2Pages

ProTech-4 Series Advanced Electronic, Fully Automatic 4-Step Marine Battery Charger/Power Supply Faster Charging. 2 to 3 times faster than traditional battery chargers. With true 4-step charging technology, each step is electronically controlled for the fastest charge. Auto-Ranging AC Input. Automatically accepts global voltages of 90 VAC to 270 VAC at 45-440 Hz. Conditions and Extends Battery Life. Absorption cycle ensures 100% charge and knocks sulfates off battery plates, extending battery life. Gentle float mode maintains batteries at 100% charge. ProTech 1210, 1220 and 2412 Suggested Uses: Advanced charging reduces water consumption. • Sail or power: Charge 1, 2 or 3* heavy-duty marine battery banks with limited DC usage at the dock. • Typically installed on a 22'-32' vessel with no AC gen set aboard. • 12V engine and/or gen set starting – maintainer/charger/conditioner. • Anywhere 10 or 20 amps at 13+ volts are needed to power equipment with or without a battery in line. • Replaces up to a 60 amp ferro-resonant or conventional charger. Field Selectable. Less Maintenance. Use with lead/acid or gel batteries (AGM factory option). Select length of absorption charge cycle based on size of batteries. At-a-Glance LED Indicators. Provides status of charge cycle. Built-In Safety. Reverse-polarity, ignition and over temperature protection. Easy Installation. May be mounted in any orientation. One-Year Warranty. Includes lifetime repair guarantee. Suggested Uses: • Sail or power: Charges up to three heavy-duty marine battery banks with moderate to heavy DC usage at the dock. • Typically installed on a 22'-50' yacht. • 12V engine and/or gen set starting – maintainer/charger/conditioner. • Live aboard up to 50 amps. Cruising sailors will average up to 50 amps return from 50% discharge (ProTech 1250). • Anywhere 30 to 50 amps at 13+ volts are needed to power equipment with or without a battery in line. • Replaces up to a 150 amp ferro-resonant or conventional charger. • Available with 24V-25 amp output in ProTech 2425. • Also available in 32V and 36V output.
