1. INTRODUCTION
The SR100A range is designed for use as a very accurate AC to DC power supply, or float charger for lead
acid batteries. Note that for float charging the output voltage must be set to approximately 15% above the
nominal battery voltage. This is done as the default voltage for the 12V model but must be specified at
time of order for all higher voltage models.
2. CONNECTIONS
If used as a float charger always connect the positive output of the power supply to the positive terminal of
the battery. The charger may be permanently connected to float charge lead acid batteries but it is essen-
tial to periodically check the electrolyte level of flooded cells as there is always some evaporation.
To minimize the volt drop at the output connections use all the terminals provided ie. connect output wires in
parallel.

Two or more SRxxx A series power supplies may be connected in parallel for increased power (with or without di-
odes). It is essential that the wiring from each unit to the load is kept identical for equal power sharing particularly
when diodes are not used.
Two or more SRxxx D series power supplies (standard PSU with alarms), may be connected in parallel for N+1 redun-
dancy using output diodes shown.
Diodes can be fitted inside some power supplies (see models listed below).
The SRxxx P series identifies when an internal diode is fitted in the power supply.
CONNECTION FOR PARALLEL REDUNDANCY
INTERNAL diodes can be fitted to the following
models only (diode is fitted in negative line):
100W: SR100P24, SR100P36,
SR100P48
250W: SR250P24, SR250P30,
SR250P36, SR250P48, SR250P60
All other models have diodes external to the
power supply, eg fitted into a 2U rack as shown
in the photo to the right. 2U rack with 2 x SR250D12 power
supplies and decoupling diodes on

Safety
The user is responsible for ensuring that input and output wiring segregation complies with local standards and that in
the use of the equipment, access is confined to operators and service personnel. A low resistance earth connection is
essential to ensure safety and additionally, satisfactory EMI suppression (see below).
HAZARDOUS VOLTAGES EXIST WITHIN A POWER SUPPLY ENCLOSURE AND ANY REPAIRS MUST
BE CARRIED OUT BY A QUALIFIED SERVICEPERSON.
Electrical Strength Tests
Components within the power supply responsible for providing the safety barrier between input and output are con-
structed to provide electrical isolation as required by the relevant standard. However EMI filtering components could be
damaged as result of excessively long high voltage tests between input, output and ground. Please contact our techni-
cians for advice regarding electric strength tests.
Earth Leakage
The EMI suppression circuits causes earth leakage currents which may be to the maximum allowable of 3.5mA.
Ventilation
High operating temperature is a major cause of power supply failures, for example it has been well documented that a
10
o
C rise in the operating temperature of a component will halve its expected life. Therefore always ensure that there is
adequate ventilation for the equipment. Batteries and cooling fans also suffer shortened lifetimes if subjected to high
ambient temperatures - both should be included in a routine maintenance schedule to check for signs of reduced effi-
ciency.
Water / Dust
Every effort must be made in the installation to minimise the risk of ingress of water or dust. Water will almost always
cause instant failure. The effects of dust are slower in causing failure of electronic equipment but all electrical equip-
ment should be cleaned free of any dust accumulation at regular intervals.
Electro agnetic Interference (EMI)
Switching power supplies and converters inherently generate electrical noise. All wiring should be as short as practica-
ble and segregated from all equipment wiring which is sensitive to EMI. Residual noise can be reduced by looping DC
wiring through ferrite cable sleeves. These are most effective as close to the power supply as possible and as many
turns of the wire taken through the core (+ and - in the same direction) as the core will accommodate.
Fuse ratings
Check that the wiring and fuses or MCBs match the rating of the PSU or converter. Note that the Innovative Energies
No-Break
TM
DC chargers are able to deliver up to 2.5 times the rated current when mains power is on.
Connection polarity
It is critical to check the polarity carefully when connecting DC devices. Some Innovative Energies models have re-
verse polarity protection (RPP), for example, the Smartchargers have electronic (non-destructive) RPP, the No-Break
TM
DC range has an internal fuse which needs to be replaced if the battery is connected in reverse. Usually, however, a
reverse polarity connection results in instant destruction of the device, especially if there is a battery involved.
PSU = power supply unit BCT = battery condition test ECB = electronic circuit breaker
ELVD = electronic low voltage disconnect RPP = reverse polarity protection EMI = electromagnetic interference
