The RoHS-compliant 5R7-570(A) from Oven Industries is a open board temperature controller is specifically de-signed with a proportional integral control algorithm to pro-vide the most precise control to thermoelectric (Peltier effect) modules at the most economical price. The H bridge 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 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. Features Universal AC Input Isolated Power Supply PC Programmable RS232 Communication Port Setup via operator interface or serial link GUI Non-Volatile Memory Set temp range determined by thermistor type Open Circuit Protection Accessories Display Model 5R6-576: 4 digit LED temperature read out (A) with remote set temp pot and knob with dial scale Temperature Sensor Oven Industries
