  AC-DC step down converter Description :


This power supply board imported from Japan, high efficiency Wide operating voltage buck regulator power supply module designed. Conversion efficiency up to 95% full spike traditional power module high energy consumption problems! More suitable for solar buck, vehicle power battery-powered systems and requirements of energy saving occasions. Has a wide input voltage, output short-circuit and over-current protection. 55V input voltage, the output can be 8-45V precise adjustable, 50V 1000UF low resistance high withstand voltage capacitor two Japanese imports. Output ripple voltage is low, strong load capacity!

dimension : LWH 61 * 55 * 30 mm


   Because the design professional! So the quality was better guaranteed!

Module parameters

Module Properties: non-isolated high-efficiency buck regulator, constant voltage module

Scope: high-power vehicle power supply, wide input voltage requirements of the occasion, DIY 30V 5A adjustable power supply, etc.

Input voltage :8-56V input DC voltage (58V) limit (no input AC)

Output voltage :2-45V precision adjustable (step-down module input than output high-3V)

Output Current: Rated 5A

Over-current protection:. (Ultra-6A overcurrent protection), with over-current protection self-recovery function

Please keep the input output 5V differential pressure the lowest dropout: 3V large current

Conversion efficiency: up to 95%

Operating temperature: Industrial grade (-40 ° C to +85 ° C) (ambient temperature exceeds 40 degrees, lower power use, or to enhance heat dissipation)

Full load temperature rise: 38 ° C

No-load current: Typical 15mA (12V turn 5V)

Load Regulation: ± 1%

Voltage regulation: ± 0.5%

Dynamic response speed: 5% 200uS

Indicator: Output power indicator.

Output short circuit protection: Short circuit after discharge automatically resume output

Input Reverse Polarity Protection: No diode in series with the input. Make sure the wiring is correct then test

Wiring: Wiring terminals

None of input and output reverse polarity protection, when in use must make sure that the positive and negative input and output power cord is properly connected and then power-on test. Because the output current is relatively large. Input and output leads must be as short and thick! To reduce the loss of the wire.
