The document describes the output modes, specifications, and characteristics of a multi-channel power supply. It features adjustable voltage and current outputs, tracking voltage, and parallel operation. Additionally, the document provides performance specifications such as line regulation, load regulation, ripple, and noise.
The Tenma Quad‑Output DC Power Supply provides four independent DC outputs with selectable voltage and current displays, auto series/parallel/tracking operation, and protection features such as overload and reverse polarity. It includes LED indicators, fan speed control based on heatsink temperature, and enable/disable output control.
The document lists detailed electrical specifications for each channel, including voltage and current ranges, line and load regulation, ripple and noise limits, as well as mechanical data such as dimensions, weight, power source options, and included accessories.
