About this product
MAISEN MS-3010D is a benchtop adjustable DC power supply with coarse and fine controls for voltage and current. It switches automatically between constant-voltage and constant-current modes and includes overvoltage, short-circuit and over-temperature protection, suited to electronics prototyping and repair.

Frequently asked questions
How do I set the current limit before connecting a load?
Short the output terminals, set the desired current limit and voltage, then remove the short and connect the load. The supply will switch to constant-current mode if the load draws more than the set limit.
What does the automatic CV/CC switching do?
The supply works as a constant-voltage source under normal loads and as a constant-current source when the load tries to draw more than the set current limit, which helps protect the circuit under test.
