KUAIQU | KUAIQU 30V 10A 300W Adjustable Lab DC Power Supply 12V/24V/60V/120V Voltage Regulator M1/M2/M3/M4 Switching Source For Repair

KUAIQU 30V 10A 300W Adjustable Lab DC Power Supply 12V/24V/60V/120V Voltage Regulator M1/M2/M3/M4 Switching Source For RepairLooking for a compact, high-precision adjustable DC power supply for electronic repair, DIY circuit making, battery activation and daily device emergency charging? The KUAIUQ SPPS series multi-spec power modules cover low to medium power demands, integrating precise parameter adjustment, data real-time display and anti-misoperation protection. It is a must-have tool for electronic enthusiasts, maintenance technicians and laboratory personnel.Description:1. LED screen, 4-digit display with power indicator.2. Single-knob encoder for precise digital signal adjustment.3. USB-A 5V 2A output port for charging mobile phones.4. Four memory function buttons ("M1/M2/M3/M4") for one-button adjustment of current and voltage settings.5. "LOCK" screen lock button to prevent accidental touches that could cause changes in output current and voltage and damage to appliances.6. "V/A" current/voltage switch button for switching between current and voltage values using the single-knob encoder.7. "On/Off" output switch button (some models use "OUTPUT") for safer current and voltage output.Specification1️⃣ 4-digit High-definition LED Dual Data DisplayEquipped with industrial-grade 4-bit digital LED screen, supporting synchronous real-time display of voltage, current and output power. Unlike ordinary 3-digit display modules with low precision, this screen can capture tiny parameter changes during power output. You can intuitively check the actual output power without extra multimeter testing, which greatly improves the efficiency of circuit debugging and fault judgment. The screen has anti-glare coating, clear display under strong indoor light, no ghosting.2️⃣Single Encoder Knob for Ultra-precise Digital RegulationAbandon traditional sliding rheostat with large adjustment error and drift. Adopt imported single rotary encoder for full digital signal regulation. The knob features damping rotation design, with fine step adjustment. It supports millivolt-level voltage and milliamp-level current fine-tuning, no parameter drift after long-time operation. Perfect for high-precision scenarios such as chip power-on test, micro motor speed regulation and small sensor power supply.3️⃣ Built-in USB-A 5V 2A Independent Output PortIndependent isolated USB-A interface, stable 5V 2A constant output, no mutual interference with DC regulated output. It can directly charge mobile phones, Bluetooth headsets, smart watches and other portable digital devices without additional power adapters. Ideal for outdoor maintenance and desktop multi-device power supply scenarios, realizing dual power supply for industrial circuit and consumer electronics at the same time.4️⃣4 Groups of M1-M4 Memory Quick Recall ButtonsPreset 4 independent memory channels M1/M2/M3/M4. Users can store customized voltage and current parameters for commonly used equipment in advance, such as 3.7V lithium battery charging parameters, 12V fan operating parameters and 5V circuit test parameters. When switching test tasks, just press one corresponding button to restore all parameters in 0.1s, no repeated manual adjustment. It solves the tedious repeated setting problem for frequent multi-equipment maintenance work.5️⃣LOCK Screen Lock Anti-misoperation ProtectionSpecial LOCK physical lock button. After setting the optimal voltage and current parameters, press LOCK to lock the full screen and all adjustment keys. The encoder knob, V/A switch and output button will be disabled synchronously. It effectively avoids parameter offset caused by accidental touch during moving the module, wiring collision or crowded desktop operation. Prevent overvoltage and overcurrent damage to precision chips, circuit boards and expensive electronic test samples.6️⃣V/A One-click Voltage & Current SwitchingDedicated V/A toggle button to switch adjustment targets freely. When switched to V mode, the encoder only changes the output voltage; when switched to A mode, the encoder only adjusts the output current. The separated adjustment logic avoids misadjusting two parameters at the same time. The switching response is instantaneous with no delay, meeting fast switching debugging demands for constant voltage and constant current modes.7️⃣On/Off Independent Output Control SwitchIndependent physical On/Off output cutoff button, separate from parameter setting area. Users can keep all preset parameters unchanged and only turn on/off power output. It replaces frequent power plugging operations, avoiding instantaneous surge current generated by plugging and unplugging power supply. Effectively protect vulnerable electronic components such as capacitors and diodes from surge breakdown, improving overall operation safety.About Shipment:We will ship your package within 1-2 working days.
