PT-24-45U Battery Charger

“Smart” marine battery charging technology for 24-volt systems aboard workboats, military vessels, commercial vessels, and recreational craft. This charger interacts with batteries, providing the optimum three-stage charge process for fast recovery and conditioning, maximizing performance, and extending battery life.

A selector switch adjusts output voltage to adapt to gel-cell, flooded lead-acid, or AGM battery types. An optional temperature compensation sensor also adjusts output for ideal voltage based on changes in the batteries’ ambient temperature. All models are housed in a rugged stainless steel case with a durable white powder coat finish, and the internal circuitry is polyurethane coated for maximum corrosion resistance.

Features:

• 24-volt model
• “Smart” circuitry provides three-stage charging – bulk, absorption, float
• Gel-Cell/Flooded Lead-acid/AGM battery type switch selects optimum charge/float voltages
• Multiple isolated output banks; ammeter indicates total output current
• The optional sensor adjusts output voltage based on battery temperature
• Current limiting prevents damage from overloading
• Use as a power supply; can power loads without a battery in line
• Built to last – rugged stainless steel case with a durable white powder coat finish with an optional drip shield and marinized internal circuitry
• Protection: Current Limiting, Thermal Protection, Forced Air Cooling, Drip Shield
• Install in conjunction with PT-MCU for additional control and monitoring
• ABS-type approval for battery charging and power supplies
