Output voltage: 1.5-32V continuously adjustable.
5A peak current, recommend to use within 4.5A.
High conversion efficiency, up to 96%(efficiency affected by input and output voltage, current and pressure difference).
Delicate transparent acrylic case, components can be well protected and looks stylish.
A great DIY kit for DC-DC step-down power supply module.

Note:
1. When the output exceeds 3A or 35W, please pay attention to heat dissipation; you can install a small fan on the input terminal.
2. The constant current is adjustable when output voltage>2V; current adjustment works under constant current state.
3. It's not under constant current mode until the load output current is larger than the setting current; otherwise, it would work under constant voltage state.
4. Before charge for USB devices, please make sure that the output voltage is adjusted to 5V; if higher than 5.5V, the screen would flash to remind you to adjust voltage.
