RCF S.P.A. THANKS YOU FOR PURCHASING THIS PRODUCT, WHICH HAS BEEN
DESIGNED TO GUARANTEE RELIABILITY AND HIGH PERFORMANCES.
DESCRIPTION
PS 6048 is a backup power supply unit suitable to get continuity power supply for EN 54-
16 system units (e.g. DXT 9000 and DXT 7000EN systems).
PS 6048 needs to be equipped with lead-acid batteries and includes recharging and
monitoring functions.
INSTALLATION
Fix the unit to a 19” rack cabinet through 4 screws.
According to EN 54-16 standard, the backup power supply unit shall be installed into the
same rack cabinet where there is the audio system with emergency purposes (or a system
part) to which it is connected.
IMPORTANTE: INTERNAl juMPER sETTINg shAll bE cARRIEd OuT ONly by EIThER RcF OR AN AuThORIsEd
sERvIcE cENTRE.
In normal operating mode: the PS 6048 recharges batteries (and maintains them when
they are fully charged).
The maximum total output current that can be supplied continuously (I max a) while
charging batteries is given by:
I n: nominal output current (12 A)
C: battery capacity [A h]
19” rack - 2U

ENGLISH
I max b = I n
I max c = 150 A / 100 A
When the mains supply is available, the maximum total output current that can be
supplied for a short period of time (I max b) corresponds to the nominal value (12 A).
During this time, batteries are not charged (nor discharged).
When the mains supply is NOT available (backup operating mode), the maximum total
output current that can be supplied from batteries (I max c) is either 150 A if the internal
jumper is set to ‘75’ or 100 A if set to ‘50’.
a) I max c = 150 A
Set the internal jumper to ‘75’ and use batteries with a capacity of 86 to 225 Ah.
b) I max c = 100 A
Set the internal jumper to ‘50’ and use batteries with a capacity of 65 to 225 Ah.
The jumper factory setting is the ‘75’ position.Any other jumper setting is like the ‘50’
position.

BATTERY WIRING INSTRUCTIONS
APPROVED BATTERY MODELS:
-Yuasa NPL series
-Powersonic GB series
-ABT TM series
-Enersys VE series
-Effekta BTL series
-Long GB series.
It is advised to secure batteries with a (low resistance, gG curve) fuse, chosen according
to maximum current.
The battery temperature sensor shall be placed as close as possible to batteries, but it
does not need to be in contact with them. For example, it may be xed on the battery
cables.
The PS 6640 checks the battery resistance (including connections) every 4 hours.
The fault threshold resistance value is either 32 mΩ ±10% if the jumper is set to the ‘75’
position or 48 mΩ ±10% if set to the ‘50’ position. Exceeding this threshold is signaled
as a battery fault: batteries will not have the required backup duration in case of mains
power cut.
To avoid possible false fault indications, use battery cables as short as possible and with
large cross sections (35 mm² max).
Approximately, the resistance per metre of a cable (with two copper wires) is:
-3.6 mΩ/m (10 mm² section)
-2.3 mΩ/m (16 mm² section)
-1.5 mΩ/m (25 mm² section)
-1.1 mΩ/m (35 mm² section).

FRONT PANEL LEDS AND OPERATION
The MAINS FAULT 1is indicated when the front panel LED turns from green to yellow
and remotely by its respective (5 s) delayed dry contact (fail-safe, for remote monitoring)
when:
-The mains is not present or lower than either 185 V ac ±5% (if the charger is not
recharging) or 165 V ac ±5% (if the charger is recharging).
-The mains fuse is blown or not present.
-The charger is faulty.
-The internal temperature is too high.
Green LED: OK (no mains fault).
The BATTERY FAULT 2is indicated when the front panel LED turns from green to
yellow and remotely by its respective dry contact (fail-safe, for remote monitoring) when:
-Batteries are not present (the battery test is carried out in this way: every 30 seconds
for the rst 20 minutes after commissioning and then every 15 minutes; if a fault is
detected, batteries will have been tested every 30 seconds for 20 minutes after the fault
disappears).
-The battery internal resistance is too high (a test occurs every 4 hours when the mains
supply is present and the charger output current is lower than 12A; the resistance limit
value is 32 mΩ ±10%).
-The battery voltage is lower than 47 V ±3% (when the mains supply is present).
A voltage compensation system maintains the charge characteristics within the battery
limits across the entire operational temperature range.

ThE PROTEcTION ThREshOld, ARElAy dIscONNEcTs bATTERIEs FROM MAIN ANd AuxIlIARy OuTPuTs.
Protection from battery reverse connection:
-At start-up, the battery relay will not let the current pass.
-During operation: the F8 fuse will blow out.
If the battery voltage is either higher than 60 V ±3% or lower than 40 V ±3%, batteries
will not be connected.
Green LED: OK (no battery fault).
The OUTPUT VOLTAGE FAULT 3is indicated when the front panel LED turns
from green to yellow and remotely by its respective dry contact (fail-safe, for remote
monitoring) if there is no output voltage on one or more outputs (all nine outputs are
checked).
Green LED: OK (no output voltage fault).
