Interpretation of high and low temperature humidity and heat test chamber

Author:QINSUN Released in:2023-06 Click:139

The high and low temperature damp heat test chamber is suitable for high and low temperature changes of parts and materials of electronics and electrical, automobile and motorcycle, automotive aerospace, rubber, plastic, metal, naval weapons, colleges and universities, scientific research units and other related products See below its various performance indicators.

The power supply voltage of this product should meet the three-phase five-wire system AC380V ± 10% 50 ± 0.5Hz; how to connect the test box to the power supply?

1. Before wiring the high and low temperature humidity and heat test chamber, it is necessary to confirm the wire diameter of the external power supply: whether the capacity of the main switch meets equipment requirements.
2. Use a multimeter to confirm whether the power supply voltage is normal (allowable deviation ±10%), the voltageIf there is no problem, turn off the main switch; 3. Connect the neutral wire (blue N wire) from the machine to the neutral wire terminal in the distribution box (the neutral wire must be connected correctly, otherwise the equipment will not work or burn electricity in the components);
4. Connect the ground wire from the machine to the ground wire terminal of the distribution box;
5. Connect the three R.S.T. phase wires from the machine to the three terminals at the lower end of the switch of the distribution box respectively, and make sure the screws are tight; Note: The high and low temperature damp heat test box is designed with phase sequence protection function. If the phase sequence is wrongly connected, the instrument will not be powered on when the machine ist lit. The position of the two lines can change the order of the phases, which meets the requirements of the test chamber.
