– Key Features
• 10-turn potentiometers for manual voltage and current adjustment
• Simultaneous real-time display of voltage and current settings
• Push-button controls for output standby, OVP reset, and remote/local mode selection
• Status preview for voltage, current, and OVP setpoints
• LED indicators for overtemperature, remote programming, shutdown, overvoltage protection, operating mode, and constant-voltage/constant-current operation
• Remote sensing capability to compensate for power lead voltage drop (maximum 4 V per sense line)
• High power density in low-profile chassis design
– Remote Programming and Interfaces
The M9C option integrates an internal IEEE-488/RS-232 interface for 12-bit remote programming of voltage, current, and OVP. This configuration cannot be combined with M51A or M85 options. Alternative interface options include the M130 (LXI-compliant Ethernet with 16-bit programming and web server access) and M51 (isolated analog programming with isolated V/I monitor outputs up to 500 V relative to return).
– Typical Applications
Ideal for test automation, component characterization, power conditioning evaluation, and production ATE environments where precise DC output and system integration are required.
