According to the operation needs, change the line. 3. It can be used to divide and combine small currents in the line, ...

Ambient air temperature: upper ambient air temperature +40°C; The lower limit of ambient air temperature is -5°C; The average temperature of the ambient air for 24 hours does not exceed +35 ° C. Altitude: The altitude of the installation site does not exceed 2000m. Atmospheric conditions: Atmospheric relative humidity at ambient air temperature of +4 ...

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 ...

First, the characteristics of the load switch A load switch is a switchgear between a circuit breaker and an isolation switch. It has a simple arc extinguishing device, which can cut off the rated load current and a certain overload current, but cannot cut off the short-circuit current Second, the classification of load switches According to the operating voltage ...

How to use the indicator color correctly? 1. The indicator light (also known as the signal light) is mainly used to attract the attention of the operator or instruct the operator to carry out a certain operation in the way of bright indication, and as an indication that a certain state or instruction is being executed or has been executed. 2. General ...

(1) The disconnector should have an obvious disconnection point, which is easy to identify whether the electrical appliance is disconnected from the power grid. (2) There should be reliable insulation between the disconnect points of the disconnector, that is, there should be enough distance between the disconnect points of the disconnector to ensure that it can work reliably under harsh climatic conditions, and ...

1. If it is installed on metal, a certain space must be ensured to avoid interference between the proximity switch and the metal other than the detection object, resulting in failure. The metal parallel to the sensing surface must be 3 times the sensing distance from the sensing surface. The metal around the shaft of the proximity switch must be outside the cylinder, close to ...

1. When the power is cut off for some reason and the power supply cannot be restored in a short period of time, the backup power supply must be enabled: (1) Cut off the circuit breakers of the mains power supply (including the circuit breakers of the control cabinet of the power distribution room, and the mains power cut-off of the dual-power switching box), and pull the double-cast anti-backing switch to the side of the self-provided power supply, ...

1. What is the reason why the empty trip cannot be pushed? 1. If the air opening itself is faulty or damaged, the air opening should be replaced with a new one. 2. If the line is caused by a short circuit, the line should be found first, and then reconnected.

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 ...

1. Buttons 1. Red Operation in hazardous situations. It is often used for emergency stops Stop and break. It is often used to stop all machines, stop one or more motors, stop a certain part of a piece of equipment, make the electrical components lose power, and have a stop function reset button. ...

1. The design is usually simple and straightforward 2. Works well in almost any industrial environment 3. It has high accuracy and repeatability 4. Low-power devices 5. High inductance load can be switched 6. Used to switch multiple loads 7. Simple installation ...

The meaning is different, the scope of application is different, and the role is different. Air opening C represents the current, and the D model represents the power. The scope of use is different. If it is a household electricity, the air switch of the C model is generally chosen. The role is different. Type C it is used for home lighting use, Type D is suitable for ...

1. Wiring The design requirements of wiring are very strict in the design of switching power supplies, and they must be done well to pass the test. If the designer does not handle the wiring work in the early stage of design, there will be great safety hazards in the future electricity consumption. So here I recommend you to buy a switching electric ...

1. Install the dual power transfer switch with the power supply to ensure the correct access of the power supply. 2. Adjust the handle of the dual power transfer switch to the "automatic" position, so that the power supply will automatically detect the state of the other power supply, when one of the power supplies fails, the other power supply will ...

1) Voltage Setting: Turn on the DC switch, adjust the voltage knob to adjust the voltage reading to the desired operating power connection. If you need to lower the voltage, turn the potentiometer slowly so that the drip rate of the voltmeter is compatible with the speed of the manual adjustment knob. 2) Constant Current Setting: Connect ...

Reduces EMI interference The metal shell is used as a shield to reduce the interference of external electromagnetic field radiation. To reduce electromagnetic interference from the power line input, an EMI filter is added to the power supply input. 　　At the output, capacitors with good high-frequency performance and low ESR are used The use of polymer solids ...

Uses: X42 series limit switches can be widely used in various types of mechanical equipment, automatic assembly lines and other light and medium load occasions, can detect the object action state, such as presence and absence, movement position, end of stroke, etc. Overview: The switch is mainly composed of switch operating parts, ...

1. The current value of the air switch is too low, and the load power is greater than the rated power of the air switch. 2. The load joint is not firm, and the joint is not compressed. 3. If there is a short circuit in the line, check whether the electrical plug is dry. 4. The line is aging and leaking, resulting in both the live wire and the neutral line.
