⭕ This is a California Instruments MX30-3PI High Output AC/DC Power Source. This source has options HV (adds 400V AC Only Output Range), 411 (IEC 1000-4-11 test firmware), and 413 (IEC 1000-4-13 Harmonics and Interharmonics test firmware) installed. Clean condition, good working order. Less than 3 years old. This source is capable of 30KVA AC Output Power, can operate in single- and three-phase output, and Pi models include IEEE-488 and RS232C interfaces, Advanced measurements, arbitrary waveform generation. Phase mode switching is also a feature on this model. The MX Series consists of multiple high power AC and DC power systems that provide controlled AC and DC output for ATE and product test applications. This high power AC and DC test system covers a wide spectrum of AC and DC power applications at an affordable cost. Using state-of-the-art PWM switching techniques, the MX series combines compactness, robustness and functionality in a compact floor-standing chassis, no larger than a typical office copying machine. This higher power density has been accomplished without the need to resort to elaborate cooling schemes or additional installation wiring. Simply roll the MX3 unit to its designated location (using included casters), plug it in, and the MX series is ready to work for you. Delivery or local pickup can be arranged.
