The Si5HyUdPTC2-CC-30V-2x16A is a Dual 30V 2x16A, microprocessor based, Hybrid, Unidirectional, Proportional, Temperature Controller board with an integrated heat sink that uses pulse-width modulation (PWM) to efficiently control the average current flow in two TE (Thermo-Electric) cooling banks. The two banks are connected in parallel, and jointly controlled (turned on and off at the same time). The power flow in each bank is controlled from 0 to 480W power range with 4W steps. Two high-power (55V, 60A max.) MOSFETs are used (one for each cooling bank) to control the temperature of an enclosed environment. An onboard microprocessor allocates the load-power and controls the temperature. The sample temperature is measured by a small 9-bit digital thermometer Si18DTsens. This sensor uses a unique “1-wire interface” (with parasite power mode) that requires only 2-conductors for reliable remote (long as 20 meters) temperature sensing. The term proportional controller implies that the value of the average load current used is proportional to the difference between the actual and desired temperature. Five PWM duty-cycle values are used depending on the absolute-value of the difference between the set and measured temperature values (|Td|). The duty-cycle is 0% when |Td|<=0C; 25% when 00C< |Td|<0.5C; 50% when 0.5C< |Td|<1C; 75% when 1C< |Td|<1.5C; 100% when |Td|>1.5C. This method allows a uniform temperature control in the -25C to +102C Range, with 1/2C accuracy.
