Description

The Powerbox 3303DS is a compact, single-output linear DC power supply designed for laboratory testing, electronics development and equipment servicing. It provides a continuously adjustable output of 0–30 V DC at up to 3 A, delivering a maximum output power of approximately 90 W. The unit supports constant-voltage and constant-current operation with automatic operating-mode control. Its linear-regulation technology provides low ripple and noise, with specified constant-voltage ripple below 1 mV RMS. It also features a floating output and supports series connection for increased voltage or parallel connection with another identical model for increased current capacity. The Powerbox 3303DS is suitable for powering and testing circuit boards, amplifiers, sensors, communication equipment, control circuits and other electronic devices. Its stable adjustable output, digital display and straightforward operation make it useful in research laboratories, production facilities, repair workshops and educational institutions.
