[Note]

*1. All tests are measured using a constant-voltage supply unless otherwise specified.

*2. Thermal Detector temperature (+145°C±5°C) indicates the value at unusual operation, therefore, does not indicate

the guaranteed value at usual operation.

Thermal Detector is PRF18series (AS characteristic) manufactured by MURATA.

*3. The output noise voltage is peak value of an average-reading meter with a rms value scale (VTVM).

A regulated AC supply (50Hz) should be used to eliminate the effects of AC primary line flicker noise.

*4. Allowable time for load short-circuit and output noise voltage are measured using the specified transformer power

supply. About the load short circuit, it is designed assuming protecting by cut-off within 0.3 second.

*5. Weight of 1 HIC : 17.2g Outer carton dimensions (W×L×H) : 502mm×247mm×282mm
