Avionics test instrument DBL-750

aeronautical

Product overview
The DBL-750 secondary power-supply teaching platform comprises a battery, converter, charger, load circuit, filament and Pitot tube. It is intended for aerospace training environments to convert DC into aviation-grade AC, feed representative loads and simulate aircraft de-icing and Pitot-tube heating sequences for instructional demonstrations.

Main features

• Converts 24V DC to aviation-standard 115V single-phase AC.
• Simulates aircraft de-icing operation and supplies power for Pitot-tube heating.
• Frequency simulation around 400 Hz with display accuracy ±5 Hz.
• Compact dimensions suitable for classroom and lab benches (≤600×500×900 mm).

Technical specifications

• Operating voltage: 220±15% VAC
• Output voltage: Battery 24V DC; Converter 115±10% V
• Frequency display: Range 400±20 Hz; Accuracy ±5 Hz
• Dimensions: Not exceeding 600×500×900 mm
