TEC Controllers
-
Thermoelectric Controller DX5100 Series represents a precision-programmed devices of management of thermoelectric coolers.
Bi-directional (heating and cooling) PID regulation is realized. Four operation modes are integrated:
- Constant Temperature
- Constant Voltage
- T-regulation
- Temperature Program in time
Diagnostics of TEC is realized in the Thermoelectric Controller. The diagnostics includes the measurement of the TEC AC Resistance, Figure-of-Merit and time constant.
PID Auto-tuning is implemented.
Thermoelectric Controller is based on a Modular Concept. Controller is divided functionally and physically into the control board and the power board in two variants: single-channel and two-channel, as well as peripheral and additional modules - the indication board and the Interface board.
Modular concept allows assembling of OEM Controller Configurations from one- and two-channel up into a network systems up to 32 or 128 channels jointed by RS485. Every channel has an independent algorithm of work.
