SUNON High Quality Electronic Cooling Fan. 12VDC 40x40x20mm 6.5CFM 65mA 6000RPM Noise <25.5dB
Red & Black wires (not shown)
Dry soldering-iron tip cleaner that maintains the tip temperature of your soldering iron.
Leaves a fine amount of solder on the tip, preventing temperature loss and corrosion, compared to a wet sponge.
Complete with alloy dish
Solderless Female to Female Jumper Leads in a set of 40
This set of coloured female to female jumper leads can be used together or peeled apart into smaller sets or single leads. They are great for prototyping with boards like Arduinos and Raspberry Pi.
With 10 different colours and 4 of each colour, it's easy to keep track for quick fault finding.
Colours: Red, Orange, Yellow, Green, Blue, Grey, Purple, Brown, Black and White
9A DC-DC Step Down Voltage Regulator (Buck Converter)
This step down voltage regulator uses high frequency switching to make a very efficient DC-DC converter. It can take an input of 5V to 40V and lower it to between 1.2V and 35V at up to 9A(output). The voltage is set with one potentiometer and the constant current can be set with the other from 200mA to 9A.
note: If using this converter at its limits, you will need to fan cool the converter.
Voltage in : 5V - 40VDC
Voltage out : 1.2V- 35VDC
Constant Current Range : 200mA - 9A
Maximum Output Current : 9A
Dimensions : 65mm x 48mm
4S Balanced BMS (Battery Management System) for use with 4 x 3.7v Lithium batteries
This BMS is designed to charge and manage the use of 4 lithium batteries. It will manage the balanced charging when used with an apropriate constant current power supply for the batteries. It will also protect the batteries from both over voltage and under voltage. It also features over current and short circuit protection.
This BMS will balance charge 4 lithium batteries like 18650 or 26650 or can charge multiple sets of 4 in paralel for higher capacity/current uses. It will also balance charge 4S LiPo (Lithium Polymer) battery packs.
Voltage in : 16.8V - 18.1VDC
Over Voltage Protection : 4.2VDC per cell
Under Voltage Protection : 2.5VDC per cell
Maximum Charging Current : 20A
Maximum Discharging Current : 40A
Over Current Protection : 80A
Dimensions : 60mm x 45mm
5A DC-DC Step Down Voltage Regulator (Buck Converter) Constant Voltage, Constant Current
This step down voltage regulator uses high frequency switching to make a very efficient DC-DC converter. It can take an input of 6V to 38V and lower it to between 1.2V and 36V at up to 5A (output). The voltage is set with one potentiometer and the constant current can be set with the other from 0.1A to 5A.
Voltage in : 6V - 38VDC
Voltage out : 1.2V- 36VDC
Constant Current Range : 100mA - 5A
Maximum Output Current : 5A
Dimensions : 52mm x 26mm
Dual Display Panel Meter, 0-100VDC and 0-10ADC
This handy compact panel meter will display the voltage and current clearly. It is ideal for a bench power supply or any project that requires accurate voltage and or current measurement. The meter can either be powered from the supply it is measuring if it is between 4.5-30VDC or from an independant power source.
Voltage Measurment : 0 - 100VDC
Current Measurment : 0 - 10ADC
Working Voltage : 4.5 - 30VDC
Dimensions : (W)48mm x (H)29mm x (D)22mm
Red (Thick) - Voltage in for Current Measurment
Black (Thick) - Voltage out for Current Measurment
Red (Thin) - Supply Positive 4.5-30VDC (connect to voltage to be measured if not using a seperate supply)
Black (Thin) - Supply Ground (Do not connect if not using a seperate supply)
Yellow (Thin) - Voltage to be Measured 0-100VDC
