The SPSD series Solar Regulation
System is an advanced electronic
control unit for solar power supplies
in remote locations. It will prevent
overcharging, reduce electrolyte loss
and stop over discharge. This will
extend battery life and reduce
State of the art technology has been
Reverse polarity protection
Low battery protection
Rugged IP66 sealed case
construction to create a system with
better performance and more
features than any other regulator in
its class. All control levels are fully
adjustable and can even be changed
by remote control. They are flexible
in use, easy to service and are
powering telecommunications in
some of the most remote parts of the
The SPSD series is designed to control the
charging of batteries from photovoltaic panels and
to protect the batteries from excessive discharge.
It is designed for use in remote power supply
systems for telecommunications or monitoring
Charge Control
Two stage boost/float regulation is used. The
regulation voltages are easily adjustable via the
keypad and display. Up to four stage bank switching
can be used which allows taper charging in the
boost mode and low speed switching regulation in
the float mode. The regulator achieves very low
levels of audio and radio frequency emissions and
is well suited to use with telecommunication
equipment in weak signal areas.
Alarms and generator control are provided by
voltage-free relay contacts. An external sensor for
temperature compensation of the voltage settings
can also be installed.
Remote Control
An RS232/ RS485 serial port is provided which
allows remote examination of the performance of
the system and adjustment of the operating
Modular construction allows simple field repair. Two
test programs are built in. The unit can be housed
in a cabinet sealable to IP66 standard. Operating
range is -15 to 60oC. The standard configuration is
positive ground.
Load Control
The optional load switch allows load disconnection
when the battery voltage is too low or too high.
The low and high disconnect voltages are
The Control Computer
A microcontroller with hardware watchdog
protection is used with a 16 x 2 line alphanumeric
LCD and sealed keypad. Set up data is stored in a
non-volatile EEPROM. Battery & Load voltage,

Circuit breakers are provided to protect the batteries
against fault conditions. To guard against lightning,
surge protection has been included.
The SPSD series use a standard control board which can be used with a
variety of switch boards. The range of combinations available is set out
below. All versions can be ordered without load control if required. The
controllers can be supplied as positive or negative ground and have an
English or Chinese language Display.
