![]() Typically it would be used to provide the supply voltage to five individual Stick-On modules from a single, possibly remote, source. This unit provides five individually de-coupled and diode isolated outputs from a single DC input. ![]() ![]() 2 Compressor limiter / gain control modules.Also, please tell me if the ACR can be set to charge a Lithium bank without having to modify the alternators on my engines.Categories By brand New products Audio and data connectors Video and RF connectors Power connectors, distribution and batteries Connection panels and stageboxes Fibre optic cables, connectors and interfaces Cable assemblies, patchcords and leads Cables Cabling accessories and tools Bags and cases Racks and enclosures Rack accessories and hardware Lights, clocks, furniture, fittings and equipment supports Drives, memory, media, labelling and sound effects Microphones Radio Microphones Microphone supports, amplifiers, powering and accessories Headphones, headsets, earpieces, amplifiers and wireless systems Hearing protection and noise control Record, replay and radio receivers Audio interfacing Video interfacing, processing, monitoring and camera accessories Audio mixers and processing Amplification Loudspeakers and audio monitoring Test and measurement Communications, conferencing and datacoms Assistive Listening Index By brand Index New products Special offers Clearance list I am guessing my engines and starting batteries don't merit these? Please let me know what ACR you recommend for my situation, and if I need or should have 2. I dont understand what the remote battery switches are in this scenario. I also want to setup ACR's so running one, or the other, or both engines will charge the house bank when their starting batteries are charged appropriately. I want to add a larger Lithium battery house bank and trim the second engines battery bank down to just a starting battery. This means running only one engine, which I frequently do, wont charge the house bank. The manufacture provided a manual switch so either engine can be started off the others starting battery in emergency, but only in isolation. One engine has a dedicated lead acid start battery, and the other a lead acid battery bank that doubles as a start battery and a house bank for the boats 12v system. I have a 44' catamaran sail boat with 2 volvo penta 40HP engines. In the event that a start battery is a bit flat the ACR's can be forced into a manual override combined position to allow starting from all the batteries combined. As soon as the engine is stopped or the charge source goes away the ACR's will separate and each battery will be on its own. Each load has a switch to its respective battery, and the three battery banks are liked together using Automatic Charge Relays (ACR's) So when any engine is running and charging its dedicated start battery the ACR's will combine and send the charge to all the batteries. The switches shown have manual lockouts for servicing. These two requirements are pretty much mutually exclusive on a larger boat unless remote switches are used. Remote battery switches are used so that the switches can be as near the batteries as possible (as required by ABYC) while also being accessible (also per ABYC). The boat has two engines, each with their own starting battery, and a large house battery. This is a greatly simplified drawing that only shows positive wires and omits circuit protection. There are many ways to do a layout for multi-engine boats, here is one simple way to do it using remote switches.
