KH1-B single-phase closed-loop flip-flop
The introduction of foreign advanced IC dedicated SCR phase trigger output trigger pulse with high symmetry and stability, not change with the ambient temperature, no phase sequence requirements contained complete phase, overcurrent, overtemperature fault protection; high precision, fully functional, easy to use, reliable, and easy to debug, anti-jamming, etc. It can be widely used in various areas of industrial voltage and current regulation for resistive load, inductive load, transformer primary. Side and various rectifier devices which are mainly used in power supply, AC and DC voltage, salt bath furnace, frequency induction furnace, hardening furnace, the temperature of the molten glass and a variety of industrial furnace heating control; rectifier transformers, transfer workers machine, furnace transformer primary side, magnetizing demagnetization adjustment, DC motor speed control, single-phase motor soft start saving devices; temperature nickel, iron, chromium, far infrared heating elements and molybdenum silicon rods, silicon carbide heating elements and other control and many more.
Second, the performance characteristics
• no phase sequence requirements limit, can be used for power supply of 220V and 380V power frequency 50 / 60Hz grid.
• with various domestic and international control instrument (temperature controller), the output signal of the microcomputer direct interface.
• Suitable for a variety of load types resistive load, inductive load, transformer primary side and the like.
• With soft start soft stop function (start time is adjustable), to reduce the impact of interference on the power grid, so that the main circuit is more secure.
• driving ability, each channel can output 800 mA of current, can drive 4000A SCR.
• fault alarm output. (External buzzer and lights)
• emergency stop function.
• pressure limiting function.
• Over-current protection function end.
• temperature protection function end.
• With all-pass function control terminal.
• open loop closed loop two control modes, and there are two pulsed operation, applied to different loads.
• Integrated Structure: Set the power, synchronous transformer, trigger control circuit, pulse transformers in one played tight structure, easy to debug, simple wiring.
Third, the major technical indicators and use
Input signal: 4-20mA (select short jumper S1 by P1) DC 0-5V (P1 jumper selectable by shorting S2) DC 0-10V (select S3 by shorting jumper P1) 10K potentiometer (manual adjustment Time)
Output Specifications: single-phase or two-phase two-way trigger 0-100% output.
Phase shift range: 0-180.
Trigger capacity: ≤4000A SCR (SCR).
Indicator: DS1 ¤ PC board working power indicator
DS4 ¤ fault indication (OFF)
Power use: AC1 and AC2 access to 220V or 380V mains power, when the input 380V ac sure to select the input through JP11 jumper, otherwise it will damage the transformer (220V input choose the factory).
Load testing: test triggers are not connected to the load current is less than 0.5A or less, SCR does not work so please load currents greater than 0.5A..
