01-0790101-02 – Whelen 9010102 Single Flash 24 Joule Power Supply

Available now on the Airparts.aero Marketplace.

Overview

The Whelen 01-0790101-02 is a genuine OEM, high-energy strobe light power supply, a flight-critical component at the heart of many aircraft anti-collision lighting systems. This robust, remote-mounted unit is designed to convert the aircraft's 28 VDC electrical power into the high-voltage energy required to fire two remote xenon flash tubes. With a powerful 24 Joule output, this single-flash power supply produces an intensely brilliant flash of light, ensuring your aircraft is highly conspicuous in all flight conditions. As a TSO-certified product from Whelen, the world leader in aerospace lighting, it guarantees exceptional reliability and performance.

Key Features

• High-Energy 24 Joule Output: Delivers a powerful 24 Joule energy discharge to the flash tubes. This high energy level creates an extremely bright, attention-getting flash that is critical for daytime and nighttime visibility, significantly enhancing flight safety.
  
• Dual Outlet Capability: Features two outlets, allowing a single power supply to drive two separate strobe light heads simultaneously, such as those on the wingtips or tail of an aircraft.
• Solid-State Reliability: Utilizes modern, solid-state electronics for the inverter and trigger circuits. The entire unit is typically encapsulated (potted) in a rugged aluminum housing, providing superior resistance to the moisture and high-vibration environment of an airframe.
• Radio Frequency Interference (RFI) Shielding: The robust metal enclosure and internal filtering are designed to contain the high-frequency electromagnetic energy generated by the strobe circuit, preventing interference with the aircraft's communication and navigation radios.
• FAA TSO Certified: Fully certified to FAA TSO-C96a standards for anti-collision strobe lights, ensuring it meets the most stringent requirements for light intensity, flash rate, and reliability.

The Whelen 01-0790101-02 is a capacitor-discharge power supply. Internally, it first uses an inverter to step up the aircraft's 28 VDC to approximately 450-500 VDC. This high-voltage DC is used to charge a large energy storage capacitor. The 24 Joule rating is a measure of the energy stored in this capacitor, calculated by the formula

, where C is the capacitance and V is the voltage. When commanded by the timing circuit, a separate trigger circuit sends a very high-voltage, low-current pulse (thousands of volts) to the trigger wire of the xenon flash tube. This pulse ionizes the xenon gas, making it conductive. The main storage capacitor then instantly discharges its 24 Joules of energy through the ionized gas, resulting in a massive current flow that creates the brilliant, instantaneous flash of light.

Note: This is a high-voltage system component that can store a lethal electrical charge long after power has been removed. Installation and servicing must be performed by a certified A&P mechanic or avionics technician who is familiar with the safety precautions for high-voltage strobe systems. All connections must be clean and secure to prevent arcing.
