Data Sheet V100 Amplifier Slide-in Panel V100 100 Watt Amplifier Fig. V100 (L- No. 2.510) At a Glance: • Amplifier for low frequency (LF) signals with max. output of 100 Watt • Standard output voltage of 100 V (optionally also 50 V or 70 V) • Short-circuit resistant • Integrated wire breakage and short-circuit monitoring (according to equipment level 2 of the Deutsche Bahn AG) The amplifier module V100 supplies an output of 100 W at 100 V output voltage. Up to 17 amplifier modules (17 x 100 W) can be used in a DVS-21 system.

The maximum output is 100 W. Different sources can act as LF signal, e.g. call stations connected to the 4NSA (manual public address) or the speech memory module DSS1 (automatic public address). The amplifier outlet can be switched directly to a loudspeaker circuit or to different loudspeaker circuits using the modules 4LSL or 4IOS. If a TG01 is used in addition to the 4LSL, then the individual loudspeaker circuits can be monitored for impedance deviations. If an amplifier fails then an emergency/disaster amplifier can take over its function. The V100 is divided into function groups: 1) 2) 3) 4) 5) 6) 7) Date: 16.03.2009 Control Codec Digital amplifier Filter Output Disaster switch Wire breakage or short-circuit monitoring Page: 2/5 Author: HS Document-No.: © 2008 ProCom, All rights and technical changes reserved DB_V100_2510_01 Data Sheet V100 Amplifier Slide-in Panel The following block diagram illustrates the functionality: V100 I n A d n iz ce ai tg ie o n +5V C S GND Ot -5V Impedanzüberwachung Impedance Monitoring e KS N u Meldung Signal Te (Z) Codec r LF NF Ru Test Signal Testton O n P C P M C BUS M g L PotentialPotential trennung Sepera- AusgangsOutput Transformer Übertrager Filter Impedance Monitoring Digital DigitalAmplifier Verstärker Impedance Monitoring 50/70/100V 48V (Short-circuit Secure) (Kurzschlussfest) V out -48V Relay 1 Relais +0V VH in HavarieDisaster Eingang Input Relay 2 Relais Block diagram V100 1) Control A microprocessor regulates timing control between the PCM bus and the module, controls message input and output and generates the audio signal required for impedance monitoring. 2) Codec The codec converts the incoming digital signal into analogue LF and passes this to the opto-coupler for potential separation. 3) Digital Amplifier The digital amplifier amplifies the potential-separated LF signal. The operating voltage of 48 V required for this is fused. 4) Filter The low-pass filter filters the amplified signal and passes it on to the output transformer.

Optionally, an adjustment to 50 V or 70 V can be made. For this all that is needed is that a jumper be soldered onto the backplane of the DVS-21 system. The signal is switched over the closed circuit contact of relay 1. 6) Disaster Switch In the case of a disruption, depending on the system, one or multiple amplifiers can be used as emergency amplifiers. One amplifier can assume the disaster function for up to 6 amplifiers. In the case of a disruption the damage relay (relay 2) and the output relay (relay 1) of the defective V100 drop out. The loudspeaker circuit of the failed amplifier is connected with the output of the disaster amplifier over the normally closed contact of relay 1. Allocation of the disaster amplifier is done using solder bridges on the backplane. 7) Wire Breakage and Short-Circuit Monitoring Output voltage and current in the loudspeaker line are measured for wire breakage and short-circuit monitoring. An error message is issued if programmed limit values are underrun or exceeded. A TG01 and a 4LSL are required for more precise monitoring of impedance in individual loudspeaker circuits.
