From the perspective of skills alone, the control method of the low-voltage inverter also indicates its skill portal to a certain extent. Here, we've broken down the following manipulation methods: 1. Sinusoidal pulse width modulation Sinusoidal Pulse Width Modulation (SPWM) is characterized by the simple structure of the control circuit, the cost of ...

The contact orientation is 100% secure As for the circuit breaker, the indication of the handle can also be said to be the fault indicator of the circuit breaker, if it is "blurred" for a while, it may cause irreparable damage. Therefore, according to the requirements of the national standard, in any case, the hand of the circuit breaker ...

Create a high-quality circuit breaker for secondary power distribution EZD molded case circuit breaker is a product series of molded case circuit breakers specially designed for secondary power distribution, especially suitable for secondary power distribution, civil construction market and mechanical and electrical market.

1. Selection of detection diode Point-contact germanium diodes are generally used for detection diodes, such as 2AP series. When selecting, the detection diode with high operating frequency, small reverse current and large forward current should be selected according to the specific requirements of the circuit. Although the detection and rectification of ...

There are many novices who are not familiar with the fake load when repairing the inverter, and the repair of the inverter saves many of their modules with the false load, because the novice repairer generally does not know how to do this, and now the light is on to make it clear that the module is going to be broken. A false load is a resistor with a few hundred ohms ( ...

1. Check whether the appearance of the inverter is in good condition, including whether the indicator light is running normally, whether the task control function of the operation panel is complete, and carefully observe the appearance of the inverter in the operating state, and do the corresponding recording work; When repairing the inverter, check whether the voltage value and current value exceed the allowable ...

1. The ATV32 inverter reports that the bLF is a brake control fault. Possible causes: 1. The brake release current is not reached. 2. When the braking logic control is assigned, only the closing frequency threshold [brake closure frequency] (bEn) is adjusted. Repair measures: 1. Check the inverter/electric ...

1. NSX series is Schneider's high-end molded case circuit breaker, with the best performance in all aspects, and of course, the price is also the most expensive. 2. CVS series, which is the main series of Schneider, has the second best performance compared with the NSX series, but can meet the vast majority of applications, and the price is more affordable. 3 ...

(1) Problem--: Contact deviation Phenomenon 1: The direction of the finger does not coincide with the mouse arrow. Reason 1: After installing the driver, there is no vertical contact with the bullseye center when calibrating the alignment. Deal 1: Correct the position from the beginning. Phenomenon 2: Some districts ...

1. Save capital contribution Focus on central function (true color LCD, serial communication interface, USB connection, Ethernet interface, etc.) 2. Save space Compact structure planning, only 38mm thick The fuselage is reserved for communication wiring ...

1. The power supply voltage of the secondary load is 0V. There is no response after the inverter is powered on, there is no indication on the operation display panel, and the 24V and 10V voltages of the measurement and control terminals are 0V. Check that the charging resistance or pre-charging circuit of the main circuit is correct, which can be identified as a switching power supply fault. The overhaul process is as follows: 1 ...

Beijing, China, April 6, 2022 – Recently, the list of "Red Dot Planning Awards", known as one of the world's three cutting-edge industrial planning awards, was grandly announced in Germany.

How it works Contactor refers to an electrical appliance that uses a coil to flow through an electric current to generate a magnetic field, so that the contact is closed, and then the load can be controlled. Because it can quickly block the main circuit and frequently connect with the equipment of the high-current control circuit, it has been used in electrical engineering.

1. After the inverter is repaired, the power number demand is corrected, don't forget Generally, an inverter corresponds to a power number (also known as the number of horsepower), for example, a 75 kilowatt inverter is set under heavy load, and 100 kilowatts is set under light load. In this way, the customer will not use it to present ...

The quality of UPS power supply devices directly affects the long-term operation of the UPS system in the future, especially the large and medium-sized UPS power supplies, so the large and medium-sized UPS power supplies should be standard in the process of planning to the device.
