General Specifications

Item EMU938, EMU1238 EMU1225
Insulation Resistance After continuous operation at normal ambient temperature and humidity, the measurement value between the input terminal and the frame is 100 MΩ min. using a 500 VDC megger.
 
 		 After continuous operation at normal ambient temperature and humidity, the measurement value between the lead wire and the frame is 100 MΩ min. using a 500 VDC megger.
 
 
Dielectric Strength No abnormality is observed even with an application of 1.5 kVAC at 50 Hz between the input terminal and the frame for 1 minute after continuous operation at normal ambient temperature and humidity.
 
 		 No abnormality is observed even with an application of 2.5 kVAC at 50 Hz between the lead wire and the frame for 1 minute after continuous operation at normal ambient temperature and humidity.
 
 

For the alarm type only, no abnormality is observed even with an application of 1.5 kVAC at 50 Hz between the power-supply lead wire and the alarm lead wire for 1 minute after continuous operation at normal ambient temperature and humidity.
 
 
Temperature Rise After continuous operation at normal ambient temperature and humidity at maximum air flow, when temperature becomes constant, the measurement value of the winding temperature rise using the thermometer method is 30 °C max.
 
 		 After continuous operation at normal ambient temperature and humidity at maximum air flow, when temperature becomes constant, the measurement value of the winding temperature rise using the thermometer method is 35 °C max.
