The Astron N2412-24 DC to DC Voltage Converter is designed to provide reliable step-down voltage conversion from higher-voltage DC electrical systems to a regulated 13.8 VDC output. It accepts an input voltage range of 28 to 14 VDC and delivers up to 24 amps of output current, making it suitable for powering 12-volt equipment from 24-volt aircraft or vehicle electrical systems.
This converter uses high-frequency pulse modulation at 20 kHz to achieve efficient voltage regulation while maintaining stable output under varying load conditions. It is designed without electrical isolation between the input and output negative terminals, allowing straightforward integration into negative-ground electrical systems.
The N2412-24 incorporates multiple protection features, including over-voltage and short-circuit protection, input-side over-voltage and transient suppression, and reverse polarity protection. These safeguards help protect both the converter and connected equipment during normal operation and abnormal electrical conditions.
The unit is commonly used to supply 13.8 VDC power to FM transceivers and other avionics or electronic devices requiring a stable 12-volt source when operating from a 24-volt battery system.
