Amplifiers & AccessoriesDPA / BECSD-Class Power Amplifiers, 19”- EN54-16DPA four characteristics• DPA four 125: 4 x 125 Watt class-D power amplifier.Can be bridged into 2 x 250 W.• DPA four 250: 4 x 250 Watt class-D power amplifier.Can be bridged into 2 x 500 W.• DPA single 1000: 1 x 1000 Watt class-Dpower amplifier.• 2U high, 19-inch rack mountable.• Quiescent current in sleep mode: 30 mA.Security Amplifiers, EN 54-16The DPAfour is a 2U high 19” rack mountable,4-channel class-D power amplifier, transformer isolatedfor 100 V, 70 V, 50 V and low-impedance distributedloudspeaker systems. Each amplifier can deliver up to1000 Watt when used in bridged mode or in separatechannels of 125 or 250 Watt.DPAfour1254 x 125 Watt class-D power amplifierThis amplifier has a dual voltage mains 110/230 VACand a 24 VDC battery back-up input which allows it tobe used in combination with a battery backup systemfor maximum availability and durability in an emergencyevacuation system. There are 3 types of power amplifiersavailable in the DPA four range of products.DPAfour2504 x 250 Watt class-D power amplifier• Front panel indicators include:General status: Power, Battery, Service and GeneralFault. Detailed status: Signal, Clip , Fault andReady (Ready = out of sleep mode).• 100 / 70 / 50 / 4 Ohm available via terminal blocksat the rear.• Output channels can be linked into 2 x 250 Wor 2 x 500 W by daisy-chaining 50 V tapping (inputon parallel).• Combines with the BECS150 chargerand back-up supply.DPAsingle10001 x 1000 Watt class-D power amplifierCharger and monitoring unit for DPA-amplifier series, EN 54-4The BECS150 is a combined security battery charger andbackup supply for the DPA four family of products. TheBECS150 provides power backup during mains failure toa maximum of 6 DPA four power amplifiers and 1 backuppower amplifier. The BECS150 is equipped with heavy dutypower connectors and an isolated main battery entry forextra safety during installation. All outputs are electronicallyfused (40 A).Beside a charger for a 150 AH 24 VDC battery, theBECS150 is also equipped with a separate 150 Watt 24VDC power supply that acts as redundant backup forthe individual DPA four power amplifiers in case of aninternal power supply failure. In that case, the amplifiersare forced into sleep-mode and will continue withloudspeakerline surveillance. In case of an EVAC, theamplifiers will be forced alive for duty using the batteryback-upsupply. (Commercial use still disabled). This waythe batteries are secured for emergency applicationswith a maximum availablility for the amplifiers.BECS150Charger and monitoring unit for DPA-amplifier series for upto 6 DPAfour plus back-up amplifier and battery surveillanceand charger unit.BECS150 characteristics• 2 U high, 19-inch rack mountable.• Battery capacity: 150 AH (4x 12VDC/75AH)• 6 x 24 VDC secured outputs for DPA fourpower amplifiers.• 1x 24 VDC secured output for DPAxx back-uppower amplifier.• 3 x 24 VDC outputs for IDA4 Series, IDA8 Seriesand DIVA8 Series of routing units.• Redundant 150 W / 24 VDC powersupply.• Separate Charger for 150 AH battery.• BECS/RK - Battery charger accessory -19’’/6U Rackframe for 12VDC/75 AH batteries x4.Max carrying weight: 150 kg27
