ProductDescription:
Advantages:
All use of imported SMD aluminum electrolytic capacitors, high-power high-Q inductors. Additionally, each a plate have been strictly technical tests, all testing has been completed using a separate anti-static protection bags package. Specially designed two screw holes. Four input and output pads are provided with a pin fixing hole spacing 100mil are integer multiples, convenient volume applications in the product;
Note:
working long hours is recommended for use in less than 2.5A of current, and coupled with the heat sink (10W output above); Since the step-down module, in order to ensure stable output, keep a minimum 1.5V differential.
Voltage Regulator:
Access to power (3-40V), adjust the blue potentiometer knob (clockwise rotation generally boost, buck counterclockwise rotation) and with a multimeter to monitor the output voltage reaches the required voltage.
Wiring:
1. welding, welded directly to the power line input (output) port;
2. solder pins, or pins can be inserted through the lead insertion use in tunnel plate; soldered directly to the PCB after another or add pins.
