Item Description

Buck-Boost（WZ3605E）

Buck-Boost（ZK-4KX 35W）

1.2. CNC adjustment, accurate and fast, can boost and lower voltage, output voltage can be adjusted at will from 0.5-30v, limit current 0-4a can be adjusted at will;

1.3. Anti-reverse connection protection of input end, which will not burn out;

1.4. Anti-reverse irrigation at the output end, no additional anti-reverse irrigation diode is needed to charge the battery;

1.5. The module can be set to open/close by default;

1.6. 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 closed.

1.6. Output ripple is small and PI filter is available;

1.8. Thicken radiator fins.

Buck-Boost（ZK-5KX 80W）

 
(Buck-Boost（ZK-SJ4 35W）
Introduction:
Wide voltage input 4.8-30V, wide voltage output 0.5-30V, both boost and buck, for example, you adjust the output voltage to 18V, then the input voltage will change between 5-30V, it will output 18V constant; Input 12V, adjust the potentiometer to set any output of 0.5-30V.
High power, high efficiency and better performance than the XL6009/LM2577 solution. Large external power high-voltage MOS, large package high current and high withstand voltage Schottky diode. Increase heat dissipation and copper.
The current can be set to limit the output current, constant current drive, battery charging and other occasions.
It comes with an output anti-backflow function, so you don't need to add an anti-backflow diode when charging the battery.
Product parameters:
Input voltage: 4.8-30V
Output voltage: 0.5-30V
Output current: to long-term stability in the 3A, to strengthen the heat can reach 4A
Output power: natural cooling 35W, strengthen the heat 60W
Conversion efficiency: 88% or so
Short circuit protection: Yes
Operating frequency: 180KHZ
Size: Length * Width * Height 68 * 37 * 22mm
Weight: 39g
Package Included:
1 × Buck-Boost（ZK-SJ4 35W）
