Product Description

As long as a signal: (a variety of control signals are input: DC 4-20mA, DC 1-5V, DC 0-10V, 10K potentiometer), the best linearity can be given.Regulating and regulating temperature. It can directly trigger two unidirectional thyristors below 150A. The control board is composed of imported high performance single-chip microcomputer as control, operational amplifier, pulse transformer and so on. It can be used in conjunction with all kinds of automation instruments, no interference to instruments, or manual control with external potentiometers. It is widely applied to control systems with continuous smooth adjustment of load requirements, high accuracy or large current impact. Such as AC and DC motor speed control, voltage regulation, charging and so on. Mainly used for single-phase resistive load, inductive load or single-phase transformer primary side control, such as silicon carbide, silicon molybdenum rods, the resistance wire, can be used for the single-phase or two-phase full bridge controlled rectifier, has triggered and reliable, high precision, stable operation, the advantages of flexible use.

1. overview

The single-phase thyristor trigger board is composed of integrated trigger circuit, operational amplifier, pulse transformer and other units produced by the company. can

With all kinds of automatic instruments, there is no interference to the instrument and the manual control of the external potentiometer. It is widely used in the load requirement. A control system with high precision or no large current impact is made by continuous smooth adjustment. Such as AC and DC motor speed control, voltage regulation, charging Electricity and so on. Mainly used for single-phase resistive load, inductive load or single-phase transformer primary side control, such as silicon carbide, silicon molybdenum rods, resistance wire etc., It can also be used in single phase or two phase full bridge semi controlled rectifier, which has the advantages of reliable trigger, stable work and flexible use. Main technical parameters of 2. single-phase thyristor phase-shift trigger 1. The high performance imported single chip microcomputer is used as control, with good waveform symmetry, small DC component, good linearization, high control precision and stable work. 2. The working voltage is wide. The input line voltage can be as low as 4% of the rated voltage, and its control precision is basically unchanged. 3. The trigger power is large, it can trigger the thyristor below 150A directly, and also trigger the large current trigger plate. 4. The wiring is simple and the maintenance is convenient. 5. A variety of control signal input: DC 4-20mA, DC 1-5V, 10K potentiometer, 6. The design of the board is novel and unique, without the need for external synchronization transformer and no phase sequence restriction. 7. The main circuit and control circuit are completely isolated, safe and reliable. 8. The single-phase integrated phase shift trigger module provides control signal for the AC and DC load. This module is designed by single chip microcomputer. It is suitable for any SCR triggering. Arbitrary load can be adjusted stepless. It can realize the speed regulation of AC and DC motor. The original side voltage regulating, welding machine, temperature control, excitation, electroplating, and water of the transformer Reason. 9. Dimensions: 55mm (long) x 48mm (wide) x 40mm (high)
