1. Features
The TEC-600W-36V-5VIN is a high-power density TEC temperature controller with a maximum load of approximately 36V16A and peak power of 576W. This controller allows direct parameter adjustment, which can be saved for standalone operation. Real-time temperature control is achieved through parameter setting and temperature monitoring via a built-in display.
2. Controller Specifications
- Input Voltage: AC220V
- Output Voltage: -36.0V to +36.0V
- Rated Current: 13A
- Peak Current: 16A
- Indicator Output Current: Less than 50mA
- Temperature Sensors: Various 5V-output transmitters, including PT100, PT1000, and thermocouples (T, K, C, S types)
- Control Temperature Range: -20ºC to +100ºC
- Communication Interface: RS485 with magnetic isolation
3. Wiring Diagram
- 220V Cable: Connects to the AC220V mains.
- Output Terminal (PCB): Connects to the controlled TEC semiconductor.
- When heating control voltage is output, the display shows a positive proportion (1-100%), with red as positive and black as negative.
- When cooling control voltage is output, the display shows a negative proportion (-1% to -100%), with red as negative and black as positive.
- Temperature Sensor: 5V-output transmitter connected via XH2.54 terminal, collecting TEC temperature.
- Note: The sensor must be tightly attached to the TEC cold side to ensure precise control.
- Communication Interface: RS485 terminal (XH2.54), including 485+, 485-, and GND (3 wires).
- The RS485 communication section features electrical isolation for enhanced adaptability.
- 485+: RS485 positive output, high level at 5V, low level at 0V.
- 485-: RS485 negative output, high level at 5V, low level at 0V.
- Communication protocols are customizable.
