Check the listing for details. 0~30V 6A Adjustable Bench DC Power Supply Lab Variable Regulated Power Switching. Condition: New. Listed at 52.99 USD. 30V 10A Lab Adjustable Bench DC Power Supply Variable Encoder Adjustment Knob product descriptionWanptek's new NPS-W series products include 4 models, namely NPS306W, NPS3010W, NPS605W, and NPS1203W. The body colors are available in black and off-white. This model is a miniature switching DC power supply. The product improves the shortcomings of the traditional linear power supply, such as large volume, heavy weight, and poor efficiency. The output voltage and current can be controlled and adjusted by variable resistors respectively, so it provides more convenience and accuracy in the adjustment of voltage and current. The panel also provides high-precision three-window digital tube display of voltage, current and power, so that users can intuitively see the current use status and various parameters of the machine Product FeaturesTwo body colors, user's personal choice.Small size, light weight and high power density.Constant pressure and constant current switch automatically.Three LED display of voltage, current and power, high precisionTemperature controlled fan cooling, low noise, long life Application field1. Production line test.2. Mobile phone, computer, electrical appliance maintenance.3. Product aging, electroplating.4. Charge the battery.5. Laboratory, scientific research teaching.6. All other occasions requiring DC power supply.
