NICE-POWER DC Power Supply Variable, 0-30V 0-20A 600W High Power Bench Power Supply with Encoder Knob & Output Switch, Benchtop Adjustable Switching Regulated Power Supplies for Repair/Test(Black)

PLEASE NOTE. DC power supply input voltage AC 115V ±10% 60Hz. Before powering on, carefully inspect the product specifications on the body/package to avoid irreversible damage to the power supply. Due to the design of the power supply, the front panel is only suitable for output currents up to 5A. To avoid damaging the power supply or load and output more accurately, connect the high current connector on the back of the unit for output currents above 5A. The back panel can reach the maximum current of the purchased specification: for example, if you purchase 30V 30A, the current can reach 30A by connecting the back panel high-current terminal

New Function Output Switch. You can set the current directly without "short circuit"! Sometimes we need to switch between different voltage or current outputs, but often we forget to unplug the previous instrument, causing it to burn out, a situation that often occurs in maintenance. The output on/off key is designed to solve this problem, press the output on/off key to adjust the required voltage and current, which makes this DC power supply more secure

Upgrade High-precision Encoder Knob. Just "set" voltage and current instead of "adjust". The encoder switch replaces the potentiometer switch, the digits are switched by pressing the knob and each digit can be set in the range 0-9 by turning the knob. Makes work easier and more efficient

Stable Output, Auto Switch C.C/C.V Mode: This variable DC power supply is a low noise, low ripple adjustable high power continuous output power supply that can work at full load for long periods of time. Constant voltage and constant current modes can be switched automatically

4-Digit LED Display, Power Display. 30V 20A DC Power Supply is a professional power conditioning unit with high resolution of 0.01V and 0.001A. The backlit 4-digit LED display of the bench power supply shows the voltage current and power values more accurately and is easy to see even in low light conditions
