TEC1-12706 Thermoelectric Cooler Peltier 12V 60W 92Wmax














Rated voltage: 12v 
Rated current of 4.5A, 
Power :50 - 60W 
Maximum temperature: 60o Celsius 
Dimensions: 4x4x0.4cm 

Connected to a 12-volt power supply the cell will have a temperature differential between the two sides of about 20oC(68oF). 
Important: do not connect the cell to a power supply for more than a few seconds without a heat-sink on the hot side otherwise there will be internal overheating and destruction of the Peltier cell. 

Installation 
This cooling Peltier cell is very simple to install and use. 
Before installation, you must provide a dry environment and allow for any condensation from the cold side to drain away and not to come in contact with the operating cell. 
Connect the two leads of the Peltier cell to an appropriate power supply and importantly, observe the correct lead polarity and attach an adequate heat-sink with a quality thermal conducting grease applied to the warm side of the cell; you will feel the warm side and the opposite cool side of the operating cell. It is important to identify both the correct lead polarity and the cooling/heating sides of the device. 
If you want a greater cooling differential, it is recommended to use two Peltier cells, namely, one stacked above the other with the hot side of the upper cell in contact with the cool side of the lower one; an experiment proved the two stacked cell cooling effect is much better than the single-stage. Similarly a three cell stack produces an even greater temperature differential but requires a larger capacity power supply support.

    Board V1.2 A4988 Big Easy Driver 2A Phase 3D Printer Stepper Motor Driver Board

















    Description: Replacement:ROB-11876. We’ve fixed a few silk screen errors on the next rev of this board including an incorrect current adjustment arrow indicator, go check it out! This page is for reference only.
    The Big Easy Driver, designed by Brian Schmalz, is a stepper motor driver board for bi-polar stepper motors up to 2A/phase. It is based on the Allegro A4988 stepper driver chip. It’s the next version of the popular Easy Driver board.
    Each BigEasyDriver can drive up to about 2A per phase of a bi-polar stepper motor. It is a chopper microstepping driver which defaults to 16 step microstepping mode. It can take a maximum motor drive voltage of around 35V, and includes on-board 5V/3.3V regulation, so only one supply is necessary. Although this board should be able to run most systems without active cooling, a heatsink is recommended for loads approaching 2A/phase. You can find the recommended heatsink in the related items below.
    Note: The arrow indicators on the current adjustment potentiometer is backwards. Keep this in mind if you’re adjusting the current limits.
    Note: This product is a collaboration with Brian Schmalz. A portion of each sales goes back to them for product support and continued development.
    Features:
    • Bi-polar Microstepping Driver
    • 2A/Phase Max
    • Max Motor Drive Voltage: 35V
    • On-board 5V/3.3V Regulation
