Four-connector control box

Control box overview: The control box is widely used. Its AC is 50HZ and the rated working pressure is a low-voltage power grid system with AC voltage of 380V. It can also be used in power systems with AC 50HZ and voltage below 500V for fire pump control, submersible sewage pump control, fire fan control, fan control, lighting distribution control, etc. The control methods include direct control start, star-delta step-down start control, auto-coupling step-down start control, frequency converter start control, soft start control and other start methods.

Purpose and performance

The control box is suitable for factories, mines, enterprises, shopping malls, hotels, schools, airports, ports, hospitals, high-rise buildings, living quarters and other places, AC 50HZ, rated working voltage AC 380V low-voltage power grid system, as power, lighting distribution and It is used for motor control and is suitable for indoor wall-mounted and outdoor floor-standing power distribution equipment. It is also used in power systems with AC 50HZ and voltage below 500V as fire pump control, submersible pump control, fire fan control, fan control, lighting distribution control, etc. The control methods include direct start control, star-delta step-down start control, and auto-coupling. Various control methods such as step-down start control, frequency converter start control, and soft start control can also be used. Isolating switches and fuse-type switches can also be used as isolation breaking points. Generally used atlases include 99D303-2 standard atlas for commonly used fans and 01D303-3 standard atlas for commonly used water pumps. The main body of the chassis is made of high-quality aluminum alloy profiles, which has the characteristics of solid structure, beautiful appearance, and good heat dissipation performance. It is widely used in instruments, instruments, electronics, communications, automation, sensors, smart cards, industrial control, precision machinery and other industries. It is a high-end The ideal box for instruments and meters. Aluminum alloy is made of pure aluminum with some alloying elements added, such as aluminum-copper alloy, aluminum-zinc-magnesium-copper superhard aluminum alloy. Aluminum alloy has the characteristics of light weight,

low cost, mechanical properties (uniform strength), easy processing and high heat dissipation. In particular, the vehicle engine part is particularly suitable for the use of aluminum alloy materials. As for most computer cases, aluminum-copper alloys are used. Mainly considering the heat dissipation issue. Because after copper and aluminum are mixed and extruded, its heat dissipation performance is very good, and even some high-end CPU water-cooling fans also use this material. If it is for military use, the first choice is to ensure solidity, and aluminum-zinc-magnesium-copper superhard aluminum alloy is the first choice.

normal usage conditions

1. The ambient temperature is not higher than +40℃, the average temperature within a 24-hour period is not higher than +35℃, and the lower limit of the ambient air temperature is -5℃;
