California Instruments RS270 High Power AC&DC Power Source 270kVA

Description

The RS 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 RS 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 RS unit to its designated location (using included casters), plug it in, and the RS series is ready to work for you.
