Current Calculation Formula
Single phase: SCR Current = 1.2*[(Load *1000)/Line Voltage]
Unit:
Current: A
Load: kW
Line Voltage: V
Main Loop Power Distribution
- NFB: The Power Supply can be cut off to avoid electric shock during repair and maintenance.
- MC: It can cut off the power supply to the load. When the power regulator fails or the temperature is too high, cut off the power to avoid burning the equipment.
- SCR: Adjust the output current according to the size of control signal to achieve the effect of temperature signal.
- Load: The load can be resistive load, inductive load, rheostat load, etc.
Control Terminal Function Description:
- P+ reference power supply +5V: A given reference for external potentiometers.
- A11 is the current analog input port 1: DC 0~20mA/DC 4~20mA (Input Impedance 125Ω) which forms input loop with GND.
- A12 is the voltage analog input port 2: 0~5V Input/potentiometer input (middle cap)/DC 0~10V which forms input loop with GND.
- GND is the Signal Common Ground for analog signal and switching signal terminal.
- SW1 is the external start/stop end. SW1 and 7 terminal GND constitutes start/stop, the regulator works when two terminals are closed and vice versa.
- SW2 is the external start/stop end with 7 terminal GND. If closed, select analog input port-2 if disconnected select analog input port-1.
- GND is the Signal Common Ground for analog signal and switching signal terminal.
- A is the RS485 Communication port +RS485.
- B is the RS485 Communication port -RS485.
- NO and COM Output relay to select a running output signal or alarm output signal, Load capacity AC240V/5A, DC24V/5A.
- SYNC is for power synchronization cable for details check main loop power distribution diagram.
- L, N is the control board power supply AC160-240V.
Note:
The SCR has no special slot for the power line earthing and it is not necessary to ground the power. But if users need to connect the ground, you may connect G wire at the mounting screw as shown in the below image.
