PT-24-20U Battery Charge“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, floatGel-cell/Flooded Lead-acid/AGM battery type switch selects optimum charge/float voltagesMultiple isolated output banks; ammeter indicates total output currentThe optional sensor adjusts output voltage based on battery temperatureCurrent limiting prevents damage from overloadingUse as a power supply; can power loads without a battery in lineBuilt to last – rugged stainless steel case with a durable white powder coat finish with an optional drip shield and marinized internal circuitryProtection: Current Limiting, Thermal Protection, Forced Air Cooling, Drip ShieldInstall in conjunction with PT-MCU for additional control and monitoringABS-type approval for battery charging and power suppliesSpecifications:Input VAC (50-60 Hz.): 85 – 135, 170 – 270Input Amps @ Full Load: @ 115 VAC: 6.8, @ 230 VAC: 4.3 Power Factor: .7Max Output Amps: 20Output Banks: 3Battery Capacity (Amp-Hours): 40– 200Operating Temp.
