Phase Three Battery Chargers
The Phase Three series represents a new dimension in charger design and performance, employing "smart" switching circuitry which puts batteries through the optimum 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.
Phase Three Chargers interact with batteries by regulating both voltage and amperage through each phase of the charging process, depending on battery state of charge, temperature, impedance, duration at high rate, system demand and battery type. The result is rapid battery recovery without overcharge, properly maintained and conditioned batteries, adaptability to changing charge conditions and long battery life.
Features
Charge Characteristics
· Three stage 'smart' charging: bulk, absorption, float. · lead-acid/gel-cell selector switch allows user to set optimum charge and float voltages based on battery type. · Temperature compensation automatically fine tunes output voltage based on battery temperature via remote sensor (optional). · Internal terminals for optional equalization timer connection. · High charge rate controlled by timer and current sensing circuit, switching to float rate even if there is a high continuous demand on any battery bank, preventing overcharge. · Charge cycle timer is initialized each time AC power is applied. · Charges battery and powers load simultaneously. · Multi-battery output, charges 3 independent banks based on demand.
Circuit Characteristics
· Conservative circuit design, switching semiconductors selected to withstand over 200% of nominal power level. · Continuous duty rated to 50° C, with automatic high temperature power reduction. · Operates on 115/230 VAC 50-60 Hz. Can be used anywhere in the world. Accepts wide variation on input, produces full output even from an AC generator with a distorted sine wave output. · Fully functional as power supply without battery connected; well regulated stand alone power source if batteries fail. · Low EMI/RFI emission, compatible with on-board electronics. · Multiple units may be wired in parallel for high power systems.
Indicators/Monitors
· Ammeter displays total charge output current. · Power "ON" L.E.D. (PT-70 + PT-24-35 only). · Remote panel indicates output status and allows manual reset of charge phase (optional). · Remote meter panel (optional) digitally displays battery voltage, up to 5 banks.
Protection
· Stainless steel case with optional use drip shield included. · Current limited won't overload when charging dead batteries. · Variable speed thermally controlled fan with dust filter. · Automatic high temperature power reduction above 50° C. · Circuit board polyurethane conformal coated for use in marine/high humidity environments. · Timer limits absorption charge duration, preventing overcharge when under continuous load. (settable from 5 to 13 hours).
