Rectification effect test device

one. Overview:

The rectification effect test device is designed and manufactured for GB7000.1-2007/IEC60598-1:2003, Appendix C, Appendix C, metal halide lamp and high pressure sodium lamp abnormal circuit test requirements, it can meet the above standards The requirements of the test of the abnormal circuit.

Second, the panel description:

1. Power supply: power supply button of ammeter and exhaust fan, power supply after pressing;

2. Diode connection knob: There are three gears to choose from, which are “0”, “1”, “2”. When screwed to “0” terminal, it means no diode is loaded, and it is rotated to “1” end, indicating that the diode is loading forward. , screwed to the "2" end, indicating that the diode is reverse loaded;

3. Ammeter: displays the electrical parameters of the power supply of the test sample;

4. Overload protection: the switch of the adjustable resistor, the resistor works only when it is closed, and there is short circuit protection;

5. Input terminal: the connection port of the variable resistor, that is, the A and B terminals in Figure 1;

6. Resistance adjustment handwheel: Turn this handwheel to adjust the size of the resistor;
