  Offering 0.03% basic voltage accuracy and 0.1% current accuracy, the 2220G-30-1 ensures avionics modules receive precise power levels during testing, crucial for the performance and safety of critical avionics systems.
  With ripple and noise under 3mVpp, the power supply provides low-noise output suitable for testing sensitive avionics equipment such as communication modules and navigation systems.
• Configurable Voltage and Current Outputs for Flexible Testing:
  The two 30V channels can be configured in series to provide up to 60V or in parallel to deliver up to 3A. This flexibility allows avionics professionals to simulate and test a variety of power scenarios, including systems like radar or high-power avionics processors.
• Remote Control and Automation with USB and GPIB:
  The 2220G-30-1 is equipped with both USB and GPIB interfaces, offering flexible connectivity options for automated test setups. The GPIB interface, in particular, allows for seamless integration with legacy avionics test systems, making it ideal for long-term testing and avionics certification processes.
  The power supply is compatible with LabView and IVI drivers for efficient control, data logging, and automation of avionics tests.
• User-Friendly Interface for Avionics Maintenance:
  The bright vacuum fluorescent display on the 2220G-30-1 ensures clear visibility of voltage and current levels, even in dimly lit environments such as maintenance hangars. The intuitive numeric keypad and rotary knob allow for quick and precise adjustments during avionics system testing.
  With 30 memory locations, frequently used configurations can be stored and easily recalled, streamlining repetitive avionics test cycles.
• Protection and Timer Features for Critical Avionics Equipment:
  The programmable output timers ensure that power is supplied to avionics components only for the specified time, protecting sensitive equipment from overexposure to power during testing. Each channel can be set with independent voltage and current limits, preventing accidental damage to avionics systems during tests.
• Compact and Durable Design for Avionics Workspaces:
  With its compact and rugged design, the 2220G-30-1 is built to meet the demanding conditions of aviation environments. It is portable, featuring protective boots and a durable handle, making it easy to use in both labs and field-testing environments.
