DC Power Supply, 30V 10A Bench Power Supply with Encoder Adjustment, 5V/3.6A USB&Type-C Quick-Charge, Adjustable Power Supply with Output Enable/Disable Button, Short Circuit Alarm — Open-Box, 14% Off
Brand: NANKADF
Description
PRECISE ENCODER & AUTO CV/CC SWITCHING: NANKADF variable DC power supply features a precision encoder: press to cycle through digit positions, rotate 0–9 to fine-tune each one, delivering 0.01V / 0.001A resolution across the full 0–30V / 0–10A (300W) range. It automatically switches between Constant Voltage (CV) and Constant Current (CC) modes the moment your load crosses the limit—no manual mode changes needed when debugging circuits, charging batteries, or testing LED strips.
ONE-TOUCH OUTPUT & POWER-OFF MEMORY: The dedicated Output button lets you energize or cut power to your load instantly—essential when connecting probes or reworking circuits, so you never forget to kill output before touching a live board. This adjustable bench power supply recalls your last voltage/current values the next time you power on, picking up right where you left off.
DUAL 18W USB-A & USB-C FAST-CHARGING PORTS: Skip the separate wall charger cluttering your bench. Unlike basic lab power supplies with no USB or a single slow port, this DC power supply packs both USB-A and USB-C ports, each delivering up to 18W QC fast charge. Top off your phone, tablet, wireless earbuds, or power bank while you work—perfect for long repair sessions or all-day lab runs.
4-LAYER SAFETY PROTECTION: Built-in Over Voltage Protection (OVP), Over Current Protection (OCP), Over Temperature Protection (OTP), and short-circuit alert. On any short circuit, output cuts off automatically with a buzzer alarm. Protects your variable power supply and devices—motherboards, car ECUs, prototypes—from spikes, shorts, and overheating.
ADJUSTABLE BRIGHTNESS, SMART FAN & KNOB MUTE: LED display with adjustable brightness, readable in dim shops or glare-free in bright rooms. Smart fan stays quiet under light load and starts only at temperature threshold. Long-press the voltage knob to enter settings and toggle buzzer on/off. Ideal for electronics repair, school labs, prototyping, and automotive diagnostics.
