The California Instruments MX90-3/Pi Test System 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 California Instruments MX90-3/Pi Test System combines compactness, robustness and functionality in a compact floor-standing chassis. This higher power density has been accomplished without the need to resort to elaborate cooling schemes or additional installation wiring. Simply roll the unit to its designated location (using included casters), plug it in, and the California Instruments MX90-3/Pi Test System is ready to work for you.

The California Instruments MX90-3/Pi Test System can be operated completely from its menu driven front panel controller. A backlit LCD display shows menus, setup data, and read-back measurements. IEEE-488, RS232C, USB and LAN remote control interfaces and instrument drivers for popular ATE programming environments are available. This allows the California Instruments MX90-3/Pi to be easily integrated into an automated test system. For advanced test applications, the California Instruments MX90-3/Pi Test System, with its programmable controller, offers full arbitrary waveform generation, time and frequency domain measurements, and voltage and current waveform capture.

The California Instruments MX90-3/Pi Test System delivers up to 90 kVA of single phase output. It allows switching between single and three phase output modes. In DC mode, 65% of the AC power level is available and AC + DC mode is also supported. The built-in output transient generation and read-back measurement capability of the MX90-3/Pi offers the convenience of a powerful, and easy to use, integrated test system.
