– Key Features
Protection
Over-voltage, over-current, under-voltage limit, and overtemperature protection safeguard connected devices and the supply itself.
Interfaces
GPIB, LAN (LXI Class C), and USB with integrated web server enable local and remote operation and monitoring.
Mechanical Design
Compact 1U form factor, 19-inch width, front-to-back airflow optimizes integration into dense rack configurations.
Operating Range
• Temperature: 0°C to 40°C (100% load)
• Humidity: Up to 90% RH (non-condensing)
• Altitude: Up to 3000 m (current derated 2% per 100 m above 2000 m)
– Typical Applications
Component and module testing, high-current device characterization, production ATE systems, and research environments demanding stable, programmable power with integrated monitoring.
– Configuration Options
Up to 4 units operate in parallel for higher current delivery. Two similarly rated units cascade in series for increased output voltage.
