True Color LCDAC variable frequency regulated power supply adopts panel knob adjustment design, which can quickly and accurately set voltage and frequency parameters. The knob operates smoothly, and the adjustment process is continuous without jumping. It can not only realize rapid parameter switching through large angle rotation, but also complete small value calibration, taking into account the convenience of operation and adjustment accuracy. |
Pure hardware controlThe AC variable frequency regulated power supply adopts pure hardware control circuit design, abandoning the traditional CPU control mode, and eliminating the risk of power outage caused by processor failure, program running or logic error from the root. The circuit constructs stable control logic through discrete components, which has fast response speed and strong anti-interference, and can continue to operate reliably even in complex electromagnetic environments. |

Protection functionThe AC variable frequency stabilized power supply is equipped with an all-round protection mechanism, covering output overvoltage, overcurrent, overload, overtemperature and short circuit protection. It can monitor the power supply state in real time, trigger the protection action immediately in case of abnormality, and quickly cut off the output to avoid equipment damage. At the same time, the sound and light alarm function is linked to feed back the fault state synchronously through light flashing and sound prompt, so that the operator can detect and handle it in time. |
Product ApplicationAC variable frequency regulated power supply is widely used, covering the R & D, testing, production and debugging of industrial and civilian products such as household appliances, LED lamps, motors, compressors, electric tools, etc. At the same time, it is suitable for experimental power supply of scientific research institutions, voltage frequency adaptation of import and export equipment, and precision power supply requirements in the aerospace field. |
