Product Overview High-voltage rectified DC power supply is a special power supply equipment that converts alternating current into high-amplitude DC voltage output. The output voltage is usually in the thousands of volts to hundreds of kilovolts, and the output power ranges from hundreds of watts to tens of kilowatts. Its core function is to provide stable, low-ripple DC power for loads that require high-voltage DC bias or power. Different from conventional DC power supply, the core technical difficulties of high voltage rectifier DC power supply lie in the design of high voltage insulation, the control of electric field homogenization and the limitation of output energy storage. When the output voltage reaches tens of kilovolts, air insulation can no longer meet the requirements and oil insulation is required.

Product Overview The high-current rectifier DC power supply is a high-power DC power supply equipment designed for industrial electrochemistry and special smelting scenarios. The core feature is the large output current capability (usually from thousands of amperes to hundreds of thousands of amperes) while maintaining a low output voltage. Its basic working principle is: three-phase alternating current after the rectifier transformer isolation step-down, by the thyristor or diode rectifier devices into adjustable DC output, through the same phase reverse parallel or module parallel technology to achieve a balanced distribution of current. Unlike conventional DC power supplies, the core technical difficulty of high-current rectifier power supplies lies not in voltage regulation, but in oversized

Product overview Periodic commutation (bipolar) lead pole rectifier power supply is a special DC power supply equipment that can automatically or manually change the polarity of the output DC during work. Its core function is to automatically switch the positive and negative polarity of the output terminal according to a preset time period or control instruction, so that the load (such as the workpiece in the plating tank) is alternately in the anode and cathode state. The power supply is mainly for those in the electroplating industry that have special requirements for coating density, adhesion and uniformity. In the process of periodic reversing chromium plating, electrolytic degreasing, alkali copper rolling plating, de-plating, etc., the periodic alternation of positive and negative polarity can be effectively changed.

Product Overview IGBT high-frequency switching power supply is a new generation of DC power supply equipment based on high-frequency PWM pulse width modulation technology, using insulated gate bipolar transistor (IGBT) as the core power device. The basic working principle is as follows: three-phase alternating current is converted into smooth direct current after rectification and filtering, and then converted into high-frequency alternating current (usually 10kHz to 50kHz) by IGBT full-bridge inverter circuit. After step-up or step-down isolation by high-frequency transformer, the final rectifier filter outputs stable DC voltage or current. Compared with the traditional SCR phase-controlled power supply, IGBT high-frequency switching power supply will work from the frequency

Product overview DC remote power supply system is a remote power supply system that transmits and receives DC power over a long distance through power cables. The system consists of two parts: local end equipment (near-end machine) and remote end equipment (remote end machine): the local end equipment boosts and converts the AC or -48V DC in the machine room into high-voltage DC, and transmits it to the remote end through photoelectric composite cable or power cable. The remote end equipment then converts the high-voltage DC step-down into the standard voltage required by the load (such as DC48V, AC220V, etc.), provide stable and reliable power supply for remote communication equipment or external field equipment. This technology fundamentally solves

Product Overview The AC long-distance power supply system is a professional power supply equipment for remote AC power supply designed for highways, communication base stations and other scenarios. The system consists of two parts: the local-end machine (isolated power generator) and the remote-end machine (isolated power converter). The standard AC power in the local-end machine room is boosted to the high-voltage AC power of hundreds of volts or even thousands of volts by means of boost-transmission-buck, which is remotely transmitted to the remote end through the power supply cable, and then the remote-end machine is stepped down and stabilized to the standard AC voltage (such as AC220V) required by the load equipment, provide stable and reliable AC power for remote devices.

Product Overview Single-phase variable frequency power supply is a high-precision AC power supply equipment using IGBT/PWM pulse width modulation technology, which can convert mains (single-phase 220V/50Hz) into pure sine wave alternating current with independent adjustment of voltage and frequency. Its core value is that it can simulate the power grid voltage and frequency standards of various countries in the world (such as 110V/60Hz, 220V/50Hz, 240V/50Hz, etc.), and provide a flexible and reliable power supply environment for the R & D, testing and quality verification of export electrical and electronic products. Different from ordinary regulated power supply, the output voltage of single-phase variable frequency power supply (0

Product Overview: The power-specific inverter is a highly reliable uninterruptible AC power supply device designed for power systems such as power plants, substations, and power supply bureaus. Its core function is to convert the DC power supplied by the DC distribution panel (DC 110V or DC 220 V) into a pure sine-wave AC output (AC 220V or AC 380 V), thereby providing a stable and reliable power supply for critical loads in the power system, including remote control, communications, monitoring, relay protection, and emergency lighting. This product supports two operating modes: AC primary (mains priority) or DC primary (inverter priority), with automatic switching achieved via a static transfer switch.
