4-channel, high-precision temperature controller for bidirectional KPI control of Peltier elements (heater/coolers)
The PR0202 temperature controller represents a precision designed system for managing Peltier elements with bi-directional (heating/cooling) KPI control. The diagnostics contains measurements of the TEC resistance and of the time constants with integrated KPI autotuning. The controllers are based on a modular concept and are equipped with a powerful processor. The sub-division is functional and physical into control board and power board with two variants: Single-channel and two-channel as well as peripheral and other modules – such as the display board and the optional USB interface board.
The modular concept enables OEM controller configurations from single-channel to two-channel systems up to networks of from 32 to 128 channels linked by the RS485 interface. Each channel has an independent TEC control and its own work algorithm.
