How to properly connect the programmable high and low temperature test chamber switching power route

Programmable high and low temperature test chamber is used to test the characteristics of raw materials in a variety of natural environment machinery and equipment and to test a variety of raw materials high temperature resistance, low temperature resistance, dry resistance, moisture
resistance.
Suitable electronic devices, household appliances, communications, dashboards, cars, plastic products, metal materials, food, organic chemistry, decorative building materials, diagnosis and treatment, aerospace engineering and other handicraft inspection quality inspection
.
Programmable high and low temperature test chamber is suitable for testing various main technical indicators
of electronic and electrical engineering, cars and motorcycles, aerospace, vulcanized rubber, plastics, metal materials, pictures of ship weapons, parts and raw materials of colleges and universities, scientific research and other related commodities under the condition of high and ultra-low temperature transformation 。 The working voltage of the switching power supply of this commodity needs to consider AC380V±10% 50±0.
5Hz three-phase five-wire system; How to connect the test chamber to the switching power supply? 1.
Before wiring the programmable high and low temperature test chamber, it is necessary to check the wire diameter of the external switching power supply: whether the volume of the main gate is in line with the regulations of the machine and equipment; 2.
Use a digital multimeter to check whether the working voltage of the switching power supply is normal (allowable error±10%), the working voltage in the middle of the phase line is 380V, and the middle of the phase line and the neutral line is 220V, after everything is normal, close the main gate; 3.
Receive the wire connector of the equipment to the wire terminal of the power distribution cabinet; The zero line of the equipment is received on the neutral line terminal in the power distribution cabinet, and the zero line must be connected, otherwise the machine and equipment cannot work or burn electrical components; 4.

The three phase wires are respectively received on the three terminal blocks of the web end under the main gate of the distribution cabinet, and ensure that the screws are tightened; Note: Programmable high and low temperature test chamber design scheme will phase sequence maintenance function, if the phase sequence is inserted wrong, when starting, the dashboard will not be easy to plug, need to be under the distribution cabinet main gate WEB end three phase wires, at will replace the parts of the two lines, you can change the phase sequence, in line with the provisions of
the test chamber.
