Product description NTC thermistors are temperature-sensitive resistor elements using semiconductor ceramics with negative temperature coefficients (NTC). That means that the resistance decreases exponentially with rising temperature. The steeper the RT curve, the greater the change in resistance within a specified temperature range. With this property, they are often used as temperature sensors and also used as temperature protection devices for purposes such as temperature measurement and temperature compensation. Specifications Resistance @+25℃ (Ohms）: 100K Beta Value: 4250 Tolerance on Beta Value: 1% Operating Temperature: -30℃~125℃ (-22℉ to 257℉) Length: 100mm Material: PVC Temperature accuracy ±0.2ºC from 0ºC to +70ºC Feature Fast time response and High Accuracy: The small size NTC thermistor comes with high sensitivity, fast response, strong non-interference ability, and high accuracy Constant Temperature Control:Widely used in constant temperature control, industrial systems, consumer products, thermometers, all thermal systems. -30℃ TO 125℃ Range: PVC material is lightweight, thermal insulation, heat preservation and flame retardant. The temperature measuring range is -30℃ to 125℃ (-22℉ to 257℉) Application NTC thermistor is used in battery protection, monitoring the temperature of battery packs during charging, lithium battery equipment, and overheating protection of portable power.

Specifications-- 1. Input voltage: 9V-90V The minimum voltage difference between the input voltage and the output voltage is 4V  (when the output is 5V, the input is DC9V-90V, and when the output is 12V, the input voltage is DC16V-90V. 2. Output voltage: 12V/5V 3. Maximum output current: 3A (that is, the constant current value is 3A, when the customized voltage is higher than 12V, the output current is less than 3A, the power is not recommended to exceed 30W, 12V and 5V can reach 3A.) 4. Typical operating frequency: 140KHz 5. High efficiency: up to 95% (the smaller the pressure difference, the higher the efficiency) 6. Working temperature: industrial grade (-40℃ to +85℃) 7. Module volume: 42*30*17mm   Product Advantages-- Frequency reduction at light load to improve light load efficiency. Small standby current. Built-in over-temperature, over-current, output short-circuit protection. Built-in soft start. Constant voltage and constant current output.   Instructions: First connect the connection line between the module and the power supply, and then power on. (If the input terminal is connected with electricity, it is prone to sparking, especially when the input power supply voltage is high, the pad of the module may even be burnt). After selecting a suitable power supply, use a multimeter or voltmeter to measure whether the output voltage of the module is consistent with the voltage required by the device. Connect electrical equipment or (load) to the output of the module. Package List: 1x DC-DC STEP-DOWN POWER SUPPLY MODULE

Maxkgo 150V 3A high power step-down module   Specifications: Maximum 150V input 3A current output 1-9mA quiescent current Up to 95% conversion efficiency -40°C to +85°C Dynamic frequency conversion and low ripple Output short circuit protection Built-in over-temperature protection The main purpose: Car charging equipment power supply Constant voltage power supply Solar power conversion Electric vehicle converter Features: Small size, high power Dynamic frequency conversion and low ripple Strong heat dissipation aluminum substrate—— The life of the power supply is related to the operating temperature. The lower the temperature, the longer the life. The module uses an aluminum base plate, which has far better heat dissipation performance than ordinary composite panels and has a longer service life. If the module fits the equipment shell or other metal materials to assist in heat dissipation, the lifespan will be longer. 3000V voltage resistance, no need to worry about leakage of aluminum shell. Dimensions: When the board is not plugged in, the height is 17MM, and the size of the 4 screw holes is 3MM. During installation, the board can be directly attached to a fixed object according to the actual situation to enhance heat dissipation. Vout=(R3/R2+1)x1.2 Module interface: IN+: DC input positive pole 10V-130/150V (needs to be more than 5V higher than the output) IN-: DC input negative pole, connected to the negative pole of the output OUT+: DC output positive pole. OUT-: DC output negative pole, connected to the input negative pole. Attention： 1. The input of the product should be greater than the output voltage, and it is best to maintain a voltage difference of more than 5V. The input cannot be connected reversely or connected to the anti-burn board. During installation, the board can be directly attached to a fixed object according to the actual situation to enhance heat dissipation. 2. Connect the input first, not the output device. First connect the connection cable between the module and the power supply, and then turn on the power. Otherwise, high voltage may easily cause sparking, which may cause damage to the circuit. After selecting a suitable power supply, use a multimeter or voltmeter to measure whether the output voltage of the module is consistent with the voltage required by the equipment, and then connect the electrical equipment. The wiring should not be too thin to ensure that the wire can withstand the corresponding current. 3. Protect inductive loads to prevent excessive reverse electromotive force beyond the chip's endurance range. If you need to work for a long time, you should purchase a power module with higher power. The actual power used by the load device should account for 30%-75% of the rated power of the module. Full load or overload use has a great impact on module stability, temperature, service life, etc. The greater the power used by the module and the closer the current is to the maximum current, the greater the heat will be. Pay attention to heat dissipation when using it. 4. This module is a non-isolated power supply. If the equipment is expensive and is used in high voltage and complex environments, it is recommended to use an isolated power supply (with an isolation transformer).
