Control box for factories and mines, enterprises, shopping malls, hotel, hospital, schools, airports, ports, high-rise buildings, living community and so on occasion, ac 50 hz, rated voltage of ac 380 v low voltage power grid system, as power, lighting power distribution and motor control, suitable for indoor wall-mounted power distribution equipment, outdoor floor installation. Also used in ac 50 hz, voltage up to 500 v power system as the control of fire pump, submersible pump, fan control, fire control, fan control, lighting distribution control is used, the control mode has a direct start control, star triangle step-down start control, since the lotus root step-down start control, inverter start control and soft start control, all kinds of control mode, isolating switch, fuse switch can also be used as isolation points the breakpoint. There are 99d303-2 standard drawings of common fans and 01d303-3 standard drawings of common water pumps.
Production of various control boxes, reasonable design, moderate price, excellent reputation. The main body of the case is made of high quality aluminum alloy profile, which has the characteristics of strong structure, beautiful appearance, good heat dissipation performance, etc. It is widely used in the fields of instrument, instrument, electronics, communication, automation, sensor, smart card, industrial control, precision machinery and so on. Aluminum alloy is made of pure aluminum with some alloying elements, such as aluminum - copper alloy, aluminum - zinc - magnesium - copper superhard aluminum alloy. Aluminum alloy has the characteristics of light weight, low cost, mechanical (uniform strength), and aluminum alloy is easy to process and has a high heat dissipation. In particular, car engine parts are particularly suitable for the use of aluminum alloy materials. As for computer cases, most are made of aluminum-copper alloy. It's all about heat dissipation. Because copper and aluminum are extruded together, their heat dissipation performance is quite good, and even some high-end CPU water-cooling fans use this material. If it is military, the first choice is to ensure the firmness, aluminum - zinc - magnesium - copper super - hard aluminum alloy is the first choice.
Normal operating conditions
1. The ambient temperature is no higher than +40℃, the average temperature within the 24-hour period is no higher than +35℃, and the lower limit of ambient air temperature is -5℃; 2. The air is clean, and the relative humidity should not exceed 50% when the temperature is +40℃. Higher relative humidity is allowed at lower temperatures, such as 90% at +20 ° c, allowing for occasional moderate condensation due to temperature changes;
