Introduction
Switching chargers of the SP-R series are intended for charging station batteries of
nominal voltage 110V and 220V.
Chargers are suitable for supplying DC circuits with combination of charging station
batteries. Switching chargers of the SP-R series fully comply with the requirements of the
station battery charging standard EUROBAT.
Power supply unit offers function of temperature compensation of charging voltage,
inputs wiring resistance measurement or fast charging. Different charging characteristics can
be used- IU0, IUU0 etc.

Description
The power unit is fit into 3U 19`` rack and is designed for built-in mount into
switchgears. All connection and signalling points are situated in front panel.
Compact construction of the charger brings all advantage of switching units in
comparison with standard power supply unites equipped with transformer – primarily lower
weight and smaller dimensions. Advanced software equipment leads to higher user comfort
and to the merging different measure devices into one device.
Nominal output current is 50A for voltage 110V DC and 25A for voltage 220V DC. In
case of need up to 16 power units can be set together in parallel operation mode, with
possibility of changeover of wrong module during operation without blackout. Output voltage
fuses are placed in rear panel.
The power unit has force cooling which is controlled according to momentary
temperature of the cooler. This solution increases lifetime of ventilator and contributes to low-
noise run of the unit.
Regulation is controlled by processor card ProDrive III equipped DSP processor Texas
Instruments.
Processor control with combination of power electronics elements temperature
measurement allows short-term operation by reducing output current as well during
deterioration of temperature conditions.
The unit can be equipped by 3“ HMI colour LCD panel. The HMI panel can be fit in
switchboard as well.

Installation
Mechanical mounting
The power unit is fit into 3U 19`` rack and is designed for built-in mount into
switchgears. The unit is necessary to mount into factory made support panel or into
corresponding device. The unit is fixed by four screw-bolts M6 going throw front panel
(picture 2). Mounting dimensions including mounting holes dimension are shown on
picture 1.
Picture 2 Mounting
The unit has to be mounted only in horizontal position. Sufficient room for inflow and
outlet of cooling air is necessary – 50mm in front of unit, 100mm at back of unit. The
surrounding temperature must be in range from -25°C to +40°C, otherwise right function can
not be warrant.
Electrical wiring
All connection and signalling points are situated in front panel.

Table 2 Connectors
In case of external HMI panel mounting is necessary to connect port RS232 with the
charger and provide power supply 24V DC for HMI panel. For the power supply connector 4
(OUT 5) can be used, terminals 14 (+) and 16 (-). This possibility has to be set by
manufacturer.
The isolation of the wires plugged into connectors despatch only in needed length,
touchable bare wiring is not allowable
Screw-terminals of connectors 1-5 are to be tightening by torque 0,5Nm, connector 6
by torque 1,5Nm and connector 7 by torque 2Nm.
Earth wire on terminal PE in connector 7 must be plug-in properly.

Battery connection
The inputs wiring resistance can be measured before battery plug-in. For this
measurement, battery supply wiring is unplugged on battery, the wiring is connected (charger
far end) and the charger provide resistance measurement. The measurement is release by
switching input IN2 (function “Start of resistance measurement”). Charger works with the
result of measurement and the output voltage is adjusted which means, charger compensate
resistance of supply wiring.
After measurement the battery can be plug-in, it is necessary to observe the procedure
recommended by producer of batteries.
The function for wiring resistance measurement is optional, not all chargers can
provide it. Before application of this function consult the possibility with manufacturer.
Observe the right battery polarity!
Only battery with nominal voltage the same as nominal output voltage of charger can
be connected.
