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 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|
|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|
|Input 24V Output 12V 5A efficiency 92%|
|Input 36V Output 24V 5A efficiency 95%|
|Input 48V Output 24V 5A efficiency 93%|
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
