Product Description
DC Power Supply Variable, 30V/6A Adjustable Switching Regulated DC Bench Linear Power Supply with 4-Digits LED Power Display 5V/2A USB Output, Coarse and Fine Adjustments with Alligator Leads
Model:
NPS306W
, and the body color is black . This model is a mini-type switching DC power supply. The product improves the shortcomings of the traditional linear power supply of large size, heavy weight, and poor efficiency. The output voltage and current can be controlled and adjusted by variable resistors, so it provides more convenience and accuracy in the adjustment of voltage and current. The panel also provides high-precision display of voltage, current and power in three windows, so that users can intuitively see the current state of use and various parameters of the machine.
Product Features:
*High Precision with 4-Digit and Power Display: 30V10A DC benchtop power supply is a professional power supply regulation device that has a high resolution of 0.01V and 0.01A. You can easily tune it within 0-30V and 0-6A. The backlit 4-digit LED display provides a more accurate readout for the voltage and current value, visible easily even in the low-light conditions.Constant Voltage (C.V.) & Current (C.C.) Mode Automatic
*
Conversion: Easy to dial in the desired voltage and current with the coarse and fine adjustment knob. The constant voltage/current mode can automatically switch with load changes. The conversion of constant voltage and constant current is indicated by the LED display on the front panel.
*Compact and Various Application: This DC power supply is less than 3 lb and measures only 9.5 x 3.4 x 6.1 inches, applies for laboratory, school, repair, electrolyzation, electroplate, brush plating, lamp test, aging testing, battery charge, home DIY and other requirements. 5V/2A USB Interface could charge your cellphone and provide power for the device which you want to repair, no worry about running out of power.
*Reliable and Safety: Many safety measures are adopt in Kungber DC bench power supply- Grounding wire, Leakage protection, Thermal protection, Voltage overload, Power overload and Short-circuit protection. Kungber power supply use premium electronic components, provide reliable working status and prolong the life of product effectively. When the working temperature is more than 122℉/50℃,the intelligent thermal protection will active the cooling fan to lower the temperature according to the load

Constant Voltage / Constant Current Crossover Characteristic
The working characteristic of this series is called a constant voltage/ constant current automatic crossover type. Thispermits continuous transition from constant current to constant voltage modes in response to the load change. Theintersection of constant voltage and constant current modes is called the crossover point.
For example, if the load is such that the power supply is operating in the constant voltage mode, a regulated outputvoltage is provided. The output voltage remains constant as the load increases, up until the point where the presetcurrent limit is reached. At that point, the output current becomes constant and the output voltage drop isproportioned to further increases in load. The crossover point is indicated by the front panel LED indicators. Thecrossover point is reached when the CV indicator goes out and the CC indicator is on.
