Introduction
PS9400 is a rack-mounted 24V DC regulated power supply with a built-in mains failure changeover relay. When the main power fails, the relay automatically switches to a 24V DC backup battery bank to keep critical PA equipment running smoothly. Designed specifically for PA system reliability, the PS9400 prevents voltage fluctuations that can occur with unregulated power supplies, protecting sensitive equipment and ensuring stable operation, making it ideal for reliable, professional installations.
Packing information
