with Electrical Appliance and Material Control Law, UL, CSA and IEC standards.
• No Ozone Layer Depleting Chemicals are used in these products or in their manufacturing process.
* Note 1: The temperature rise in Table 1 is a projected value based on temperature increase by the heat from DC resistance of the coil when the rated current (DC
or 50/60Hz) in Table 2 is conducted.
* Note 2: The temperature rise is affected by the mounting condition on the circuit board and the amount of harmonic distortion on the load current. Please make
sure that the temperatures of the coil and the terminals are not exceeded the operating temperature range.
