Product Description

DC-DC Adjustable power supply module
 
Module Properties:Non-isolated high-efficiency regulator, constant voltage module
Scope:High-power solar &vehicle power supply, wide input voltage system.
DIY 30V 5A adjustable power supply,etc.
Output Power:  1-50W    
Output Type: Single, adjustable
Input Voltage:8-56V  input DC voltage (58V) limit (no input AC)
Output Voltage:2-45V precision adjustable (step-down module,input 3V higher than output)
Output Current:Rated 5A
Dimension:LWH 61*55*30mm
Origin:Japan
Efficiency:up to 95%
Over-current :(Ultra-6A over current ), with over-current self-recovery function
Operating temperature:Industrial grade (-40°C to +85 °C)
(When temperature >40°C, to lower power use or need heat dissipation)
Full load temperature rise:38 °C
No-load current:Typical 15mA (12V turn to 5V)
Load Regulation:± 1%
Voltage regulation:± 0.5%
Dynamic response speed:5% 200uS
Indicator:Output power indicator
Output short circuit :Short circuit after discharge automatically resume output
Input Reverse Polarity:No diode in series with the input. Make sure the wiring is correct then test
Wiring:Wiring terminals
Conversion efficiency
for reference
Input 24V Output 12V 5A  efficiency 92%
Input 36V Output 24V 5A  efficiency 95%
Input 48V Output 24V 5A  efficiency 93%

  Note:
  1.High-current and high-voltage inputs need heat dissipation, and should have sufficient margin!
  2.DO NOT reverse polarity, make sure the positive &negative input and output wire is CORRECTLY connected and then power-on test. For the output current is relatively large, input and output wire must be short and thick to reduce loss.
  3. It is a step-down module,input voltage should be 3V higher than output.
     e.g  Output 5V, input voltage between 8V-55V
         Output 12V, input voltage between 15V-55V
         Output 24V, input voltage between 28V-55V
  4. Input 56V output voltage can be 2-48V precisely adjustable
