The product adopts the company’s fifth-generation digital processing platform technology, an open application structure, and a wide inductance adaptation coil Range, through the digital programmable control system can achieve special functions for different customers, different occasions, bringing customers Great convenience, it is the preferred product for electromagnetic heating reconstruction project and supporting heating equipment.

1, Connect the power supply voltage of the cooling fan, but connect the 220V power when the fan is 220V, and connect the 380V power when the fan is 380V
2, Connected with cooling fan 220V / 380V (depending on the user, generally 380V)
3, When the external cooling fan is DC 24V, this interface is a switch that controls the 24V fan to work or stop. The two ends of the interface are actually the normally closed contact points of the relay output on the motherboard.
4, Dual AC 24V power supply (choose 4 or 5 when making half-bridge)
5, Dual AC 24V power supply (choose 4 or 5 when making half-bridge)
6, Single AC 16V power supply
7, Power indicator (red)
8, Work indicator light, flashing during standby, and always on (green) during work
9, External indicator light, led to the LED interface outside the chassis
10, The soft start interface is connected to the R / s interface outside the chassis (can be set to open or close work through F-20, factory default close work, open stop status
11, Finely adjust the power potentiometer. When there is a large deviation in power, this potentiometer can be adjusted appropriately.
12,32-bit high-speed DSP processor
13, Externally connected programmable operating display
14, Isolated RS485 communication interface
15, External load temperature detection interface 1, with an accuracy of ¡À 1 ¡ã C (maximum 150 ¡ã C) single-channel, default 1 is used to measure external working temperature
16, External load temperature detection interface 2, with an accuracy of ¡À 1 ¡ã C (maximum 150 ¡ã C)
17,Multi-function input interface (set by F-20)
(1)10K input for external connection potentiometer can adjust the power range from 20% to 100%
(2)Externally connected PID input (0 ~ 5V) input
Do infrared thermometer or thermocouple conversion voltage 0 ~ 5V input to achieve the display temperature and control power size (up to 1000?C can be measured and displayed)
18, Connect the high-frequency Mutual inductor and pay attention to the direction. If the direction is reversed, the power is very small
19, IGBT module drive (when doing half-bridge, choose 19, 20 or 23, 24)
20, IGBT module drive (when doing half-bridge, choose 19, 20 or 23, 24)
21, Connected to high voltage DC bus
22, IGBT temperature sensor interface
23, IGBT module drive (when doing half-bridge, choose 19, 20 or 23, 24)
24, IGBT module drive (when doing half-bridge, choose 19, 20 or 23, 24)
25,Connected to high voltage DC bus
26,RS485 communication interface, connect A ,B
27, Externally connected K-type thermocouple
28, Externally connected 12V relay drives other required loads, synchronized with the fan start/stop of the machine
