Adjustable 0-60V/ 0-10A: Except a fixed 5V/3A output, this DC power supply comes with dual adjustable output within 30V/5A. You can use independently or set both in a series mode to reach up to 60V output voltage or in a parallel mode to get max. 10A output current. Automatic Tracking: Designed with master and slave circuits, the master circuit can be used to auto track the output voltage or current in the slave circuits. Easy, Continuous Adjustment: Both the current and voltage can be flexibly adjusted to a specific fixed value from 0 to 5A or 30V, no fluctuation at all. The triple linear power supply can auto switch between constant voltage and constant current mode. Reliable Protection Mechanism: Safety use is the top priority of Dr.meter. The device fully prevents both users and device itself from any risks due to its strict protection of limited current, short circuit, and more. Wide Application: Physics experiment lessons? Laboratory researches? DIY maintenance? Electronic engineering studies? Science projects? Thanks to its versatility, the DC power supply covers all of them.
