Features
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
