Oven Industries 5R7-570(A) open board electronic temperature controllers

Oven Industries’ 5R7-570(A) RoHS-compliant open board electronic temperature controllers are designed with a proportional integral control algorithm to provide precise control to thermoelectric modules (Peltier) at an economical price.

The H-bridge temperature control provides a seamless transition between heating and cooling, eliminating dead spots. Green LED for heat and blue LED for cooling indicate mode and simultaneous illumination indicates the load circuit is off due to an open sensor. Pulse width modulation controls the power level in the thermoelectric module at a base frequency of 1 kHz. Power resolution is one of ±250 steps in the load circuit control. This small package temperature controller measures 1.75 x 3.5 Xx 3" with input voltage 6–28 VDC, output voltage 0–36 VDC, load current 0.1 to 12.5 A, 450 W output power control, control stability ±0.1°C and temperature range of -20 to 150°C.
