Reynolds EPS emergency power supply routine maintenance

First, select from the inverter "software". The reason why the factory chooses the inverter to work together with the fan is that it is hoped that the automation and intelligent design of the inverter technology can improve the speed regulation mode of the fan, and reduce the wasted energy consumption, which not only improves the wind efficiency.

Reynolds JJR5000 series all-digital intelligent AC motor soft starter adopts power electronics technology, microprocessor technology and modern control theory technology, and is a new type of starting equipment at the international advanced level. This product can effectively limit the starting current of asynchronous motor start-up, and is widely used in ...

Most of the applications of frequency converters (hereinafter referred to as -VFDs) are primarily due to the fact that VFDs can change the output frequency and thus change the speed of the motor. If the frequency of the VFD cannot be adjusted and no damage is found on the hardware, it can be considered that the maximum output torque of the VFD is less than the load progress torque ...

1. Technology: (PC or PLC) is used to make the equipment complete the intelligent constant pressure variable supply water supply according to the requirements of water supply and fire protection; 2. High efficiency and energy saving: the system can set the pressure according to the demand, and the system actively adjusts the speed of the pump and the number of pumps according to the set pressure, so that the equipment can run in ...

Under the current production conditions, when the inverter is used to form an automatic control system for control, in many cases, it is necessary to choose PLC and inverter to match the use, such as bearing cleaning, packaging paper printing, PCB board production, etc. PLC ...

Water pump inverter pressure conditioning steps: 1. Open PID closed-loop control; 2. Close the pressure circuit; 3. Set the pressure feedback and set the given pressure; When the pump speed is changed, the outlet pressure can be changed. Adjust the operating frequency of the VFD. The higher the frequency, the higher the pump speed and the higher the pressure. About ...

A frequency converter is a power electronic device that can change the frequency of an AC power source to control the speed and output power of a motor. Inverters are widely used in industry, aviation, metallurgy, petroleum, chemical industry, electric power and other fields.

When the high-power motor starts, the current is large, which will cause the grid voltage to be seriously shaken, in order to deal with this problem, the general requirements for speed regulation are not high, and the soft engine can be used to reduce the voltage and start. However, the drop in the starting current when the step-down is started will also make the starting torque drop significantly.

Soft starters and frequency converters are two completely different products. The inverter is used in the local area where speed regulation is required, and its output not only changes the voltage but also changes the frequency at the same time; A soft starter is actually a voltage regulator, which is used when starting a motor, and the output only changes the voltage and does not change the frequency. Change...

Low pressure issues The VFD reports a low voltage issue when the drive's DC link voltage drops below 62% of the nominal level at the high setting (480 Vac) and 50% of the nominal value at the low setting (400 Vac). The +10% and -15% voltage tolerances in most manuals are the ones that claim to be ...

As an electronic electric, the inverter itself also consumes electricity (about 3-5% of the additional power). A 1.5 hp air conditioner consumes 20-30W of electricity, which is equivalent to the length of a lamp. The inverter works under the power frequency and has the function of saving electricity, which is practical. But the conditions are: At the top of the list, great success ...

1. What are the factory parameters of inverter rehabilitation? 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, [motor leakage inductance reactance] is the specified sub...

Reynolds inverter brochure (partial) 　　Before installing When unpacking, it is found that the machine has water or left water traces, indicating that the inverter has been flooded, so please do not install and use it. When unpacking, it is found that the machine is damaged and deformed or the parts are missing, please do not install and use it, otherwise there will be fault expansion and personnel ...

We need to ensure that the capacity of the inverter is matched. First of all, according to the nature of the load, the correct selection of the type of inverter. When selecting the inverter, the current value of the actual motor should be used as the basis for the selection of the inverter, and the rated power of the motor can only be used as a ...

Reynolds soft starters include soft starters for high, medium and low voltage motors, including JJR1000 series, JJR2000 series, JJR5000 series, and RNB3000 series frequency converters. Reducing the starting power supply avoids voltage drops and voltage dips in the power supply. Smooth start-up avoids product damage. ...

1) The air duct of the inverter cabinet should be planned reasonably, and the exhaust should be clear and smooth, so as to avoid the formation of vortex in the cabinet and the accumulation of dust in a fixed direction. 2) The top air outlet of the inverter cabinet should be equipped with a protective top cover to avoid debris from falling directly.

Generally, most motors start to speed up from 0Hz, but in some special cases, it is necessary to start directly from a certain frequency. At this time, the frequency output of the VFD at the moment of activation is the activation frequency. In general, you need to set the activation frequency in the following situations. ...

The system power is equal to the product of the power of a general-purpose inverter and the power of the motor. As long as both work efficiently, the system power will be higher. From the perspective of power, when choosing VFD power, you should pay attention to the following points: VFD ...

Now many electrical appliances are advocating the use of small parts, because small parts will not occupy space, and small parts can be moved and overhauled at any time, and the inverter also has a small inverter, how to buy a small fan inverter? Power picking ...
