Brand: WSDMAVIS

Model: WS031

Specifications:
Input voltage: 5.0-30V
Output voltage: 0.5-30V
Output power: natural heat dissipation 35W; strengthen heat dissipation 50W
Voltage display resolution: 0.01V
Current display resolution: 0.001A
Conversion efficiency: about 88%
Soft start: yes (it may fail when the module is power-on with high-power load)
Operating frequency: 180KHZ
Hole spacing For embedded installation: 75 x 39mm

Note:
After the product triggers protection mechanism, output will automatically turn off, and LCD screen will display protection code. Press any button to exit the protection interface.
To ensure the accuracy of calibration, only when the voltage is over 12V can voltage be calibrated. And only when the current is over 1A can current be calibrated.
The input terminal IN negative of the module must not be short-circuited with the output terminal OUT negative, otherwise the constant current function will fail.
Please ensure that the power of your power supply is greater than the power required by the output load.
When users need the module to output at full load, input voltage needs to be larger than 8V. When input voltage is 5V, output power is about 15W. The maximum current of module is 4A, which is limited by the maximum output power. For example, if the output is 17V, current should not be greater than 2A.
When this module is used over 3A, 35W, please strengthen heat dissipation devices.
The module has input under-voltage protection function. The default value is about 4.8V (can be set). If it is lower than this value, output will be automatically disconnected (Attention: The voltage at the port of module is lower than the under-voltage protection threshold. When input current is relatively large, please not ignore the divided voltage on input wire).

Package Includes: 1pcs


• LCD displays input/output voltage, output current/output power/output capacity/output time.The module can be set to ON/OFF by default.
• CNC adjustment enables accurate and fast adjusting. It can boost and lower voltage, with adjustable output voltage 0.5-30V, and adjustable current limit 0-4A(can work stably at 3A for a long time, and can reach 4A under enhanced heat dissipation).
• Anti-reverse connection protection of input end, so that it will not burn out when there is reverse connection.Anti-backflow protection at the output end. No need to add anti-backflow diode when charging. Multiple software protection mechanisms are available, and the protection threshold is adjustable.When the working parameters of the module exceed the protection threshold, the output will be automatically turned off.
• Input under-voltage protection (4.8-30V adjustable, default 4.8V)
• Output over-voltage protection (0.5-31V adjustable, default 31V)
• Output over-current protection (0-4.1A adjustable, default 4.1A)
• Over-power protection (0-50W adjustable, default 50W)
• Over-temperature protection (80-110℃ adjustable, default 110℃)
• Timeout protection (0-100h adjustable, OFF by default)
• Over-capacity protection (0-60Ah adjustable, OFF by default).
• Output ripple is small andπfilter is available.Thick heat sink.
