Two, model description:
Three. Technical parameters:
Four, product application:SSR.YHR series solid state voltage regulator is composed of a silicon controlled switch circuit and resistance capacitance phase-shift circuit, eliminating delay circuit, overvoltage absorption circuit in the form of modules, using flame retardant engineering plastics shell, epoxy resin, self lifting screw crimping junction, with structure of high strength, impact resistance, vibration resistance, novel structure equipped with safety protection cover, make the installation convenient examination is safe and reliable when using only one potentiometer can realize AC power regulation, can replace the heavy touch regulator in many applications.Five. Typical applications:1, temperature control of industrial equipment 2, incandescent lamp dimming, 3 resistive heating element 4, conveyor speed control, 5 small AC motor speed control for Series 6, and other automatic power regulating occasionsSix, inappropriate occasions:1, 2 AC motor control, three-phase motor control applications, need to complete 3 sine wave input 4, output 5 to zero, can not afford by the phase modulated waveform of RF interference occasions are capacitive load and rectifier circuitSeven, safety precautions:1, the output is a thyristor phase modulation waveform, which will produce radio frequency interference (the series of inductance in the load loop, can reduce interference). 2, please use the longer control potentiometer wiring wire with shield or shield metal tube; 3, the product is non isolated (input and output), isolation selection potentiometer should pay attention to and the line voltage, the installation process must be Caution!; 4, the load current is higher than 5A must use or installation of radiator the metal plate has a corresponding cooling effect, and the solid pressure regulation device and a mounting surface between the radiating bottom plate coated with thermal grease. In 5, the use of inductive load, high transient voltage and surge current is applied and output, it may lead to solid state voltage regulator misconductions or damage, usually require voltage control devices with special clamp voltage at the output terminal access, such as bidirectional zener diode or pressure sensitive resistor (MOV). Varistors recommend 1.6-1.9 times the rated voltage. 6, close to the smaller minimum load current load current load, load must be in parallel with a virtual load resistance, residual voltage to reduce output leakage current at high load on. 7, in order to avoid the solid state relay temperature rise exceeds the allowable value, the design of application should be considered when the heat dissipation and the installation position, when two or more solid state relay installed side by side, should have the appropriate spacing. 8, if there are special requirements and application, please contact with the technical department of our company, in order to obtain more detailed technical support.
