The Lambda LA-350 is a regulated DC power supply delivering up to 112 W at 3.5 A, engineered for laboratory, industrial, and commercial test environments. Front-panel potentiometers govern output voltage and adjustable current limiting across the full load range. Separate analog meters display voltage and current; a dual-state LED indicator shows constant-voltage or current-limit operation. The supply accepts 85–132 VAC (47–440 Hz) or 110–165 VDC input and operates continuously from 0 to 50 °C without derating. Convection cooling eliminates the need for forced-air circulation. TTL-compatible remote on/off control and heavy-duty binding posts support both bench and integrated system configurations.
