Electro Industries 303D AC Power Monitor

The Electro Industries 303D is a dual-output DC power supply designed for laboratory and general-purpose use, offering regulated voltage and current outputs. It is engineered for applications requiring stable and precise power delivery, such as in design, production testing, and educational environments. The unit provides two independent or tracking outputs, each capable of delivering adjustable voltage and current, with automatic crossover between constant voltage (CV) and constant current (CC) modes. Its design emphasizes regulation, low ripple and noise, and built-in protection features to ensure reliable operation and safeguard connected equipment.
