Main highlights- Wide Range of Charging Applications, Multiple Protection: The DC power supply has a maximum voltage of 30V, and can charge batteries below 30V, such as 6V/12V/24V batteries. With a maximum current of 30A and a maximum power of 900W, the DC power supply can quickly charge batteries. It has multiple protection functions such as over-temperature protection, over-current protection and short-circuit protection, which makes your charging safer.
- Terms of Service: When you buy a DC power supply you get 1* DC power supply, 1 set of output power cables, 1* input power cable, 1* user manual. If you have any questions, you can contact us at any time.
- Memory Storage, Lock Button: DC power supply variable with 3 sets of data storage buttons, you can set the commonly used data for storage, turn on the DC power supply again can be used with one key, very convenient. The lock button prevents you from accidentally touching other buttons to avoid re-adjustment.
- Encoder Adjustment Knob, Output Switch: The encoder adjustment knob can be used to precisely regulate the voltage and current. Press the knob to determine the number of digits to be regulated and rotate the pushbutton to regulate the desired voltage/current value. The output switch controls the output of the DC power supply and prevents damage to the load.
- Designed for Battery Charging: The DC Power Supply Variable has 3 charging indicators and a "Battery" button. Pressing the "Battery" button puts the DC power supply in battery charging mode. If the charging circuit is incorrectly connected, the "Check" indicator will illuminate." The "Charging" indicator light indicates that charging is in progress." The "Full" indicator lights up to indicate that charging is complete and the output can be turned off.

NICE-POWERNICE-POWER DC Power Supply Variable, 30V 30A 900W High Power Bench Power Supply with Encoder Knob and Output Switch, Lab Power Supply Adjustable Switching Regulated Power Supply Battery Charging
Main highlights- 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
- Please note: 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
- Output Switch Control: 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
- Multiple Protection, Intelligent Cooling Fan, Reliable and Safe: The DC power supply has built-in overvoltage protection, overcurrent protection, overheating protection and termination protection. When the operating temperature of the DC power supply exceeds 122°F/50°C, the fan will turn on intelligently to dissipate heat effectively and extend the life of the device. DC power supply has shock absorbing rubber feet at the bottom for safer and more stable use
- Compact Design, Quality Check: The bench power supply measures only 38*24*13cm and weighs only 3kg, saving you more bench space and making it easy to carry around when you need it. Delivery includes: DC power supply *1; American standard power cord *1; English manual; low-power output cable *1; high-power output cable *1. We offer a 12-month repair policy. If you have any questions about our lab DC power supplies, please contact us and we will reply within 24 hours
- CE & FCC Certification, Widely Used: 30v 30a Lab power supplies have passed CE & FCC Certification. This benchtop power supply is suitable for battery charging ( such as batteries with different voltages like 6V, 12V or 24V), labs, schools, electronics repair, electrolysis, electroplating, lamp testing, aging testing, DIY, research and teaching
- 4-Digit LED Display, Power Display: 30v 30a 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
