Descripción

Product description YITRANIC 30V/10A adjustable DC power supply – engineered for tight spaces and demanding precision. Compact and space‑saving, yet strong enough to deliver 300W of clean, continuous power with 0.01V/0.001A precision. Whether on a crowded repair bench, a repeat‑task production line, or a training lab with novice users, it streamlines your daily work: preset memory function eliminates repetitive settings, dual start‑up modes (auto‑start or manual‑start) give you flexible control, and five layers of protection combined with a lockable keypad keep both the unit and your devices safe from accidental missteps. Built for electronics engineers, lab instructors, and mobile service technicians who refuse to compromise – this is the dependable starter that brings bench‑grade performance to any workspace, no matter how tight. Who is this bench power supply for? Repair techs – Troubleshoot laptop motherboards, ECUs, drone flight controllers, audio amps. Trace shorts, verify voltage rails on PCBs. Makers – Power Arduino/ESP32, test LED arrays, tune motors, charge Li‑ion packs – no permanent bench space required.Students & educators – Run I‑V curves for diodes/transistors, verify Ohm’s law, power lab circuits from intro to advanced. Auto/battery specialists – Simulate 12V alternators or 24V truck systems, cycle lead‑acid/LiFePO₄ batteries, stress‑test motors, pumps, solenoids. Product Highlights Dual switches for added safety USB fast charging port (18W) Long press to save preset values Long press to lock/unlock Voltage knob – long press for two functions Auto‑start: Output turns on immediately when the device is powered up – no need to press the output switch. For safety, we recommend disabling this mode. To disable auto‑start: 1. Press the output switch to turn off the output (output switch become red). 2. Long‑press the voltage adjustment knob.

Características

• [PRECISE CONTROL] This laboratory Bench power supply features a wide-range input of 100-240V, making it usable worldwide. The output is continuously adjustable from 0-30V / 0-10A. The 4-digit LED display offers a resolution of 0.01V / 0.001A. Ideal for sensors, development boards, and demanding electronics projects – delivers clean, stable power for professionals and enthusiasts
• [COMPACT DESIGN, FULL 300W POWER] Measuring only 220×102×80mm (1kg) yet delivering a full 300W output power. Thanks to the ultra-compact housing, this DC power supply is ideal for crowded workbenches and mobile use – finally independent from heavy, old laboratory power supplies
• [DUAL-SWITCH + MEMORY FUNCTION] Safety & efficiency laboratory power supply. Unique dual-switch logic: first set the parameters, then activate the output – reliably prevents damage to components caused by hot-plugging. The one-touch memory function automatically remembers the last settings and recalls them the next time the unit is powered on. Ideal for repetitive testing – no need to re-adjust, significantly higher work efficiency
• [QC18W USB Port] The QC3.0 fast charging port (18W) charges smartphones or tablets while the variable power supply is in operation. Saves wall outlets and chargers – keeps your workspace tidy without extra cables.
• [5-FOLD PROTECTION + KEY LOCK] Protection against overvoltage, overcurrent, overload, reverse polarity, and overtemperature. In case of danger, the output is interrupted immediately. The key lock prevents accidental changes – ideal for training, repair, and 24-hour continuous tests
• [Auto CC/CV Mode Switching] Automatically transitions between Constant Voltage (CV) and Constant Current (CC) modes based on the connected load – ensuring optimal power delivery without manual intervention
