Description

Make sure this fits by entering your model number. Thermoelectric Cooler Module - Peltier Cooler Module - Peltier Module Water Cooler | 1. The red wire is connected to the power wire is connected to the anode, cathode, and without cooling conditions, the instantaneous power of the test, which touch the two end of the refrigerator, you will feel a fever, a little have a fever cold, heat, cold cold. But time can not exceed 5 seconds, otherwise the end temperature is too high, extremely easy to cause the device to burn out. 2. Under normal conditions, the lead with red is usually expressed as the positive pole: usually with black as the negative, this is the work of the thermoelectric cooler wiring method. When the current polarity is changed, the polarity of the current can be changed. Refrigeration work must adopt the switching power supply, power supply ripple coefficient should be less than 10%. 3. The number of the thermocouple and the limit voltage of the thermocouple identification method, the number of pairs of thermocouple P, N node. For example: cooler model for TEC1-12706, 127 for cooler thermocouple logarithm, 06 allowable current value: A, the threshold voltage is logarithmic thermocouple cooler * 0.12, for example: limit voltage V TECI-12706 = 127 x 0.12 = 15.4 (V). The normal operating voltage is 78% of the limit voltage, such as the working voltage of 15.4*0.78=12.01V is TEC 4. All kinds of cooler in use or in the test, the cooling and heating temperature of and cold exchange should be returned to the room temperature (usually more than 15 minutes). It is easy to cause damage of refrigerator.
