DPA 8000 Power Amplifier

The DPA 8000 Series power amplifiers are Class-D amplifiers which have been designed for AC mains as well as for DC
operation. The output voltage is galvanically isolated and constantly monitored for ground fault. A power saving mode
and temperature controlled fans allow for energy efficient and nearly noiseless operation. Control and monitoring are
carried out via the REMOTE CAN BUS. The amplifiers have been designed for use in an evacuation system. Control
usually is taken care of by the DPM 8016 Paging Manager and the configuration by means of IRIS-Net. If amplifiers are
operated without employing a DPM 8016, the configuration can be created in IRIS-Net and permanently be stored in
the amplifier, so that the desired state (preset) is activated, each time the device is powered ON.
All power amplifiers have the following common features:
– Floating 100 V power outputs (internally configurable to 70 or 50 V)
– Amplifier blocks in Class-D technology
– Outputs are protected against idling and short-circuit
– Mains operation 230 V/120 V AC and/or 24 V DC emergency power
– Electronically balanced inputs
– Temperature monitoring
– Pilot tone and ground fault monitoring
– Fault message via floating READY contact
– All functions are processor-controlled
– Watchdog circuit for monitoring the processor system
– Nonvolatile FLASH memory for storing the configuration data
– Internal monitoring
– Integrated audio relays
– Line monitoring
DPA 8000 Device
Start by creating an DPA Device in your IRIS-Net project. Drag an DPA from the Object Bar's Devices category or from
the Devices window into the worksheet (see also chapters: Devices and Configurations menu). The following dialog
box appears:
