IEC60990 Figure 4 Touch Current Measuring Network Convenient Safety test equipment

IEC60990 Figure 4 Touch Current Measuring Network, Convenient to Use​

Application:

This network is convenient to use and easy to operate, and the power supply switch is made separately, which can solve the shortcomings of power supply capacity of the previous machine and can test the more powerful products.

Applicable object:

1. Inspection of electrical products in the national entry exit inspection and Quarantine (commodity inspection) system;
2. The quality inspection department of electrical products under the state quality and technical supervision;
3. Electrical products certification institutions in Chinese mainland abroad.
4. Domestic social laboratories and certification institutions of electrical products;
5.  Inspection Department of foreign professional electrical appliance manufacturers;
6. Quality inspection department and production process quality control department of domestic professional electrical appliance manufacturers

Parameter:

Selection of materials and technology:

1. The resistor has the characteristics of high precision and high power, high voltage and low temperature drift resistor
2. The capacitor with long-term stable and reliable capacitance, high voltage resistance, non inductive, current shock resistance, microwave absorption performance and very small leakage current is adopted
3. The module steam injection adopts packaging solids with high pressure resistance, good high frequency characteristics and low dielectric loss. After pouring in the module, it has large heat capacity and enhances the ability to resist short-term impact current
4. In order to ensure the effective measurement of various components, the surface connection method is adopted, which can be disconnected from each other for the measurement of components; The surface shall be provided with effective component identification and wiring identification

Preparation:

Before testing, you need to prepare instruments as follow:
Oscilloscope x1

One or ten times the voltage probe x1
Power supply x1 (the test voltage or frequency that can be adjusted or changed to the required voltage or frequency)
