Floor power supply MX

AC/DCsingle-phasethree-phase

Overview
The California Instruments MX Series comprises floor-standing programmable AC and DC power systems designed for automated test equipment (ATE) and product test applications. Using PWM switching, the MX Series delivers high power density in compact cabinets and supports AC, DC and combined AC+DC operation in single- or three-phase output configurations depending on model.

Note
California Instruments announced End-Of-Life (EOL) for the MX Series on March 31, 2023; Last Time Buy was offered until September 30, 2023.

Operation and control
The series is operated from a menu-driven front panel with backlit LCD for setup and read-back. Standard remote interfaces include RS232C and USB; optional IEEE-488 (GPIB) and LAN are available. Programmable (Pi) controllers provide arbitrary waveform generation, advanced time/frequency measurements and waveform capture; instrument drivers and software for common ATE environments are supplied.

Key features

• High-power AC and DC source in a compact floor cabinet
• Programmable AC and DC outputs for frequency conversion and product testing
• Expandable power: per-unit outputs of 15, 22.5, 30 and 45 kVA; multi-unit configurations up to 135 kVA
• Single- and three-phase operating modes (phase-mode programming on selected 3-phase models)
• Arbitrary and harmonic waveform generation and distortion programming
• Optional regenerative (bidirectional/sink) mode returning up to 100% rated power to the utility (SNK option)
• Standard remote control: RS232C and USB; optional IEEE-488 and LAN

Voltage and current
Standard AC ranges: 150 V L-N (259 V L-L) and 300 V L-N (519 V L-L). Dual-range option (-333) provides 166 V L-N / 333 V L-N; optional -HV offers 400 V L-N (693 V L-L) AC-only range. Current capability varies by model, up to 375 A per phase for highest-power configurations.

Configurations

• MX15: up to 15 kVA, single-phase output
• MX22.5, MX30, MX45: up to 22.5, 30 and 45 kVA respectively; single- or three-phase operation in AC or AC+DC mode (in DC mode, 50% of AC power)
• MX-P models: support AC+DC mode
• MX90 and MX135: higher-power systems; -MB reconfigurable variants split into multiple MX45 units for separate applications

Features and capabilities

• Built-in output transient generation and read-back for product evaluation and test
• Advanced test functions on Pi (programmable) models: IEEE-488 and RS232C interfaces, arbitrary waveform generation, waveform acquisition and harmonic measurements
• Phase-mode switching on MX30-3Pi and MX45-3Pi to switch between single- and three-phase outputs
