The Extech 382275 power supply is an easy-to-configure, extremely stable, lab-grade DC power supply with a maximum output power of 600 W. The new DC power supply provides two levels of control for both current and voltage outputs (course and fine). The output ranges from 0 to 30 volts DC and 0 to 20 amps (with a precision of 0.1 volts per amp). Dual green LED displays provide clear, high-contrast readouts of voltage and current measurements. The 382275 has four operating modes: normal mode, with values controlled by front-panel knobs; preset mode, which offers three popular voltage presets at 20 Amps: 5.0 Volts, 13.8 Volts, and 25 Volts; set mode, with three user-customizable presets; and remote control mode, which allows the user to remotely adjust output power on/off, voltage.
