Temp controller provides easy access and data retrieval

The 5R7-570(A) open-board temperature controller features a proportional integral control algorithm to provide precise control to thermoelectric (Peltier effect) modules. The H-bridge control provides a seamless transition between heating and cooling to eliminate dead spots. It provides a green LED to indicate heat, blue for cooling mode, and simultaneous illumination of both to indicate the load circuit is off due to an open sensor.

Pulse-width modulation helps control the power level in the thermoelectric module at a base frequency of 1-kHz. It features ±250-steps power resolution in the load circuit control. The controller measures 1.75 x 3.5 X 3-in., has a 6 to 28-Vdc input voltage, a 0 to 36-Vdc output, a load current from 0.1 to 12.5 A, a 450-W output power control, control stability of ±0.1°C, and a temperature range from -20° to 150°C. The temperature controller suits aerospace, automotive, biomedical, defense, medical and semiconductor markets.
