IEC60335-1 clause 11 Hot Windind Temperature Tester Double Channel

product introdution

This instrument is based on IEC60335-1 clause 11 Household and similar electrical appliances-safety-Part 1:General requirements. It can replace the traditional way of bridge measurement, to measure its thermal resistance of winding or coil under the live work situation of motor, transformers, relays and other electrical products. With the characteristic of high speed, high precision, convenient operation and safety, directly display temperature rise etc., thus avoiding complicated operation and measurement errors caused by interruption of power supply, especially the hot tracking function cannot be matched by any traditional method of temperature measurement. It is widely used in various household appliances (such as air conditioners, refrigerators, electric fans, washing machines, etc.) and other small power motors and transformers for winding temperature measurement.

This instrument uses a microcomputer as the core, cold resistance, cold resistance ambient temperature, thermal resistance, thermal resistance ambient temperature, temperature rise, time experiment showed at the same time. Overall circuit has the characters: novel, unique and practical structure design, high integration, stable and reliable, shell with standard cabinet, light and beautiful, it can be used both in the laboratory and on site measuring.

Technical Parameters

1.The maximum test voltage: General is 380V AC; it can not exceed this value when using; test current: specified when ordering (Or capacitance box index). General is 15A, it can not exceed this value when using.

2.Winding temperature coefficient can be set from 0 to 999.9, all off the setting parameters will be saved when power failure.

3. The printing interface is 25 pins parallel port, it can be external drive with dot matrix printer or an inkjet printer

4.Power supply:According to customer country's voltage and current.

5.Operation environment: Temperature from 0℃ to 40℃, Humidity of less than 90%.
