Electrical appliances need voltage regulators for reasons

1. There is a problem with an inverter, it cannot operate and the LED shows "UV" (abbreviation of under voltage), which clarifies that the alarm in the book is under voltage of the DC bus. Because the power supply of the control loop of this type of inverter is not taken from the DC bus, but from the AC input through the transformer alone.

The type of inverter is selected according to the type of production machinery, speed regulation range, static speed accuracy, and starting torque requirements, and it is most appropriate to decide which inverter is the most suitable to use. The so-called suitability is not only easy to use, but also economical, to meet the basic conditions and requirements of technology and production. ...

1. When the stabilized power supply is powered on, please do not disassemble the stabilized power supply or pull the input and output cables of the stabilized power supply at will to prevent electric shock or other electrical safety accidents. 2. The input and output connections of the regulated power supply must be reasonably arranged, ...

Product Introduction With optimized open-loop vector control, V/F control, closed-loop vector control, stable function, function optimization, it is a high-function vector inverter, which can be widely used in speed control accuracy, torque echoing speed...

Delixi 3P air switch, additional current 630A, additional voltage 380V. The Icu=Ics=70kA of this circuit breaker. When the short-circuit current reaches 70kA, can the circuit breaker still be used? Assuming it works, the ICU is now at its limit, which is paradoxical. Assuming it can't be used, Ics is 70KA, clarifying ...

(1) The drawing of the wiring diagram and the wiring table shall be subject to the request of GB6988.6-1993 in the "Production of Control System Function Table Diagram". (2) All electrical components and wires should be marked with letter symbols and wiring numbers that differ from those in the schematic diagram of the electrical circuit. Schematic diagram catalog number, final ...

Delixi solid state relay and Delixi communication contactor are more used products, so what are the advantages of solid state relay relative to communication contactor, how should we choose when we can choose? 1. First of all, the solid ...

The so-called DC-DC is actually DC to DC voltage, of course, LDO is also a kind of DC-DC, and only LDO can only achieve step-down. The general DC-DC is mainly converted from DC to AC communication through the self-excited vibration circuit inside, so the external inductance and capacitor are required to achieve LC vibration (and LDO is only ...

Application of air switches (circuit breakers). Delixi air switch, also known as circuit breaker. It is a switch that actively closes as soon as the current in the circuit exceeds the additional current. Air switch is a very important electrical appliance in the low-voltage distribution network and electric traction system.

1. Check and tighten all terminals to prevent serious heating caused by loosening. 2. Conduct a comprehensive view of the input (including output) terminal, rectifier module, inverter module, DC capacitor and fast-melting devices, and the parameters ...

The first method is that you can analyze what the cause is according to the condition displayed on the inverter, such as whether the faulty code appears normal, whether there is still running code or not, and still nothing appears (in the case of input power), which means that there is a rectification problem. If you're on standby...

Product Introduction With optimized open-loop vector control, V/F control, closed-loop vector control, stable function, rich functions, it is a high-performance vector inverter, which can be widely used in speed control accuracy, torque echoing speed, ...

(1) Fault characteristics a) *** tripping may occur during operation, but if it is restarted after resetting, it often trips as soon as the speed rises. b) has a large inrush current, but most drives can already be tripped, maintenance without damage. Due to the ...

1. How to disassemble the voltage regulator Generally, there are screws on the shell of the voltage regulator, please disconnect the power supply first, and then remove all the screws on both sides to take off the shell. After the regulator shell is disassembled, the circuit, copper coil, carbon brush, etc. inside will be revealed.

1. If the fuse is burned out, please approve the load equipment as soon as possible, make repairs in time, and restore power; 2. If you use a fixed amount of fuse, please use a regular line, and do not match it at will, so as not to cause ...

What is the difference between Delixi voltage regulator SBW and SJW, which is better? Customer Question: I maintain an uninterruptible power supply and a computer server, and the whole community shares a transformer, so the voltage fluctuation may be greater during the day and at night.

1. It can reduce the impact on the power grid, and there will be no problem of excessive peak-to-valley difference. 2. It can speed up the controllable function, and then speed up the slipping according to the needs of the user; 3. The abort mode of the motor and equipment is controllable, ...

1. The divider is the sixth generation of intelligent machine using microcomputer chips, and the intelligent program is very high. 2. Single-phase three-phase connection, the divider on the market is scored as A, B, and C three-phase wiring for three-phase electricity, which is not only inconvenient for installation, but also prone to phase sequence errors. 3. Can ...

1. Cooling fan (2-3 years) As long as the inverter is in use, the cooling fan has always been running, so the cooling fan is generally a short-service life accessory, generally after the use of the cooling fan for 2-3 years, the bearings, balls, motors, etc. of the fan are seriously worn, and they need to be replaced.

When the VFD is viewed regularly, the power supply should be blocked, the operation of the VFD should be stopped, and the cover of the VFD should be removed. The first thing is to check the places that cannot be seen without downtime, or the places where it is difficult to find problems on a daily basis, as well as the inspection and adjustment of electrical characteristics. After blocking the VFD power supply, the main power ...
