This version of
The controller has the possibility to change parameters and read them using UART port.
It is able to heat and cool without changing any jumpers. It has also open collector output which allows to use it as
Its small size,
The controller operates in PWM mode (Pulse Width Modulation) and can control currents of up to 8 A. For the temperature sensor, it uses a P0K1.202.3FW.B.007. By default, the temperature setpoint is set to 20 degrees Celsius.
Due to the possibility to set the parameters of a PID controller, the driver can be adapted to almost any system. Depending on the inertia of the system,
In normal work (when
When SJ1 is soldered/shorted user gets control on the regulator. Using PC and USB->RS232 TTL it is possible to send and read parameters to/from the regulator. To this end just use the GND, TXD and RXD outputs. To read
The current flowing through the Peltier cell depends on the supply voltage used. Most of the common modules should be supplied with the voltage of 12 to 15V, and the maximum current that flows through them is defined by a cell symbol. For example, the 12708 symbol means that the cell should be supplied with the voltage of 0 to 12V, and a maximum current which can be used amounts to 8A.
Recommendations and requirements
We recommended the use of power cables with
The system detects a lack of connection with a thermistor and then switches WARNING LED on. As long as the connection is lost, the driver will not take any action and the open collector output is grounded. When measured temperature is back to Tmin/Tmax range, OC becomes disconnected and warning diode is OFF
If the temperature is higher than 45 degrees Celsius, WARNING LED starts to blink but the driver is working normally.
If the temperature is higher than 70 degrees Celsius, WARNING LED is ON and driver will not power the Peltier module.
