20KW electromagnetic heater a half-bridge, a product electrical specifications, rated voltage and frequency: three-phase four-wire, AC 380V / 50Hz; 2, voltage range: 310V ~ 430V; 3, rated power: 20KW (digital adjustment of 30% - 100% power). 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, based on the AVR microcontrollers advanced digital phase shifters, digital lock automatic tracking control; 7, industry-wide bridge The main circuit structure design; 8, digitized stepless power; 9, a powerful open application platform, users can set a variety of application parameters control purposes; 10, can be equipped with electrical control programming or simple operation panel display; 11, high-grade Users can provide digital LCD operation panel; 12, using the most advanced digital phase digital phase-locked loop control technology, the IGBT in a zero voltage turn, zero current shutdown state, effectively reducing IGBT losses, a revolutionary resolve Users fried long plagued the problem module; 13, using industrial components, 100% high temperature aging tests to ensure long-term reliable operation 24 hours at 50 ℃ industrial environments; 14, you can set the running hours, the count-up automatically shut down, Enter the password to boot, you can change the password; 15, with full electrical isolation soft start heating / stop mode for easy connection with the temperature controller; 16, a heating coil short circuit, open circuit, phase loss, overheating, over-current, over-voltage, etc. protection; 17, you can connect via Industrial 485 computer, remote monitoring and centralized control of the host-OFF; 18, can be customized personalized features according to customer demand; 19, using Fuji dedicated IGBT module drive; 20, world famous Infineon IGBT module; 21 support 0-5V PID control power input interface, you can control the output power of the linear operating state; 22, industrial-quality design, to work simultaneously on the same barrel 10 or more non-interfering, high-reliability applications ; 23, 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 Aviation plug cable, used to access the R / S terminal and an external LED lights; 5, the coil mounting options: Mica hot line is greater than 10mm2, about 50-55 meters in length, cotton insulation thickness of about 15-20mm (refers to the use of high temperature After the cloth tight measurement). 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.
