Three-phase full-bridge 50KW / 380V digital electromagnetic heating controller describe a product an electrical specifications, rated voltage and frequency: three-phase four-wire, AC 380V / 50Hz; 2, voltage range: 310V ~ 430V; 3, rated power: 50KW (digitizes the conditioned power 30% -100%). Second, the ability to adapt to an environment temperature: -20 ℃ ~ 50 ℃; 2, humidity: ≤95%. Third, an overview of the basic performance, voltage and power characteristics: constant current input (380 ± 10% V); 2, to ensure that the load is heated to about 400 degrees between the input power is not less than 85-95% of rated power; 3, Thermal efficiency ≥90%; 4, IGBT module overheating protection temperature: 85 ℃; 5, the operating frequency: 15-30KHz; 6, AVR microcontroller based digital phase shifter automatic tracking control; 7, the use of water and wind double cooling structure; 8 Industry-wide bridge main circuit design; 9, digital stepless power; 10, a powerful open application platform, without the coil is not suitable, the user can set parameters to control various application purposes; 11, can be equipped with electrical programming Easy operation panel monitor or control; 12, can provide high-end users of digital LCD operation panel; 13, the use of advanced digital phase digital phase-locked loop control technology, IGBT work in zero voltage turn, zero current shutdown state, effectively reduce IGBT losses, a revolutionary user fried solve the problem long plagued the module; 14, using industrial components, 100% high temperature aging tests to ensure long-term reliable operation 24 hours at 50 ℃ industrial environments; 15, can be set to run work Time, time is completed automatically shut down, enter the password before boot, you can change the password; 16, with full electrical isolation soft start heating / stop mode, convenience and temperature controller is connected; 16, a heating coil short circuit, open circuit, phase loss, overheating 17, 485 can be connected to the computer through the industry, remote monitoring and centralized control of the host-OFF;;, overcurrent, overvoltage protection function 17, can be customized according to customer demand for personalized features; 18, using Fuji IGBT module dedicated drive; 19, using the world famous Infineon IGBT module; 20 support 0-5V PID control power input interface, you can control the output power of the linear operating state; 21, industrial-quality design, work simultaneously on the same barrel 10 or more interfering, high-reliability applications; 22, MTBF of 10,000 hours. Fourth, the system wiring instructions: 1, the chassis behind the A, B, C, received a three-phase line of fire, N zero line, L1 and L2 receive coil; 2, LED external lights, random matching an external 12V indicator, users can connect You can not answer; 3, R / S connected thermostat output (normally open interfaces, while not yet reached the working temperature, the closed state; when the temperature to stop working, handling off-state); 4, supporting both random factory air plugs, used to access the R / S terminal and an external LED lights; 5, the coil mounting options: Mica big 25mm2 hot line or two parallel lines 16 square around a length of about 35 meters, cotton insulation thickness of about 15-20mm (yes refers to the high-temperature measurements with tight cloth). V. Installation Notes: 1. When installing the controller, pay attention to the fan inlet and outlet, make sure ventilation, do not put hot air into the machine. 2, the external coil wire is not too long, usually takes about 1-3 meters on each side, too long, the power will be less than optimal results. 3, when multiple controllers to work together from the coil and the coil to keep your 50mm or more, there may appear too close not working properly, the work process a "squeak ... squeak ..." sound is normal a. 4, when multiple controllers to work together, the coil wire is best not tied together, it is best placed separately, and be careful not to water. 5, when the product is found to water or moisture, please stop using, can be used to clean up the rear. 6, regularly clean up the dust on the fan controller, it will greatly improve the life of the product.
