Peltier controller

Product Summary

Peltier controller driver
TDC-1000A series One-channel digital temperature controller for Peltier devices.
The temperature converting unit, PID control unit, and bipolar constant current driver are integrated.C4
TDU-5000A(R/G) series
TDM-5000A(R/G) series 		DIN-sized one-channel digital Peltier controller driver. The temperature converting unit, PID control unit, and bipolar constant current driver are integrated in a compact body of 96 x 96 mm (DIN standard panel).
You can achieve temperature control of Peltier devices just by supplying a DC power. TDM-5000 with no display unit is also available.
TDC-1600 series One-channel digital temperature controller for Peltier devices.
The temperature converting unit, PID control unit, and bipolar constant current driver are integrated.
TDC-1640/1660 series The TDC-1640/1660 series are one-channel digital controllers for high capacity Peltier devices (1200W/1800W types).
The temperature converting unit, PID control unit, and bipolar high-efficiency constant current driver are integrated. You can achieve temperature control of Peltier devices just by supplying an AC power.
It achieves control stability of ±0.03℃ even though it is of a high power type.With an interface with a PC provided as standard, it can work with any type of system.
TDC-2000/4000 series (Peltier controller driver with a control accuracy of 1/100℃)
Highly accurate control is achieved based on the TDC-2000/4000 series.Overshoot suppression control is added with an easy-to-use interface.
TDC-2000/4000G series Highly accurate control of ±0.002℃ is achieved based on the conventional TDC-2000/4000R series.
The all-in-one TDC series includes a lineup of 9 models. A platinum resistance thermometer sensor, thermistor, or IC sensor (optional) can be used as a temperature sensor.
TDC-2000/4000R series (Two/Four-channel digital temperature controller)
The temperature converting unit, PID control unit, and bipolar constant current driver are integrated. An interface with a PC is provided as standard.
Controllers
LCD1600 Equipped with LD/Peltier control, it achieves high output of 300W each.
LCD2000/4000
(Two-channel LD controller) 		It can perform LD current control (ACC) and LD temperature control (PID). An interface with a PC is provided as standard.

Peltier controller selection method

Select a controller with a drive voltage that satisfies the 4 parameters (1. Voltage, 2. Current, 3. Power, and 4. Internal loss*) required for a thermo-electric (Peltier) module.

Allowable internal loss* (Pd) values for different models (per channel)TDC-1000A: 60W, TDC-2000: 36W, TDC-4000: 18W (per channel)

Is Current x Resistance (= Vt / It) (required for the thermo-electric (Peltier) module) 1/2 or less of the maximum drive voltage (Vc) of the controller?

If Yes:

Acceptable if (Vc-Vt) x It is Pd or less.
Example: Using a 5V6A thermo-electric (Peltier) module with TDC-1020
(15-5)×6=60W
→ It can be used because the allowable internal loss of TDC-1020 is Pd=60W

  • Pd（W）：Allowable internal loss
  • Vt（V）：Maximum rated voltage of thermo module (Peltier)
  • It（A）：Maximum rated current of thermo module (Peltier)
  • Vc（V）：Maximum drive voltage of controller
  • Ic（A）：Maximum drive current of controller

If No:

Acceptable if (Vc/2)² x (It/Vt) is Pd or less.
Example: Using a 12V10A thermo-electric (Peltier) module with TDC-1020
(15/2)² ×(10/12)=46.875W
→ It can be used because the allowable internal loss of TDC-1020 is Pd=60W.
