5A 75W DC-DC Step down Power Module Adjustable With LED Voltmeter FREE Pillars 1. 5A -power high-efficiency step-down low ripple 2. Power indicator ! 3. With voltage meter, voltmeter can be self-calibration, will never exist without accurate voltmeter problem 4. FREE Pillars Module performance and features: With power indicator With voltmeter voltage meter can display and self-calibration. Uses a more advanced microprocessor voltage voltmeter error 0.05V, range 0 ~ 40V. (Note: To ensure accuracy voltmeter , please ensure that the input voltage is 4.5V or more) touch of a button to switch the input or output voltage measurements and has a light display which is being measured voltages , and save the settings , even power off and then on. voltmeter can be turned off when not needed Tap the left button can be easily achieved . With terminals, no soldering iron can also be easy to use , and retention wire connection point . Input Voltage 4.0 ~ 38V. (Input voltage must be higher than the output voltage of 1.5v or more) Adjustable output voltage range of 1.25V ~ 36V continuously adjustable. (1.5V input voltage must be higher than the output voltage) Output current up to 5A, recommended for use in the 4.5A. output power 75W. high conversion efficiency, up to 96% (efficiency and input and output voltage, current , pressure related) Load Regulation S (I)0.8%, voltage regulation rate S (u)0.8% With overheat protection and short circuit protection Size 6.6 x 3.9 x 1.8CM Package included: 1x 5A 75W DC-DC Step down Power Module 1x Set of Pillars and Screws
