High quality UV stabilised plastics ensures the switch doesn't become brittle and crack like cheaper imitations. These switches are manufactured by one of the world's largest switch manufactures and are extremely well proven and tested. Automotive applications are similar and also allow users to isolate power to a device or section of the vehicle at the flick of a switch.Īn isolation switch is ideal for ensuring your batteries aren't drained by small downstream loads during periods of idle time and can also be used to shut off power in an emergency situation.Ī good quality battery isolation switch should be manufactured from high quality materials so it lasts and performs under demanding situations. They're popular in the marine industry and allow the onboard batteries to be electrically isolated from the downstream loads. Single and Dual Battery Isolation Switchesīattery isolation switches are good practice to use wherever you plan to run heavy electrical cable from your battery to a device. These switches have high current ratings and are manufactured from high quality UV stabilised materials ensuring they last. Options for single battery and dual battery isolation. We recommend, for the sake of safety and accuracy, consulting with a technician or a mechanic in choosing the appropriate method before making any purchases.High quality battery isolation switches ideal for marine and automotive applications. These will cost more than the other options due to limited market acceptance.Īpplying one of these three concepts to your alternator will bring about different advantages and will inevitably improve the lifespan and quality of your batteries. Zero Drop Isolators:These isolators are useful in addressing the problem of voltage- dropping.Also, the heat levels will most likely rise, and the currents will split. However, because of the presence of diodes, the voltage is more likely to decrease, which consumes more energy and does not charge batteries quite as quickly. Battery Isolators:Currents will flow more swiftly to the battery.

An Automatic Charging Relay allows the current to pass easily from one battery to the next. The relay will open, and the two batteries will be isolated. When the charge is inactive or overloaded, the voltage will drop to around 12.75V DC.

Automatic Charging Relays:Combined voltage and relays that reach over 13V DC will charge two batteries at the same time.

There are a few main styles to choose between: This benefit is useful in the case of one battery failing and having another battery as an emergency back-up. Doing so, keeps the batteries isolated when not charging. Here you can learn about Automatic Charging Relays, Battery Isolators, and Zero Drop Isolators.Īutomatic Charging Relays allow two banks on a vessel's alternator to be charged simultaneously from one unit. Blue Sea Systems Tech Tip: Automatic Charging Relays Explained We do recommend consulting with a mechanic or technician in the process of choosing an ACR and its features.

One relay will be open, while the other will be closed.

Vulnerable products will be shielded by isolated batteries.

Batteries are isolated, and the relay is open.

Open voltage ranging between 12.25 and 12.75 volts.

Combines batteries and closed relays for extended length of time.

No present charge charge input loads will not exceed set limit.

Batteries will share the present charge.

You will then need to carefully consider which preset ACR settings to choose, followed by the product features. The continuous rating will need to reach levels above the highest alternator output rating, and the intermittent rating will need to be above the biggest load for the battery. You will need to take into account the continuous rating and the intermittent rating. When selecting a particular Automatic Charging Relay (ACR), there are many things to consider in order to get the correct system for your application.
