It is mainly divided into ATS and STS. STS static toggle switch STS (Static Transfer Switch), also known as static transfer switch. The STS automatically switches to the second channel to supply power to the load after the first channel fails.

First, the characteristics are different 1. Limit switch: The limit switch has the characteristics of small size, multiple functions, high precision, adjustable limit, strong versatility and easy maintenance, installation and adjustment. 2. Proximity switch: The proximity switch has the characteristics of a limit switch, and at the same time has the sensing performance.

1. The circuit breaker is equipped with an arc extinguishing device, so the circuit breaker can be operated with load, but it cannot operate the current of the load. The disconnector does not have an arc extinguishing device, and it can operate places where the load current is less than 5A, but it is generally not suitable for operation with load. 2. And the circuit breaker ...

1. The air switch is an important electrical appliance in the low-voltage distribution network and power drive system, which integrates control and a variety of protection functions. In addition to completing contact and breaking circuits, it can also generate short circuits to circuits or electrical equipment. Protection against severe overloads and undervoltages, etc.

First, first place the dual power supply on the adjustment table, and the phase wire and the neutral wire (neutral line) are docked in place, and can not be connected wrongly. Second, after the line is connected, it is necessary to check the installed line, and then turn on the main switch of the debugging station to turn on the common and standby working power supply. Three, when the double ...

1. After opening, establish a reliable insulation gap to separate the equipment or line that needs to be overhauled from the power supply with an obvious disconnection point to ensure the safety of maintenance personnel and equipment. 2. According to the operation needs, change the line. 3. It can be used to divide and combine small currents in the line, ...

In the design of switching power supply, the physical design of the PCB board must be proper, otherwise it may cause excessive electromagnetic interference and lead to unstable power supply. 1. The design process from the schematic diagram to the PCB should be rigorous and perfect: the establishment of component parameters ...

1. First open all the packages of the newly bought limit switch, confirm that the parts in each package are not missing and complete, and then discharge all the parts in turn. 2. Then open the body part of the limit switch, as long as you loosen the screws with a screwdriver.

1. Change the reference current of the feedback module Regulating the reference current is the most basic way to regulate the output current of a switching power supply, and it can usually be achieved by rotating a potentiometer or toggling a switch. Changing the reference current allows the magnitude of the feedback current to be compared with it, so as to control the switch ...

1. Common air switch models in the family Common family models: DZ series, C16, C32. C40, C80, C100, C120 and other products, of which C represents the starting current, such as: C32 means that the starting current is 32A, which can drive a 6500 watt water heater, C40 ...

The socket, lamp head, kitchen, bathroom, refrigerator, air conditioner of each route should be put out separately, and each route should have a separate air switch, high-power rooms, such as kitchens and bathrooms, the line of more than 4 square millimeters should reach 20A, and the general lamp head line should only be 16A, and each line ...

The so-called PNP and NPN proximity switches are for the type of DC three-wire proximity switch output transistor, and even though many proximity switch output stages use MOS transistors, they are still called the same. Differences: PNP type proximity switch: The type of proximity switch output transistor is P...

1 The contact is overheated Contact heat is mainly caused by the current flowing through the contact, and there is power loss between the contacts (such as contact resistance loss, arc energy loss). It is normal for the contacts to heat up, but severe heat (overheating) is a malfunction. The main ...
