right elevation
The date of ex-factory on the certificate is indicated
enable us to effectively
Production of raw materials to users
Effectively track the situation
Bottom view
·Metal nickel plated base plate
·Surface mirror treatment, can be closely fit with the radiator for easy heat dissipation
·The bottom plate is isolated from all terminals, the insulation voltage is 2500VAC
Features
·Adopt modular technology, integrated thyristor chip, thyristor phase shift control circuit, pulse transformer isolation drive module
·Built-in power supply (for simultaneous sampling), no auxiliary power supply is required
The module sets 0-5V, 0-10V, 4-20mA three control signal input methods, and can also be directly controlled with a potentiometer
· There is RC absorption circuit in the module, you can not use external RC. It is better to add it in case of large current inductive load
With power LED indication and working status LED indication, intuitive and easy to use
Equipment suitable for controlling resistive load, inductive load and capacitive load Control signal terminal adopts pluggable/removable terminals, which is convenient for regular maintenance of equipment
Phase shift control angle can be smoothly adjusted from 180 degrees to 0 degrees
Module “OFF” is the control terminal for forcibly shutting down the output signal. When the control voltage greater than 2.5V is applied, the output voltage is forcibly turned off. With the development of electronic technology now, it can be connected with external control systems such as computer equipment to realize various intelligent control and host management, which is very suitable.
The control signal input terminal is completely isolated from the power supply terminal; the bottom plate is completely isolated from the control terminal and the main circuit; the isolation voltage is above 2500VAC, which is safe and reliable to use
Encapsulated with epoxy resin, effective against dust, moisture, corrosion and vibration
Modular design, strong anti-interference ability, and easy to install
Application range
Temperature control of heating elements such as nickel chromium, iron chromium aluminum, far infrared heating elements, silicon molybdenum rods, silicon carbon rods, etc.
Temperature heating control of salt bath furnace, industrial frequency induction furnace, quenching furnace and molten glass.
Rectifier transformer, power regulator (pure inductance coil), magnetization/demagnetization regulation, DC motor control, transformer primary or secondary voltage regulation control
Welding machine, resistance welding machine, spot welding machine control and other adjustment occasions. ·Synchronous motor excitation control, turbo generator excitation control, etc.
·Fan and water pump speed regulation energy-saving control, charging equipment control
Copper wire annealing equipment, power supply adjustment for nondestructive testing, etc.
The main parameters

Phase shift range: 0-180 degrees,
Input control signal mode:
Three control signal input modes of 0-5V, 0-10V, 4-20mA are integrated, users can choose according to their own needs, and can also directly connect a 10K potentiometer for control
Working frequency: 47-60HZ
Working environment: the temperature is -25 to 75 degrees and the maximum relative humidity is 90%
Insulation voltage: 2500VAC
Dimensions: length 114*width 76*height 46 (mm)
Note: If there is a phase requirement, if the wiring is strictly according to the above application diagram, the correct phase solution is very simple. You can start without tangling with the phase problem. After connecting the drive output and the power supply as the above application circuit, check the wiring and connect it correctly. Power supply, and then short-circuit the “0-5V” and “+5V” terminals of the control signal input terminal. After the work indicator is on, the volume output voltage is the maximum (if a load is connected, a light bulb can also be connected as a load), then The phase is correct; if the “0-5V” terminal and the “+5V” terminal are short-circuited and there is no output voltage or the voltage is very small, it means that the phase is not correct. Just swap the two lines of the power supply (and synchronization signal) input terminal on the module
