Foshan Ran Chi electromagnetic half-bridge heater now entered the fourth generation of goods - Digital electromagnetic induction heater, compared with the previous two generations of this paragraph merchandise goods has improved significantly, electromagnetic heating control board with 16-bit full digital DSP chip, the circuit is more simple , computing faster, more precise control, handling and maintenance more complete. Movement structure designed cooling effect is good, the movement now all use the white shell, beautiful appearance. Technical parameters: Working voltage: AC320V-AC420V working frequency: 12KHZ-22KHZ Working current: 15KW (23A) 20KW (30A) 25KW (37A) coil inductance: 15KW: 110UH-130UH 20KW: 80UH-100UH 25KW: 70UH-90UH temperature line: 15KW: 16㎡ line 30 meters (reference value) according to the actual on-site commissioning, whichever 20KW: 16-20㎡ line 28-29 meters (reference value) according to the actual on-site commissioning, whichever 25KW: 25㎡ line 26-27 meters ( reference value) according to the actual on-site commissioning, whichever Foshan Ran Chi 15KW-25KW digital Half Bridge Interface Description Interface clarify electromagnetic heater 1, the control board power input: This port access from the DC voltage rectifier bridge rectified, about 530V, polarity (are marked), positive and negative do not reversed. 2, Hall (optional) / high-frequency transformer access side: If accurate measurement of current and constant function, the demand access to current sensor (4Pin); 2Pin the right of access to the high-frequency transformers. Attention must not take the wrong pin. 3, the module driver side: drive pin access modules have polarity; 4, Maintenance terminal: the positive terminal of the DC voltage three-phase rectified; 5, fan power connection Imports: communication fan power input terminal, an access communication 380V; 6, fans mouth one / two: Connect 380VAC plug fan; 7, digital appear Interface: 5PIN plug connected to digital; 8, power adjustment rheostat (optional): demand pick adjustable resistance power adjustment to be customized; 9 thermocouple / infrared interface (optional): Connect thermocouple or infrared sensor, to be customized; 10, the module heat sink temperature sensor: connect the heatsink temperature sensor plug, no polarity; 11, wire coil temperature sensor: Connect measuring line plate temperature sensor plug, no polarity; 12, thermostat switch interfaces: Connect the thermostat switch connector can also be connected to the general switch for manually initiated and closed, short circuit then start work, stop the job off.
