Recommended Installation Instructions

DO NOT CONNECT OR DISCONNECT WIRING IN A HAZARDOUS ENVIRONMENT!

1. Securely mount the 1950-136 5A SLA Solar Battery Charge Controller in an
approved enclosure near the battery to be charged. The charge controller may
be bolted to a back plate using the available mounting flanges, or an approved
adhesive may be used to attach the charge controller to an available flat surface.

SOLAR BATTERY CHARGE CONTROLLER

Part No. 1950-136

CSA Certi ed

Class 1 Div 2 Hazardous Locations

2. Run wire from the charge controller’s terminals to the battery. 18 gauge wire is
recommended if the solar panel provides 1 Amp or less charging current, or 14 gauge
wire if it provides more than 1 Amp of charging current. Strip the wire back 3 mm
(~1/8”) and insert the bare portion into the terminal, then tighten the screw until it
crimps down securely on the wire. An approved in-line fuse holder should be wired
in series between +BAT terminal of the charge controller and the positive terminal of
the battery. A 5 Amp fast-blow style fuse is recommended for circuit protection. If
the battery terminals are connected backwards the LED on the charge controller will
light indicating reversed wiring, and the charge controller will not charge the battery.

3. Run cable from the solar panel through the bottom of the enclosure or provided cable
entrance to the +IN and GND terminals on the charge controller. Strip the wire back 3 mm
(~1/8”) and insert the bare portion into the terminal, then tighten the screw until it crimps
down securely on the wire. If the battery enclosure is located in a potentially hazardous area,
ensure use of conduit or approved cable, and properly seal all wiring entrances as required.

JUMPER SETTINGS

To gain access to the jumpers, remove the plug-in connectors and the four screws from the corners of
the cover. There is one jumper to select between 12 and 6V.

12V / 6V

There are three sets of jumpers across the bottom. The leftmost set has three pins. Place the jumper
accross the middle and left pin for 12 Volt operation (this is the factory default). Place the jumper
across the middle and right pin for 6 Volt operation. If this jumper is not installed, the charger
defaults to 6 Volt operation.

Throughout this document “paired” voltage levels are used to describe operating parameters. The
 rst number will represent 12V operation. The second number in parentheses ( ) will represent 6V
operation.

FAST CHARGE

The middle set of jumpers is used to enable the fast charge mode. With this jumper in place the
charger will immediately go into the fast charge mode when the battery voltage falls below 12.8V
(6.4V). The charger will fast charge the battery to 14.7V (7.4V) and enter a compensation mode.
When the charging current falls o indicating the battery has been charged, the fast charge turns o .

This jumper in place is the factory default setting.

Float Mode Voltage ~14.1V (7.0V)
Self Consumption 400 uA (not charging), 2mA (charging)
Temperature Compensation -3.3mV / deg C / Cell
Operating Temperature -40 to 60 deg C
Environmental Encapsulated
Pluggable Connectors 12 AWG Max Wire Size

FLOAT CHARGE

The right set of jumpers is used to enable the  oat charge mode. With this jumper in place the
charger will maintain a battery voltage 14.1V (7.0V). This will hold the battery in a fully charged state.
The charge controller enters this state automatically whenever the Fast mode shuts o . This jumper
in place is the factory default setting.

At least one of the jumpers for Fast/Float must be in place for the charger to operate. Normally,
both jumpers should be left in place to enable the charge controller to select the best charging
method for the battery.

TEMPERATURE COMPENSATION

The charge controller has built-in temperature compensation. The charger should be mounted in the
battery box near the battery for optimal compensation.

REVERSE BATTERY INDICATOR

If the battery is wired with the positive and negative terminals reversed, the red Reverse Battery LED
will light. The controller is internally protected from damage from reverse wiring on both the solar
and battery terminals, but must be wired correctly to charge the battery.

The graph above shows a charging cycle typically found when an SLA battery has discharged overnight.
The red line (upper) indicates the battery terminal voltage and the green line (lower) indicates the charging
current supplied to the battery.

With the battery below approximately 2.13 Volts per cell, the charge controller enters the fast charge mode.
The charger will supply the maximum current possible to the battery until the terminal voltage reaches 2.45
Volts per cell. As the battery approaches a fully charged state, the charger enters a compensation charging
mode and the charging current will taper o . When the current reaches a steady-state value, the controller
will switch to the  oat charge mode. The controller will both supply current to the load and maintain the

battery at approximately 2.35 Volts per cell as long as charging power is available.

NOTE: Due to the low noise linear charge method used by this product, it is possible to overheat
a unit by using a power supply or solar panel with a working voltage much higher than the battery
voltage. Maintain power dissipation in the charger below 4 Watts by using a panel or power supply
with an appropriate working voltage, i.e., ~ 8-9V for 6 Volt batteries and 16-17V for 12 Volt batteries.
