New Open Board Digital Temperature Controllers
The 5R7-570(A) RoHS compliant open board electronic temperature controllers are specifically de-signed with a proportional integral control algorithm to provide the most precise control to thermoelectric modules (Peltier) at the most 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 1Khz.
Power resolution is one of ±250 steps in the load circuit control. This small package temperature controller 1.75" x 3.5" X 3" with input voltage: 6 to 28VDC, Output Voltage: 0 to 36VDC, Load Current 0.1 to 12.5 Amps, 450W output power control, control stability: ± 0.1°C and temperature range of -20 to 150°C.
