IMPACT DCA 2.500 - D-Class Charger Amplifier
The IMPACT
on the batteries
The IMPACT DCA-2.500 Is a compact 2U, 19”, 2-channel Class-D transformer isolated power amplifier for 100 V and 50 V distributed loudspeaker systems. The amplifier outputs can be bridged into a staggering 1000 W. The in-built EN54-4 compliant scalable battery charger with a temperature sensor makes this amplifier the FIRST EN54-4 certified in the market.
The DCA-2.500 D-Class amplifier provides powerful audio amplification certified to EN54-16 and EN54-4. It delivers 2x500 W outputs and is housed in a 2U 19-inch rackhousing.
Standing apart from any conventional power amplifier, the DCA-2.500 features an in-built scalable battery charger with a temperature sensor that is EN54-4 compliant.
Up to three DCA-2.500 amplifiers can be stacked together sharing a single battery pack, providing back-up power and recharging capabilities.
The amplifier has been designed along 'old-school' lines and features a transformer isolated with 100 V and 50 V outputs for distributed loudspeaker systems. It can also run in bridge-mode to produce a staggering 1000 W. With cutting edge design the DCA amplifier sets a standard for the most demanding projects.
The DCA-2.500 boasts a dual voltage mains supply combined with a secondary 24 VDC battery backup, crucial for ultimate reliability and durability in a VACIE system.
A Master/Slave system architecture, dictated by the AMP-LINK, regulates the battery charging procedure and status control.
The AMP-LINK module offers a local analogue AUX entry for local music playback into channel A and/or B. This allows for third party Commercial use integration, hence still complying to the VACIE standards.
