1 Pack LM2596S DC DC 3 40V Adjustable Step Down Power Supply Module Voltage Regulator 3A

Note:Working long hours recommended within 2.5 A current use, at the same time combined with heat sink (more than 10 w output); Because it is step-down module, in order to guarantee the stability of the output, please keep the minimum 1.5 V differential pressure. Voltage regulation Plugged into a power supply (3-40 v), blue potentiometer adjustment knob (generally booster clockwise, counterclockwise step-down) using multimeter to monitor the output voltage to the voltage. Connection mode 1. The welding, welding the input (output) port directly to the power cord; 2. The welding pin, can lead the insert pin or inserted in the hole hole plate use;Or add pins after welding on the PCB directly. Application example 1. Automotive regulated power supply, this module input can only need to be connected to the car power supply point a cigarette holder, can adjust potentiometer, 1.25 30 v output voltage can be arbitrary adjustment, for your mobile phone, MP3, MP4, PSP charging many equipment such as power supply, very easy and convenient. 2. To the electronic equipment power supply, when a device needs 3-35 v power supply and corresponding voltage power in his hand, with this module can be adjusted the voltage to the voltage required, solve the problems. 3. The system operating voltage test, when doing project can use this module debugging the various working voltage range, voltage test system is very easy and convenient.
