6.1.4 AutroVoice miniVES Charger
The Charger module is responsible for distribution of uniterrupted power supply for all internal units and auxiliary outputs.
It supplies the devices with guaranteed 42…57,6 VDC and 24 VDC.
As a main source of power it uses a switching power supply Unit; as a source of back-up power supply, it uses the VRLA battery
bankconsisting of four 12 V batteries with the capacity of up to 60 Ah.
Charger module monitors fuses and output parameters of each circuit, it maintains the battery in charged condition, ensures
temperature compensation of charging parameters and monitors series resistance of the battery and its wiring in compliance
with Exhibit No. A2 of the EN 54-4 Standard.
Charger module ensures uninterruptible switching to back-up battery power in case of main power decay or failure
of the Power Supply Unit.
Additionaly Charger module supports:
» 7 logic inputs and 3 relay outputs,
» auxiliary “BUS CTRL” port for connecting the wiring loom for two line control cards (only in the AutroVoice
miniVES 4002x series devices)
» replaceable battery for the internal system clock
» audio line in, unbalanced, with stereo to mono conversion (1 ch)
» audio line out, unbalanced (1ch for L+R out)
In order to connect the batteries to the charger use the battery cable supplied with the device. Be sure of proper connection
(polarity) between batteries and terminals. Lastly connect the thermistor temperature sensor to the “TEMP SENSOR” jack and
place it near installed batteries. Only unused and type compliant batteries (same manufacturer, equivalent capacity and voltage,
same manufacturing date) may be connected.
