Power Supplies

New! Manson SPS-9620 120A regulated power supply

Super high current!
=Sold=

Super high current power supply for high power linear amplifiers, etc.

Regulated 13.8Vdc output, 120 amp current power supply
Finely adjustable output voltage: 12.6 to 14.3VDC
Ripple and noise: 40mV p-p
Regulation 0.1% + 5mV
Variable speed thermostatically controlled fan
Overload (constant current limiting), short circuit, over-temperature and over-voltage protection features
Constant current limiting allows output current to remain constant but the output voltage reduces to a safe level
Remote sensing feature
