  • –LCD can display input/output voltage, output current/output power/output capacity/output time.
  • –Numerical control adjustment, accurate and fast, can be boosted and bucked, the output voltage can be adjusted arbitrarily from 0.5-30v, and the current limit can be adjusted arbitrarily from 0-4a.
  • –The input end is protected against reverse connection and will not burn out.
  • –The module can be set to open/close by default.
  • –Small output ripple, optional PI filter.



1. The output terminal is anti-backflow, no additional anti-backflow diode is needed to charge the battery.

3. Thicken the heat sink.

Name: Buck-Boost Power Supply Module
Input voltage: 5-30vdc (if the input voltage is lower than 5.5V, it will affect the voltage measurement accuracy, and the line loss voltage drop needs to be considered when using, and the lower the input voltage is, the smaller the output power is)
Output voltage: 0.5-30v
Output current: conventional 3a, enhanced heat dissipation can reach 4a
Output power: conventional 35W, enhanced heat dissipation can reach 50W
Voltage display resolution: 0.01V
Current display resolution: 0.001a
Conversion efficiency: about 88%
Protection mechanism: input anti reverse connection; Output anti backflow; Input undervoltage protection (4.8-30v adjustable, 4.8V by default); Output overvoltage protection (0.5-31v adjustable, 31v by default); Output overcurrent protection (0 – 4.1a adjustable, 4.1a by default); Output over-power protection (0 – 50W adjustable, 50W by default); Over temperature protection (80-110 ° C adjustable, 110 ° C by default); Timeout protection (0 – 100h adjustable, closed by default); Over capacity protection (0 – 60ah adjustable, off by default)
Working frequency: 180khz
Packing list:
1 x Buck-Boost Power Supply Module
