GENERAL INFORMATION
Your Phase Three Series Battery Charger represents a new phase in charger design and
performance, employing "smart" switching circuitry which puts batteries through the opti-
mum three-step charge process, adapts for gel-cell or lead-acid batteries, features precise
voltage compensation for varying battery temperature, is rated for continuous duty and is
housed in a rugged stainless steel case.
Following is a brief listing of some of the more important features/options of your Phase
Three Charger. Each is fully detailed later in this manual:
* Three step "smart" charging: bulk, absorption, float
* Gel cell/lead-acid switch selects optimum charge/float voltages based on battery
type
* Multiple output banks charge independently based on demand
* "Universal" input of 90-264V a.c., 50-60 Hz input with no setting of selector switch
required—can be used anywhere in the world
* Current limiting prevents damage from overload
* Load activated cooling fan allows continuous operation at full-rated output
* High charge voltage time-out circuit prevents overcharge during continuous high
amperage demand
* Automatic high temp power reduction — allows continued charger operation in over-
temperature conditions at half of rated output current, avoiding complete shutdown
* Optional temperature compensation sensor (model TCS-12/24) fine tunes output
voltage based on battery temperature
* Optional remote panel (model RP) allows remote monitoring of charger phase status
and manual re-initialization of three stage charge cycle.
* Optional equalization circuit connection.
* Use as a power supply without in-line battery; allows continued use of d.c. powered
electronics (when a.c. is available) in the event that batteries must be taken off-line or
removed.
* Rugged stainless steel case with drip shield
* Carries the CE mark.
