Plasmatronics PR1210L Installation Instructions Manual

PR1210L 12 Volt 10 Amp Regulator
FOR SEALED OR GEL LEAD ACID BATTERIES
A simple two stage regulator for charging sealed or gel lead acid batteries from
photovoltaic panels. It uses a rugged power mosfet and switches on the negative side.
INSTALLATION
Mount the regulator by the holes in the terminal
block. In hot or enclosed spaces, allow 1 cm space
behind the regulator. Connect a wire from the
positive battery terminal to the Battery positive
(BAT+) terminal. Connect another wire from the
negative battery terminal to the Battery negative
(BAT-) terminal. Connect a third wire between the
negative side of the solar panel and the Solar
negative (SOL-) terminal. Connect the solar panel
positive to the positive battery terminal (directly to
the battery, not to the BAT+ terminal on the
regulator). We recommend the installation of a
reverse blocking diode in the solar positive wire.
IMPORTANT: The wire from the SOL- terminal
must not be connected to the chassis of motor
vehicles or motorhomes. If you connect the SOL-
wire to chassis, you will bypass the regulator and
you may overcharge your battery.

+ -
This wire must not be connected to
the chassis of motor vehicle/homes.
Doing so will bypass the regulator
and can overcharge the battery.

the regulator directly
to the positive terminal
on the battery.
HOW THE REGULATOR WORKS
The regulator works like an intelligent switch
between the BAT- terminal and the SOL- terminal.
Charge current flows into the battery until the
battery voltage rises to the boost maximum (14.2 V).
The regulator now switches to float mode. The
current is switched off and the battery voltage slowly
falls. When the battery voltage drops below the float
cut in voltage (13.4 V), the current is switched on
again. The charge current continues to flow into the
battery until the voltage rises to the float maximum
(14.0 V). The charge current is then turned off. The
regulator switches the current on and off to keep the
battery voltage between the float maximum voltage
and the float cut in voltage. When the battery has
been discharged enough for it to fall below the boost
cut in voltage (12.5 V), the unit will switch back into
boost mode.
DO NOT Attempt to test the regulator without a
battery connected. This is not a linear regulator.
The PR1210L is ideal for camping, boating,
and other one or two panel solar applications.
It features brass inserts and screws in the
terminal block and is fully enclosed in resin.
The PR1210L is not adjustable.
