| The main characteristics of intermediate frequency power supply are as follows:
First, the advanced repeated start function, to achieve the successful start of the intermediate frequency power supply, the start mode adopts the form of its self-excitation in the form of sweeping frequency zero voltage soft start, in the whole start process, the frequency regulation system and current, voltage regulation shut down system, time tracking load changes, to achieve the ideal soft start, this start mode has little impact on the SCR, It is beneficial to prolong the service life of SCR, and has the advantages of easy start of light and heavy loads, especially full furnace and frozen furnace can be easily started.
The control circuit adopts the microcomputer constant power processing circuit system, plus the inverter Angle automatic adjustment circuit, in the process of operation will automatically monitor the voltage, current, frequency changes, and thus judge the load changes, will automatically adjust the load impedance match, to achieve constant power output, Thus to achieve the purpose of saving time, saving electricity and improving power factor.
Three, perfect design, to promote the reliable work of the circuit because the control circuit uses CPLD software design, its program input is completed by the computer, its pulse precision is high, anti-interference, reaction speed is fast, convenient debugging, with the interception, voltage interception, overcurrent, overvoltage, undervoltage, lack of phase, water shortage, and other protection functions, because the circuit components always work in a stable range, Thus greatly improve the service life of the equipment.
Four, the equipment can automatically judge the three-phase line phase sequence, without distinguishing A, B, C phase sequence, debugging is very convenient.
Five, the program used the software imported from the United States, the production of the circuit board all using the crest automatic welding, no virtual welding phenomenon, all kinds of adjustment systems using contact-free electronic adjustment, no fault point, the failure rate is very low, the operation is very convenient.
Vi. High frequency equipment saves energy obviously, and the power grid pollution is small.
If power supply manufacturers for the user needs to produce IF power supply products. Welcome the need for intermediate frequency power supply users call to order!
