Description
Within a VARIODYN D1 voice alarm system this amplifier occupies the power stage, offering four independent power channels. Set against the 4XDxxxB series amplifiers, one amplifier is able to back up others.
The 2HU 19" case is 484 mm wide, 88 mm high and 400 mm deep, weighs approx. 13.8 kg and is finished in gray, similar to RAL 7016. Operation is rated for an ambient temperature of -5 °C ... 55 °C and air humidity of 40 ... 93 %.
The 580248.11 is the four-channel amplifier 4XD300, a power amplifier for the VARIODYN D1 voice alarm system built in Class D technology. Its four independent power channels give a power output of 4 x 300 W, taken from symmetric inputs and delivered through galvanically isolated 100 V direct outputs. Inrush current limitation and soft start are part of the same design.
Mains operation is at a rated voltage of 230 V AC, the rated frequency spanning 50 ... 60 Hz (+10 % / -5 %), and 24 V DC serves as the emergency power supply. Channel separation reaches > 92 dB, and harmonic distortion at nominal level sits at < 0.02 %.
