SCR power controller,power regulator Overview SCR power regulators are widely used in different power regulation equipment in the industry, such as kilns, thermal treatment furnaces, electric heating furnaces, electroplating equipment, launching machines, extruders, high cycle machines, etc. The power regulators of the company are applicable to various kinds of equipment in different control modes to meet the requirements of clients. Features ·Sealed IC circuit boards of SCR power modules are used ·Full electronic safety devices (quicker than high rate fuses), in the time of passing current, it automatically cuts off the trigger devices to protect the controlled silicon. ·Exceptional interference resistance, capable of being used for transformer load, high frequency device earlier stage voltage regulators ·With current feedback applicable to negative resistance load such as silicon molybdenum rods, platinum heaters ·Capable of performing different control changes (e.g. fixing current and voltage) ·Easy for installation, not easy to be impacted, with high control accuracy Specifictions input signals Current input: 4-20mA DC, input impedance: 250Ω Voltage input: 1-5V Manual input: 5KΩ potentiometer Load rated voltage range 110V: 110V AC +/- 10% 50/60Hz 220V: 220V AC +/- 10% 50/60Hz 380V: 380V AC +/- 10% 50/60Hz 440V: 440V AC +/- 10% 50/60Hz Effective value current and refrigerating mode Compulsory air cooling mode: 40A, 60A, 80A, 100A, 160A, 200A, 300A, 400A Water cooling model: 600A- 1200A (special customization) Load connection mode and phase identification (3 phases) Load mode: triangular or star type center not to grounding. Phase shift range: 0-120o Phase identification: If R-S-T wiring is correct, then SCR controller phase identification neon lights are on Control mode Phase control voltage regulation type (non feedback type) Phase control voltage regulation type (current feedback type) Distribution type zero position control power regulation Electronic protection Protective action: When the current exceeds 130% of the rated current (adjustable), the input is disconnected and there will be damage to any parts. Alarm relay action Action time: <10ms Reset: Press Reset switch , power on/off Relay contact capacity: 250V AC 3A Radiator excess temperature protection system Protection action: When the temperature of the radiator exceeds 75°C, the output is disconnected Action time: <20ms Power restarts when the reset failure is removed Operation ambience Peripheral temperature range: 0 60°C, Peripheral humidity: 0- 90% RH Insulating impedance Minimum 20 MΩ 500VDC Insulating strength 2000VAC1 minute (220V) 25000VAC 1 minute (380V) Materials and external coatings Steel plate/ paint coatings
