WANPTEK Variable DC Power Supply 30V 10A Bench Power Supply with 4-Digits LED Display Adjustable Switching Power Supply with Encoder Adjustment Knob Output Enable/Disable Button This lab power supply can display voltage, current, power and other parameters at the same time. And you can observe its constant voltage (CV) cross-current (CC) as well as short-circuit conservation (OCP) and output on/off (OutPut) indicator changes from the screen to know its working status! Features: 【Precise 4-digit LED Display】The variable power supply with a high-definition 4-digit display, which can display three values of voltage, current and power at the same time. The data is accurate to 0.01V and 0.001A. The bright white digital display helps you to operate as usual in the dark, and you can adjust the brightness of the screen as needed. 【Output Enable/Disable Button】In the process of using the bench power supply, Output button can prevent us from forgetting to turn off the output and causing damage to the load. Just press this button to turn on or turn off the output of the power supply. This makes it more convenient for you e the power supply. 【Overcurrent conservation】When the OCP function is turned on, if the load equipment is short-circuited during operation, the adjustable power supply will automatically stop output and send a buzzer to alert the user. Protect the adjustable power supply and load from damage. 【High-precision encoder knob】The DC power supply has a precise encoder knob. You can press the knob to toggle each digit, then turn the knob in the 0-9 range to customize each digit. Set the voltage or current you want more accurately. The option to set the voltage or current can be toggled with the (V/A) button. 【Application Field】Production line testing, repair of mobile phones/ computers/ electrical appliances, product aging and electroplating, battery charging, laboratory, scientific research, teaching, etc. Specifications: Plug: EU / US / UK / AU (Optional) Model: TPS305 / TPS3010 / TPS605 / TPS1203 / TPS1602 (Optional) Output Power: 150W / 300W / 300W / 360W / 320W Output Voltage: 0~30V / 0~30V / 0~60V / 0~120V / 0~160V Output Current: 0~5A / 0~10A / 0~5A / 0~3A / 0~2A Color: Black Material: ABS Input Power: AC 230V/115V ±10%; 50Hz/60Hz Operating Temperature: 0℃~ 40℃; Relative Humidity: <80%RH Storage Temperature: -10℃~70℃; Relative Humidity: <70%RH Mode: Constant Voltage (CV), Constant Current (CC) Voltage Stability: 0.1%±3mV Load Stability: 0.2%±3mV Ripple Voltage: ≤0.5%Vp-p Current Stability: 0.1%±3mA Load Stability: 0.2%±3mA Ripple Current: ≤0.5%Vp-p Recovery Time: ≤500μS Temperature Coefficient: ≤100ppm/°C Display Accuracy: 0.5%±3 words Display Resolution: Voltage 0.01V, Current 0.001A Item Size: 210 * 145 * 80mm / 8.27 * 5.71 * 3.15in Item Weight: 1200g / 2.65lb Package Weight: 1600g / 3.53lb Package Size: 30 * 19.5 * 13.5cm / 11.81 * 7.68 * 5.31in Package List: 1 * DC Power Supply 1 * Power Cord 1 * Test Line 1 * User Manual (English)
