NICE-POWER Dual DC Power Supply Variable: 30V 10A 300W Adjustable Switching Regulated Series (60V 10A 600W) Parallel (30V 20A 600W) High Precision 5V/2A USB Port Bench Lab Power Supplies — Open-Box, 7% Off

4 in 1 DC Power Supply: Dual DC power supply meets the needs of multiple power supply specifications at one time, one dual DC power supply is equal to two 30V10A power supply/one 30V20A/one 60V10A power supply, which meets the needs of multiple operations, and can also be used as a high-power use at the same time. You no longer need to manually connect two DC power supplies in series or parallel.

CE & FCC Certification, Multiple Protection, Various Application: DC power supply have passed CE & FCC Certification. DC power supply variable has multiple protections: overvoltage protection, overcurrent protection, overheating protection, over power protection, short circuit protection, leakage protection. DC power supply is suitable for battery charging, arduino project, anodizing, laboratories, schools, electronic maintenance , electrolysis, electroplating, lamp test, DIY, and other electrical equipment.

Series and Parallel Function: It is very convenient to add series and parallel function, press "INDEP" which is two 30V 10A lab power supply, press "SER" button of dual power supply, you will have one 60V 10A power supply, press "PAR" button of dual power supply, you will have one 60V 10A power supply. Pressing the "PAR" button will switch to a 30V 20A power supply. This will satisfy your need for a higher voltage or higher current. It saves you the time for DC power supply, which is a good helper in your work!

4-Digits LED Display, Encoder Precision Adjustment: Our DC power supply voltage and current values are accurate to 0.01V and 0.01A, and the encoder is used to more accurately regulate the desired current and voltage, and the refinement is made to the extreme! Two sets of encoder knobs, when the power supply is in INDEP state, you can separately adjust the current and voltage values on both sides.

Compact Design, Quality Check, Terms of Service: the size of the bench power supply is only 15.3 * 7.3 * 8.7 inches, the weight is only 6.6 lbs, which saves you more bench space, easy to carry with you when you need. Delivery includes: dc power supply*1; power cord*1; English manual*1; low power output cable*2. If you have any questions about our lab DC power supply, please contact us and we will reply within 24 hours.

4-in-1 DC Power Supply: Dual DC power supply simultaneously accommodates multiple voltage requirements through flexible configurations - equivalent to two 30V/10A supplies, one 30V/20A output, or one 60V/10A high-power unit. DC power supply eliminates manual series/parallel connections between separate power supplies while maintaining full operation mode compatibility for diverse applications. Certified Safe & Versatile: DC power supply has passed CE/FCC Certification. DC power supply features comprehensive safeguards including overvoltage (OVP), overcurrent (OCP), overheating (OTP), overpower (OPP), short-circuit (SCP), and leakage protection. DC power supply is engineered for professional and educational environments, it reliably powers battery charging, anodizing, lab experiments, school workshops, electronic maintenance, electrolysis, electroplating, lamp testing, DIY, and other electrical systems. Series-Parallel Operation Simplified: Instantly switch between modes using panel controls - pressing "INDEP" activates two independent 30V/10A outputs; "SER" creates 60V/10A series configuration; "PAR" delivers 30V/20A parallel operation. Achieve higher voltage or current demands without manual wiring. This intelligent switching system streamlines workflows for electronics testing, R&D, and industrial applications. Precision 4-Digit LED Display & Encoder Control: Dual DC power supply features dual-channel 0.01V/0.01A resolution with industrial-grade encoders for micro-adjustments. In INDEP mode, dual knobs enable simultaneous calibration of both channels' voltage/current. Achieves laboratory-grade accuracy through optimized signal processing algorithms.
