The Madell TPR-3005 is a linear regulated DC power supply engineered for precision test and measurement applications. Dual adjustable outputs deliver 0–30 V DC at 0–5 A per channel, complemented by a dedicated fixed 5 V/3 A output. The supply operates in independent, series, or parallel modes—selectable via front-panel switches—enabling output voltages up to 60 V or combined currents to 10 A. Constant voltage and constant current regulation modes provide stability to ±0.01% + 2 mV (at ≤3 A) with ripple below 0.5 mVrms. Comprehensive protection includes overload, short-circuit, overheat, and overvoltage circuits. Dual digital displays monitor output voltage and current in real time. Low noise performance, fast transient restore (≤100 µs), and minimal temperature drift (≤300 ppm/°C) support demanding laboratory and production environments. AC input accepts 110 V ±10% 60 Hz or 220 V ±10% 50 Hz.
