The DPP4004 PA power supply rack-unit is designed to provide the supply
voltage of 24 V DC (up to 4 amp capacity) for any ProAnnounce

™

system.The

power supply provides all the functions that modern PA systems require,
including: automatic and gapless switching between primary and battery supply
as well as remote ON/OFF-functions. During normal operation, the primary
output is connected to the internal switch-mode power supply. In case of
temporary power-loss, power-failure, or malfunctioning of the switch-mode
power supply, this output is switched to battery supply almost instantaneously,
providing uninterrupted power supply for all connected devices.When the mains supply 
is restored, the unit automatically returns with a delay of 600 ms to mains operation.
