The Si5HyUdPTC1-CA9B-30V-10A is a 30V 10A, microprocessor based, Hybrid, Unidirectional, Proportional Temperature Controller board for Cooling Application. This controller uses pulse-width modulation (PWM) to efficiently control average current to a resistive heater or Thermo-Electric (TE ) cooler cell in 0 to 300W power range. 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 -250C to +1020C Range, with 1/20C accuracy. As the name hybrid (Hy) implies, the required temperature value (or load current) is derived from a variable analog-voltage, while the all other control-signals are digital. The desired temperature value (or load current) is set by an (0 to 5V range) external analog voltage (VI1,G), or by an external potentiometer. This analog (I1) input is zener-diode protected. This board requires a single 9V to 30V DC power source (unregulated and unfiltered) at a 0A to 10A current range to operate normally. An onboard LED (Green) is used to monitor the load-voltage. No heat sink is required (as shown on the photograph) to operate at 10A or 300W power levels. Higher power-levels (30V, 20A or 600W) can be achieved with heat-sinks. Please click on this link and read the Board Mounting Instructions and Heat Sink Selection Guide. Typical applications are: DC Resistive Heater Controller, Thermo-Electric Cooler Controller, etc. This board can be configured and programmed to perform efficiently in many customized applications.

 A Typical Application of the Si5HyUdPTC1-CA9B-30V-10A

In this cooling application, the temperature (load-current) is proportionally controlled (in the 0 to 300W power range) by the Si5 board and the desired temperature (or load current) is linearly adjusted (with an onboard 10-turn 5kW Trim-Pot); -250C to +1020C Temperature Range, in 1/20C Steps. The 9-bit digital temperature sensor can be purchased from us (see Parts Department Si18DTsens) or you can wire up your own using the Dallas Semi. Digital Thermometer chip DS18S20, in TO-92 casing (order from www.digikey.com as part number DS18S20-ND). An optional 2-Line by 16-Character serial LCD displays the Set and Measured Temperature Values on the CN4 Port (Si14LCD2L16CH-3PC).The TE cells can be purchased from:  www.customthermoelectric.com/. A simple unregulated DC power supply is shown below; wide variety of linear and switching power supplies can also be used with this board; click on www.mpja.com to find these supplies.
