The product can limit the starting current of the asynchronous motor when it starts, and is widely used in electric fans, ...

Short-circuit maintenance is a function of equipment connected between the power supply and the load, which can effectively disconnect the short-circuit point from the power supply when the load side is short-circuited. If an equipment has a short-circuit maintenance function, it must have a certain short-circuit breaking ability; And a device with the ability to break in a short circuit ...

1. What are the factory recovery parameters of Reynolds inverter? N600 = 100 (often press the WR button for 3-5 seconds), it is necessary to be in the shutdown state to be effective. 2. In the parameters of the N308 motor of the inverter, is the [motor leakage inductance reactance] specified sub-leakage inductance or rotor leakage inductance react? Decide...

1. The constant pressure water supply of the inverter increases the comfort of water supply by 3 times 2. Constant water pressure, reducing pipe bursts and leakage by 80% 3. High efficiency and energy saving, power saving effect up to 20%-60% (depending on the actual situation) 4. The use of frequency converters can realize multi-point pressure in different time periods.

Inverter motor - used for special occasions with inverter, it is different from the general motor in that a strong cooling fan is added. And the power of the fan comes from the independent power supply, can not be from the main motor out of the line, the effect of the strong cooling fan is to ensure that the motor at low speed...

1. The cause of the leakage problem Some sites use frequency converters to control the motor, which will present the problem of leakage, and the leakage voltage ranges from tens of volts to 200 volts. In view of this problem, the reasons for this shortcoming are theoretically expounded and stated as follows. Depend on...

With the rapid development of China's national economy, the supply and demand situation of oil and gas resources is becoming increasingly severe, and the import of oil and gas is increasing year by year, so it is urgent to expand the field of domestic oil and gas exploration and development. Strengthening the exploration and development of shale gas resources can make up for the lack of conventional oil and gas resources and promote the sustainability of the oil and gas industry.

JJR8000 series of intelligent motor soft starter is the use of power electronics skills, microprocessor skills and modern control theory skills to produce today's international first-class starting equipment, the product can constrain the starting voltage of the asynchronous motor when starting, can be used in fans, water...

More than 40 sets of RNSVG series low-voltage power generator sets and RNZB series high-voltage reactive power automatic compensation devices designed and produced by Reynolds have been successfully completed and will be delivered in the near future. This product is owned by Shanghai Reynolds ...

1. Select varieties according to the above series according to the purpose and requirements of use Note that the main circuit load type is strictly differentiated, whether it is DC or communication. The communication contactor is different from the DC contactor, and is only suitable for DC-1 to DC-5 loads when used for DC loads.

Reynolds soft starter fault code Instantaneous stop -F 01 Instantaneous stop terminal 7 to terminal 10 open TOO LONG STARTING TIME -F 02 STARTING TIME IS TOO LOW AND THE STARTING TIME IS TOO LONG (GREATER THAN 60S) Overheating -F 03 Start too often, reduce the number of starts Input out of phase -F 04 ...

Frequency conversion speed regulation is to change the power supply frequency through the frequency converter, and then adjust the motor speed to improve the operation efficiency of the electric drive system. Depending on the current, VFDs can be divided into AC-DC-AC type and AC-AC type. At present, the most widely used in China is the AC-DC-AC type. ...

Overload can be different Servo drives generally have 3 times the overload ability, which can be used to overcome the inertial moment of the inertial load at the moment of start-up, while the frequency converter generally allows 1.5 times the overload. Handling precision Servo control ...

There are two types of inverter parking. One form is called "free parking". As the name suggests, it is to quickly "power off" the motor, so that the motor can slide and park by its own inertial force (OFF2 parking); The other form is called "brake parking". So this "brake parking ...

1. Maintenance objectives of overcurrent In the frequency conversion speed regulation system, there are two devices: the frequency converter and the motor. The degree of tolerance to overcurrent is not the same. The planners of the production machinery decide on the capacity of the motor based on the principle of heat. That is, as long as the electricity ...

In power distribution equipment such as voltage distribution cabinets and switchgear at all levels of power plants and substations, the conductors connected between large electrical equipment such as generators and transformers and various electrical equipment are called busbars. Busbars, also known as busbars, are used to collect, distribute, and transmit electrical energy. The connection methods of the bus bar are ...

1. The soft starter does not start and the fault-free code appears, perhaps because the control power supply is not connected, the solution is to check the power supply of the control power supply to see if the circuit connection is correct. 2. The motor starts when the motor announces a hum/no start signal, perhaps because of the thyristor/module ...

It is human beings who have always been committed to making human-computer interaction safer, easier to use, and more efficient, which has made collaborative robots gradually become the main stream of shopping malls. It is precisely because of the vigorous development of the collaborative robot industry that Synapticon Gmb ...
