La Marche offers multiple Battery Charger Technologies for stationary applications with special features to accommodate the marine shipboard applications requirements. La Marche’s chargers are used in all different applications in the marine industry; from engine starting to supplying vessel’s Switchgear equipment. MARINE RELATED FEAUTRES • Conformal-Coating for Circuit Boards • Tropicalization Glyptol Dip for Magnetics• ABS Compliance w/Water Tight Connectors and Drip Shield Coast Guard Compliance (USCG) AC/DC Breakers• Blocking Diodes• Ground Detection (To Protect Against DC Leakage Currents, Which Can Induce Hull Erosion Through Electrolysis) • Multiple Communication Protocols, such as Ethernet Web Server, DNP3, MODBUS, SNMP, and IEC 61850 (Connects with Sophisticated Vessel Monitoring/Control Systems)
The La Marche model A41/A41F battery chargers are renowned throughout the industry like the Constavolt because of their reliability and their precise and constant output voltage to charge your batteries. These battery chargers can supply DC power for all ship board accessories while they simultaneously charge and keep your vessel batteries properly maintained. A wide range of A41/A41F Constavolt models are offered from 12 to 130 Volts DC to suit your needs. The Constavolt is a completely automatic, solid state, constant voltage battery charger built to carry continuous and intermittent loads up to 80% of its maximum rated output capacity. Agency approvals and accessories are available with these models: • U.L. 1236 Listed • USCG (United States Coast Guard) Accessories include a drip shield, On/Off switch & water tight connectors
The La Marche A46/A46F battery charger is specially designed for maintaining and recharging starting batteries of engine generator sets. The controlled magnetic amplifier technology provides the highest reliability that is necessary for the continued operation of the emergency standby equipment and eliminates most starting problems by maintaining batteries at a proper charge, ensuring optimum performance and maximum life. Agency approvals and accessories are available with these models: • American Bureau of Shipping (ABS) • USCG (United States Coast Guard) • UL 1564 Listed and C-UL Listed
MSM La Marche Marine Battery Charger Model uses High Frequency charging technology developed specifically for marine applications. The MSM Charger utilizes both Utility Power and Solar Power in charging up to three independent batteries simultaneously. This Charger series incorporates Power Factor Correction Circuitry to achieve high efficiency and a wide input range. Maximize your battery life with this intelligent charger as this filtered output unit is designed and built to charge VRLA (Gel-Cell, AGM), Flooded Lead Acid and Nickel Cadmium batteries. The MSM is equipped with an LCD display showing DC Volts, DC Amps, and three status LEDs. Integrated Battery Charge Divider/Isolator provide connections for charging up multiple batteries simultaneously. The MSM model is built in a robust, non-corrosive enclosure that addresses the harsh marine environments.
Solar Charge Controller
The La Marche Solar Charge Controller is available in two models, the SCM (Solar Charge Controller – MPPT Technology) and SCP (Solar Charge Controller – PWM Technology). Both models regulate the voltage and current from the solar modules to properly charge the battery and supply the load. In order to maximize the power that can be extracted from the solar modules, the SCM Controller utilizes Maximum Power Point Tracking (MPPT) algorithm. For a simplified version, the SCP controller regulates the charging power using Pulse Width Modulation (PWM). The Solar Charge Controller is available in 10A and 20A versions with 12/24V auto-select output. Both controller models feature built-in protection for solar modules, batteries and load connections. Additional features include Low Voltage Load Disconnect, Status LEDs, USB connection for diagnostic parameters and an extra set of output terminals for additional loads.
USC Ultra Series Charger
The La Marche Ultra Series Charger is a High Frequency Switch Mode charger specifically designed to charge various types of chemistries, such as Lead Acid, Nickel Cadmium and Ultra Capacitors.The case is specifically designed with 16 Ga anodized aluminum for maximum strength against corrosion, while its weight gives the ability to the user for easy handling and installation, without the necessity of a second person. Case is equipped with knockouts, for optional cable entry, either from the sides or the bottom. Removable cover, located on the front, gives access to the customer connections, temperature probe, as well as, the alarm terminals.
Isolation Transformer (ITSM)
The La Marche Marine Isolation Transformer features a Ground (Faraday) Shield between the power windings. This ground shield, when connected to the shore ground, provides protection against capacitive coupling between the shore power and the boat’s electrical systems. This protects the boat electrical equipment against shore power issues, common mode voltage spikes, and the transfer of harmful energy between both systems.
Alarm Box (EAB)
La Marche Alarm Box is a simple compact solution to monitorDC system remotely. The Alarm Box monitors the DC bus for high and low voltagelevels and is adjustable based on battery type and user preference. Positiveand Negative Ground Detection alarms provide safety warnings for your personnelbefore working on the equipment. These alarms are critical, as most of the DCsystems are used in critical applications.
