The Kepco ATE55-5M is a precision analog-controlled half-rack DC power supply delivering 0–55V at 0–5A (250W) with automatic voltage and current stabilization. Independent front-panel potentiometers provide full-range output control, while dual analog meters continuously display voltage and current. A linear NPN pass transistor section driven by high-gain IC amplifiers ensures stable, low-noise operation. Selectable slow and fast modes accommodate constant-voltage applications and rapid transient response respectively. The slow mode achieves <0.1mV RMS ripple and <1mV peak-to-peak noise.
