Key Features:

• Independent, Isolated Channels for Sensitive Avionics Components:
  The 2220-30-1 is designed with two independent and isolated channels, each capable of delivering up to 30V and 1.5A. This makes it ideal for powering circuits with different ground references, such as those found in avionics systems. It is especially useful when testing multiple subsystems in parallel, ensuring that sensitive avionics components are not subjected to electrical interference from other circuits.
• High Accuracy and Stability for Precision Avionics Testing:
  The power supply provides 0.03% basic voltage accuracy and 0.1% current accuracy, ensuring that avionics modules receive exact power levels during testing. This precision is critical for avionics systems that must meet strict safety and performance standards.
  With low noise regulation and ripple kept under 3mVpp, the Keithley 2220-30-1 delivers clean and stable power, essential for testing avionics components such as communication modules, navigation systems, and other high-sensitivity equipment.
• Configurable Voltage and Current Outputs for Flexible Testing:
  The two 30V channels can be combined in series to provide up to 60V or in parallel to deliver up to 3A, offering flexibility for various avionics testing scenarios. This feature allows aviation professionals to test systems requiring higher voltage or current levels, such as radar systems or power-hungry avionics processors, ensuring they perform within operational limits.
• Remote Control and Automation for Efficient Avionics Testing:
  Equipped with a USB interface for remote control, the Keithley 2220-30-1 can be easily integrated into automated test systems commonly used in avionics laboratories. This is essential for repetitive testing cycles, allowing aviation maintenance professionals to perform long-duration tests without manual intervention. Optional GPIB interfaces provide additional flexibility for integration into legacy avionics test setups.
  The power supply is compatible with LabView and IVI drivers, enabling efficient data logging and automated test procedures that are vital for avionics certification processes.
• User-Friendly Interface for Avionics Maintenance:
  The intuitive front panel design, with a vacuum fluorescent display, provides easy-to-read output values, ensuring that voltage and current levels are clearly visible even under the dim lighting conditions often found in maintenance hangars. The numeric keypad and rotary knob allow for fast and precise setting of test parameters, streamlining avionics system checks.
  30 memory locations enable the storage of frequently used configurations, making it easy to switch between different avionics tests, such as those for navigation, communication, and flight control systems.
• Protection and Safety for Critical Avionics Equipment:
  The Keithley 2220-30-1 includes programmable output timers to ensure that power is only supplied to avionics components for a pre-defined period, protecting sensitive equipment from overexposure to power during long test cycles. Each channel can also be configured with independent voltage or current limits, safeguarding critical avionics systems from accidental over-voltage or over-current conditions.
• Compact and Durable Design for Avionics Workspaces:
  Built to withstand the demands of aviation environments, the Keithley 2220-30-1 features a compact, rugged design that fits seamlessly into avionics testing benches. Its portability, protective boots, and durable handle make it suitable for use in maintenance labs, hangars, and field-testing scenarios.

Applications in Avionics Testing:

• Powering Avionics Communication Systems: Test and validate radios, transponders, and communication modules that require precise, noise-free power.
• Testing Navigation and Flight Control Systems: Ensure the accuracy and reliability of GPS modules, gyroscopes, and other navigation components that are essential for safe flight operations.
• Simulating Power Variations in Avionics Modules: Use series or parallel configurations to simulate different power conditions in systems like radar, autopilot, and avionics control processors.
• Automated Test Systems for Avionics Certification: Integrate with automated test setups to streamline avionics certification processes, ensuring compliance with stringent aerospace industry standards.

With its advanced features tailored for the demanding environment of avionics testing, the Keithley 2220-30-1 Dual Channel DC Power Supply is an indispensable tool for aviation maintenance professionals and avionics engineers, providing the precision, reliability, and flexibility required to ensure the safety and performance of critical avionics systems.
