Three-phase thyristor power regulator uses digital circuit to trigger thyristor to achieve voltage and power regulation. Adopt voltage regulation phase angle control mode, power regulation has fixed period power regulation and variable period power regulation two ways.
Power regulator in use may encounter inaccurate reference voltage, this time to check to adjust the power regulator to manual state, gradually increase the output. Observe whether the ammeter grows linearly. Load without pressure, load can not be added. In this case, we need to check whether the power supply, load, etc., is normal. In addition, it is possible to encounter abnormal operation phenomenon, the possible causes are too high ambient temperature, long-term load overcurrent, etc.
When the power regulator is in use, it will generate internal heat. Please install vertically and leave a gap on both sides to avoid bad heat dissipation and damage to the power regulator. The control box should have air convection vent. Install ventilation holes or exhaust fans based on the bottom-up principle of hot air.
Avoid installation in places with severe moisture or acid, alkali and corrosive gases. Do not install in a place with high temperature or poor ventilation. Environment — 10-45; Ambient humidity: lower than 90%RH(no condensation). When the power regulator is idle for three months, please dust the surface before running the machine. Regular maintenance, dust, oil pollution and many other phenomena may cause short circuit.
High efficiency, no mechanical noise and wear, no spark, fast response, small size, light weight and so on. The power regulator consists of a trigger plate, professional radiator, fuse, fan and housing. The machine has all the functions of the control board. By precisely controlling voltage, current, and power, the power regulator enables precise temperature control and, through its advanced digital control algorithm, optimizes the efficiency of power use and saves power.
The power-saving principle of the power regulator is well understood, such as industrial electric heating circuits, which control the opening and closing of the heating tube. Ac contactors or solid state relays are commonly used, but they are on and off while working. This repetition is constant at constant temperature.
The power regulator uses the digital circuit to touch the thyristor to realize voltage and power regulation. Voltage regulation adopts phase-shifting control mode, power regulation is divided into fixed period power regulation and variable period power regulation. The control board is equipped with phase-locked loop synchronization circuit, slow start and slow stop after power-on, heat sink overheating detection, current limiting protection.
Power regulator is a phase shift closed-loop power controller. The output trigger pulse has a high degree of symmetry and stability, and does not change with the ambient temperature. No adjustment of pulse symmetry and limitation is required during use. Field debugging generally can be completed without oscilloscope. Widely used in various industrial areas of voltage and current regulation. Suitable for resistive load, inductive load, transformer primary side and all kinds of rectifier devices.
