You can remove the protective film before use.Product Features🔥Precise 4-digit LED Display, Auto Power Calculation: The KUAIQU DC power supply variable is a professional switching power supply regulation device with a high resolution of 0.01V and 0.001A. The variable power supply features a big bright 4-digit LED display that shows the adjustable power supply output values of Voltage (V) / Current (A) / Power (W) in real-time. The high-definition backlit 4-digit LED display provides an accurate and clear readout for the voltage, current and power values even if you are in low-light condition.🔥Output Switch Control: Sometimes we need to switch between different voltage or current outputs in experiments or work, but we often forget to turn off the output and causing damage to the load. The adjustable DC power supply OUTPUT key is designed to solve this problem, just with a single press of the added OUTPUT key, you can easily turn the output on or off. The required voltage and current can be adjusted without actual output power, which makes this benchtop DC power supply more secure and more energy saving. Also, you don't need to remove the load or turn off the power each time, making the variable DC power supply more convenient and efficient to use.🔥Encoder precision adjustmentIn DC power supplies, an encoder knob is a common human-machine interaction component used to adjust output voltage, current, or other parameters. Compared to traditional potentiometers, encoder knobs have advantages such as digital control, high precision, and long lifespan.Function implementation of encoder knob(Parameter adjustment)Voltage/current setting: Rotate the knob to change the target value, with adjustable steps (such as coarse/fine adjustment mode).For example, the step size is ± 0.1V for fast rotation and ± 0.01V for slow rotation.Advantages of Encoder vs PotentiometerCharacteristic encoder knob, traditional potentiometerAdjustment method: digital signal (no physical wear), analog resistance (mechanical wear)High precision (accurate to mV/mA level) and low precision (affected by resistance linearity)Function extension supports interactive functions such as pressing and holding, and only rotation adjustmentLifespan: Millions of rotations, thousands to tens of thousands of rotations🔥Reliability and Safety: Safety is our priority, all lab power supplies are certified. The adjustable switching regulated power supply is built with premium electronic components and reliable circuit designs that include multiple protection functions, such as leakage, grounding terminal, over-voltage, over-current, over-power, over-load, over-temperature, short-circuit protection to ensure stable working performance and prolong the life of the adjustable DC power supply effectively.🔥5V 2A USB Port, Intelligent Cooling Fan: Complaining about mobile phones or repaired devices not being charged in time? The NICE-POWER adjustable DC power supply allows you to avoid this dilemma. The variable power supply has built-in 5V 2A USB charging interface which can quickly charge any USB devices anytime. The adjustable power supply features with intelligent temperature-controlled fan and heat sink for excellent heat dissipation when the working temperature of the switching power supply exceeds 122℉/50℃, greatly reduce working noise and improving the DC regulated power supplies working efficiency and lifespan🔥Compact Design, Lightweight and Portable: The DC voltage stabilized power supplies adopt stable vertical design with the shock-absorbing rubber feet on the bottom of bench supply, making it safer and more stable when using. The size of adjustable DC power supply is 8.43.35.5 inches and the lab power supply weighs only 2.6 lbs, which is very light and portable. You can carry your bench supply in and out of various workplaces🔥Various Applications: This benchtop power supply is suitable for battery charging ( LiFePO4, lead acid batteries, etc.), electronics repair, communication equipment maintenance, electrolysis, electroplating, brush plating, lamp test, aging test, burn-in test, production line test, DIY, labs, schools, laboratories scientific research and teaching etc. The KUAIQU DC power supply is a nice choice for beginners or professional electricians and DIY electronics hobbyist🔥Quality Assurance, Customer Service: Purchasing from KUAIQU, you will get DC power supply variable (all-metal body with ABS buttons)1, output power cord1, input power cord1, user manual1, efficient after-sales service, technical support. We will inspect all lab power supplies and accessories before shipment to ensure that the quality of the adjustable switching DC regulated bench power supply received by each customer is good. If you have any questions about our variable power supply, please let us know without hesitation. Please use the power supply under occupied condition. Please avoid violent impact or dropping of the power supply🔥Stable Output, C.V./C.C. Automatic Conversion: This variable DC power supply is a low noise, low ripple adjustable continuous output power supply that can work at full load for a long period of time. The bench power supply can be used as a constant-voltage (C.V.) power supply and constant-current (C.C.) power supply even when the load is changed. The constant voltage/current mode can automatically switch with load changes, you can check the working status indicator on the LED display🔥Front Power Switch, Precise Coarse & Fine Adjustment Knobs: Upgrade from the old-fashion switching power supply, the brand new version power switch is on the front of DC regulated power supplies, you do not need to turn to the back to turn on/off the adjustable switching regulated power supply, easy and convenient to use. The adjustable switching DC regulated bench power supply features with precise coarse and fine voltage/current adjustment knobs, you can set the desired voltage and current on NICE-POWER bench supply effortlessly🔥Warm Tips: Accuracy for NICE-POWER bench power supply: constant voltage state with voltage stability≤1%+30mV and load stability≤1%+30mV, constant current state with current stability≤1%+30mA and load stability≤1%+30mA, display accuracy: 1% +5digits. To measure the DC power supply accuracy correctly, please do not connect any load and ensure the multimeter is properly set to the DC voltage/current measurement range. Please kindly note that Ohm's Law is always be followed when using the DC power supply, and cables come with power losses causing slight differences in accuracyDC Power Supply Variable SpecificationInput Voltage 110V±10% 60Hz or 220V±10% 50HzWorking Temperature 0 ℃-40℃; Relative Humidity: ＜80%RHStorage Temperature -10 ℃-70℃; Relative Humidity: ＜70%RHConstant Voltage State Voltage stability≤0.1%+3mV Low Voltage:0.2~0.3%+3mV Load stability≤0.5%+3mV Ripple noise≤30mVrmsConstant Current State Current stability≤0.2%+3mA Load stability≤0.2%+3mV Ripple noise≤20mArmsDisplay Accuracy 0.5%+2digitsDisplay Resolution Voltage: 000.1V / Current: 0.001AProduct Dimension 3.3 x 8.4 x 5.5 InchesProduct Weight 2.6 lbFuse Standard 5A- Load Regulation- Voltage：≤ 0.3% + 10 mV- Current：≤ 0.1% + 2.5 mA- Line Regulation- Voltage：≤ 0.01% + 2.5 mV- Current：≤ 0.1% + 2.5 mA- Setting Resolution- Current：1 mA- Readback Resolution- Voltage：10 mV；<100V: 10mV，≥100V: 0.1V- Current：1 mA- Readback Accuracy- Current：≤0.01% + 10 mA- Voltage：≤0.05% + 10 mV；≤0.01% + 15 mV- Current：≤0.01% + 10 mA- Ripple (20Hz~20MH)- Voltage：≤ 100 mVp-p、≤ 200 mVp-p、≤ 300 mVp-p；≤ 15 mVrms、≤ 20 mVrms、≤ 30 mVrms- Current：≤ 15 mArms、≤ 20 mArms、≤ 30 mArms- Rise Time (No Load)- Time：≤200ms- Rise Time (Full Load)- Time：≤300ms- Fall Time (No Load)- Time：≤20S；≤30S- Fall Time (Full Load)- Time：≤300ms- Dynamic Response- Time：≤200ms- Efficiency：≥85%- Input Voltage/Current**：AC 220V or AC110V- Size/Net Weight：Size: about 228.515.5cm, weight: 1.2KG- Package Size/Weight：Single unit: 29.51321cm, weight: 1.65KG（8pcs/Carton）Black As BelowAbout ShipmentWe will ship your package within 1-2 working days.
