Adjustable Output Voltage \u0026 Current: output voltage and output current can be continuously adjusted between 0 and nominal value with fine regulating and coarse regulating.4. Clearly Display \u0026 Functional: LED 4 digits display of voltage, current and power, high precision and features of voltage stabilization, current limiting, and simple operation.5. Wide Application: can be used in mobile phone maintenance, computer maintenance, electrical maintenance, school laboratories scientific research and production line use and all other need DC regulated power supply.6. Supporting Fast Charging Protocols Include: compatible with qualcomm QC2.0, QC3.0, iOS, Huawei FCP, SCP Samsung AFC and other fast charging protocolsSpecification:The DPS series product is a high-precision switch type DC regulated power supply with three windows and four positions display, which can simultaneously display voltage, current, and power. The product is widely used for mobile phone repair, computer repair, school and production line use, and its output voltage and output current can be continuously adjustable using an encoder. The stability and ripple coefficient of the power supply are very good, and the machine has a perfect OCP short-circuit conservation circuit. Its small size, beautiful design, convenient operation, and ability to work at full load for long periods of time are deeply loved by users.Specifications:Material: Aluminium alloyModel: DPS3010UOutput Voltage: 030VOutput Current: 010AOutput Power: 300WAuxiliary Output: USB quick charging 18W, supports multiple quick charging protocolsInput Voltage: AC230V 10%, 50Hz; AC115V 10%, 60HzWorking Temperature: 0~40; Humidity: <80%RHStorage Temperature: -10~70; Humidity: <70%RHCV:Voltage Stability: 0.1% 3mVLoad Stability: 0.1% 3mVRipple Noise: 20mVrms (effective value)CC:Current Stability: 0.1% 3mALoad Stability: 0.2% 3mARipple Noise: 5mArms (effective value)conservation Mode: Current limiting conservation/short circuit alarm stop output and self-recoveryDisplay: Four-digit digital tube, three-window display: voltage, current, powerDisplay Accuracy: 0.5% 3 digitsDisplay Resolution: voltage 00.01V; current 0.001AFuse: 3AItem Size: 246 * 90 * 152mm / 9.68 * 3.54 * 5.98inItem Weight: 1571g / 55.42ozPackage Weight: 1737g / 61.29ozPackage Size: 30 * 20 * 14cm / 11.81 * 7.87 * 5.51in.Package List:1 * DC Power Supply1 * Power Cord1 * Alligator Clip Line1 * User Manual (English)
