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|<=00C; 25% when 00C< |Td|<0.50C; 50% when 0.50C< |Td|<1C0; 75% when 10C< |Td|<1.50C; 100% when |Td|>1.50C. This method allows a uniform temperature control in the -50.00C to +70.00C Range, with 1/20C accuracy. As the name hybrid (Hy) implies, the desired temperature value is derived from a variable analog-voltage, while all other control-signals are digital. The desired temperature (Set-Temperature) value is adjusted by an on-board 25 turn trim-pot (P1). An onboard Red LED is used to monitor the Cooler Port #1 voltage, while a Green LED is used for the Cooler Port #2.  An Optional 9600 Baud Serial 2-Line by 16 Character LCD module is used to display Set and Measured Temperatures. This board requires a single 9V to 30V DC power source (unregulated and unfiltered) at a 0A to 32A current range to operate normally. A small (2.3”x2.4”x0.45”) finned integrated heat sink is included with mounting hardware (as shown on the photograph) to operate at 2x16A or 960W power level. Higher power-levels (30V, 2x20A or 1200W) can be achieved with more efficient heat-sinks. Please click on this link and read the Board Mounting Instructions and Heat Sink Selection Guide. Typical applications are: DC Resistive Heat Controller, Thermo-Electric Cooler Controller, etc. This board can be configured and programmed to perform efficiently in many customized applications.

Set-Temperature Adjustment with Trim-Pot P1:

The minimum voltage that trim-pot P1 can be adjusted to is 0.046V DC at pin I1 test point. This minimum voltage corresponds to -50.0 Degree C Set-Temperature. A typical operating temperature of +25.0 Degree C corresponds to 2.960V DC; while +70.0 Degree C corresponds to 4.69V at pin I1 test point. The slope of this linear temperature function is: 0.0391V/C. The factory pot setting is 25.0C.

A Typical Application of the Si5HyUdPTC2-CC-30V-2x16A

In this cooling application, the temperature of the enclosed environment is proportionally controlled by two TE banks (each in the 0 to 480W power range) and by the Si5 board. The desired temperature is linearly adjusted with the on-board trim-pot (P1) from -50.00C to +70.00C Temperature Range, in 1/20C Steps. The optional 9600 Baud Serial LCD (Displaying Set and Measured Temperatures) module can be ordered from Signal with the part number of Si14LCD2L16CH-3PC  (2x16 display with 12” cable and 3-pin connectors, and with back-light). The 9-bit digital temperature sensor can be purchased from us (as: Si18DTsens). The TE cells can be purchased from:  www.customthermoelectric.com/.  A wide variety of Linear and Switching Type of Power Supplies can be purchased from: http://www.mpja.com/powersupply.asp.  Warning:  The connecting wires to the Load and the Power Supply must be heavy gage copper wire (#12 AWG or heavier) to handle the rated current level. In addition, these heavy gage wires act as a heat sink, protecting the board from overheating.
