100 Watt Amplifier
Fig. V100 (L- No. 2.510)
At a Glance:
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.
• 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)

Application example, public address
The V100 amplifies low frequency (LF) signals of the 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) Control
2) Codec
3) Digital amplifier
4) Filter
5) Output
6) Disaster switch
7) Wire breakage or short-circuit monitoring

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.

5) Output
The output signal is adjusted per default to 100 V. 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 amplifi-
ers 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.
