THE BATTERY & OUTPUT VOLTAGE ASSOCIATED WITH THESE CHARGERS PRESENTS
AN ELECTRIC SHOCK HAZARD.. THE INSTALLER/USER MUST BE FAMILIAR WITH THE
REQUIREMENTS OF THE LOW VOLTAGE DIRECTIVE (AS ENACTED IN NATIONAL LAW)
BEFORE PROCEEDING WITH INSTALLATION & USE OF THIS EQUIPMENT.
Overview
The Universal Power Charger (UPC) family is one of the most compact battery chargers available. It
is supplied in three frame sizes, each covering a range of power outputs: UPC800, UPC1600,
UPC3200.
Each series shares the same control system and operates in the same way. They differ in their
method of mounting and the size of the power stage.
INSTALLATION
Choose a location where the unit will not be subjected to water spray, dust, or insect ingress.
Locations subjected to high temperature or vibration must be avoided if performance and reliability
are not to be impaired.
The power system may be mounted in any orientation, but ensure that there is sufficient clearance
around the unit to allow air to enter and leave without undue restriction (25 to 30mm clearance is
sufficient). Any possibility of the air vents becoming accidentally obstructed should be prevented.
Ideally, the unit should be located in the same area as the load equipment or battery in order to
minimise voltage drop in the DC output leads, and also to ensure that the Power Charger
temperature compensating charge system samples air with the same temperature as the batteries. If
a similar operating temperature environment cannot be provided, then a remote temperature/voltage
sensor is available as an option.
Mounting
800 series
Integral flanges are provided for ease of mounting in situations where the unit needs to be
secured to prevent movement, such as in vehicles. Ideally, the mounting should make electrical
contact with the vehicle bodywork.
1600 Series
Mounting is by means of either a bridging bracket mounted over the rubber shock absorber ends,
or via flanges on the end brackets
.
3200 Series
The charger can be used positioned horizontally on a table or a shelf, hung on a wall using the
free supplied bracket, or as a built in charger in the vehicle. When it is built into a vehicle it will
usually need to be attached using anti-vibration mounts. The charger can be either directly
connected to the battery, or with suitably sized DC connectors.
