• Temperature coefficient (constant voltage): <0.03% + 10 mV per °C
• Transient recovery time: <200 µs to within 600 mV of nominal output
**Power Input:** 110 Vac, single phase. Option 005 enables 50 Hz operation.
## Key Features
• Front-panel banana jack outputs (positive, negative, ground) suitable for loads <3A
• Remote programming via resistance or external voltage source
• Remote sensing for load-dependent accuracy optimization
• Auto-parallel, auto-series, and auto-tracking support for multi-supply configurations
• Metered voltage and current display
## Interfaces
Front-panel banana jacks provide direct local control. Remote programming and sensing inputs enable integration into automated test systems and external control architectures. Multiple supply configurations support parallel stacking and series connection modes.
## Typical Applications
The 6439B suits high-current DC testing, power amplifier characterization, industrial motor drive validation, and bench-level device qualification requiring stable, adjustable DC power with moderate regulation performance.
