描述

The 1735A is a high-quality, general-purpose DC power supply designed for laboratory and bench testing applications. It provides an output voltage range of 0-30V with a maximum output current of 0-3A, featuring dual analog controls with coarse and fine adjustment capabilities. The unit incorporates 4-digit LED metering with a voltmeter accuracy of ±0.5% (reading + 9 digits) and ammeter accuracy of ±0.5% (reading + 9 digits), enabling precise voltage and current monitoring. In constant voltage operation, the 1735A delivers exceptional regulation with line regulation of <0.01% + 3mV and load regulation of <0.01% + 3mV, combined with ripple and noise below 1mV rms. The power supply includes comprehensive protection features such as current limiting, reverse polarity protection, overvoltage protection, and short-circuit protection, making it suitable for educational, research, and industrial testing environments where reliable and accurate power delivery is essential.
