DC power supply MPS270
The MPS-270 is a linear DC power supply with 3 channels, 195W to 315W output. In constant voltage and current operations, the power supply provides high regulation and low ripple & noise. Auto series and parallel operations double output voltage and current.
Heat sink and automatic cooling fan control give sufficient cooling to the power supply and minimize fan noise. The output ON/OFF control and preset voltage & current function protects the power supply and related loads from unexpected damage. The MPS-270 is widely used in powering operational amplifiers, push-pull stages, logic circuits, and definition systems.
