Detailed description

Namijenjen za automatsko upravljanje sustavima s dvostrukim baterijskim parkovima, automatski prekidač punjenja (ACR) Blue Sea m-Series 7601 osigurava učinkovitu distribuciju energije za 12V DC ili 24V DC instalacije. Ovaj model idealan je za motorne brodove, vozila za rekreaciju i sustave napajanja izvan mreže koji zahtijevaju kapacitet punjenja do 65 ampera kontinuirano i 115 ampera u prekidnom režimu (5 minuta).

Karakteristike i tehničke performanse

m-Series 7601 razlikuje se po sposobnosti automatskog spajanja baterija tijekom punjenja i njihovog izoliranja tijekom pražnjenja ili zaustavljanja, čime se optimizira raspoloživost energije i štiti startna baterija. Zahvaljujući dvostrukoj detekciji, prepoznaje prisutnost opterećenja na jednom ili drugom baterijskom parku. Uključuje funkciju izolacije pri pokretanju (SI) koja štiti osjetljivu elektroničku opremu od padova i vršnih napona tijekom pokretanja motora. U usporedbi s tradicionalnim baterijskim izolatorima s diodama, ACR poput 7601 nude veću učinkovitost, stvarajući manje topline i trošeći minimalnu energiju punjenja.

Sigurnost i ugradnja

Ovaj prekidač je negoriv, u skladu s zahtjevima zaštite od vanjskog paljenja ISO 8846 i SAE J1171, što ga čini sigurnim za ugradnju na brodove s benzinskim motorima. Klasifikacija IP67 jamči zaštitu od privremenog uranjanja do 1 metra tijekom 30 minuta. Pragovi napona za spajanje su 13,6 V DC (30 s) ili 13,0 V DC (2 min) za 12V sustave, te 27,2 V DC (30 s) ili 26,0 V DC (2 min) za 24V sustave. Otvaranje se događa pri 12,75 V DC (30 s) ili 12,35 V DC (10 s) za 12V sustave. Opremljen je stezaljkama s vijcima 1/4"-20 (M6) i prihvaća kabele do veličine 1/0 AWG, s preporučenom veličinom 6 AWG (16 mm²) za nominalne struje. Ugrađena LED indikacija pruža vizualne informacije o stanju ACR-a, uključujući načine punjenja, izolacije, preniskog napona i greške. Uklonjivi izolacijski poklopac i brzi spojnik 1/4" x .032" za uzemljenje uključeni su kako bi se olakšala ugradnja i zaštita stezaljki.

« Technical analysis: Blue Sea m-Series 7601 automatic charging relay »

The Blue Sea m-Series 7601 automatic charging relay (ACR) is a key component for optimizing energy management on vessels equipped with two battery banks, typically a starter battery and a service battery. Its ability to operate on 12V or 24V DC systems with a continuous current of 65A makes it a reliable solution for medium-sized alternators, commonly found on outboard motors or small inboard engines. This model is particularly relevant for recreational boaters seeking fully automated charging without manual intervention.

One of the major advantages of the 7601 is its Start Isolation (SI) function. This feature effectively protects sensitive onboard electronics by temporarily isolating the service circuit from the starter circuit, preventing harmful voltage fluctuations. Installation is relatively straightforward for a marine electrician, requiring positive connections with appropriate fuses, grounding, and the optional SI line connection. It is critical to follow the recommended cable sizes (minimum 6 AWG) and ensure installation in a protected location, although its IP67 certification provides good resistance to marine environments.

Compared to higher-capacity models in the same series (such as the 7610/7611 at 120A or the 7620/7622 at 500A), the 7601 is specifically suited for applications where alternator output does not exceed 65A, offering a balance between performance, compactness, and cost. It does not replace a battery switch for emergency starting but optimizes daily charging. It is therefore ideal for cruising sailboats or small motorboats where simplicity and reliability of charge management are priorities, without the constraints of a more complex or oversized system. It is important to note that this model is not designed to handle engine starter currents.

Frequently Asked Questions

Need help? Contact us

What is an automatic charge relay (ACR) and how does the Blue Sea m-Series 7601 work?

The Blue Sea m-Series 7601 automatic charge relay (ACR) is designed to automatically manage dual-battery bank systems. It combines batteries during charging for efficient power distribution and isolates them during discharge or when stopped, thereby protecting the starter battery and optimizing energy availability.

What are the continuous and intermittent current ratings of this charge relay?

This automatic charge relay has a continuous current rating of 65 amperes. Its intermittent current rating is 115 amperes, maintained for 5 minutes.

Is the Blue Sea m-Series 7601 relay suitable for 12V and 24V systems?

Yes, the Blue Sea m-Series 7601 automatic charge relay is designed to operate with 12V DC or 24V DC electrical systems.

What are the main functions of the m-Series 7601 charge relay?

Main functions include automatic battery combining during charging, battery isolation during discharge, dual charge detection on either battery bank, and a Start Isolation (SI) function to protect sensitive electronic equipment.

How does the m-Series 7601 charge relay ensure the safety of electronic equipment during engine start-up?

The relay includes a Start Isolation (SI) function that protects sensitive electronic equipment from voltage drops and spikes that can occur during engine start-up.

What is the efficiency of the m-Series 7601 charge relay compared to traditional battery isolators?

Compared to traditional diode-based battery isolators, the m-Series 7601 charge relay offers superior efficiency. It generates less heat and consumes minimal charging energy.

Is this relay spark-protected for use on gasoline-powered boats?

Yes, this relay is flame-resistant and compliant with external ignition protection requirements per ISO 8846 and SAE J1171, making it safe for installation on gasoline-powered boats.

What is the water and dust protection rating of this charge relay?

The Blue Sea m-Series 7601 automatic charge relay is rated IP67, ensuring protection against temporary immersion up to 1 meter for 30 minutes.

Where is the best place to install the m-Series 7601 charge relay?

To prevent corrosion of wires and connection terminals, it is recommended to install the relay in a dry and protected location if possible. Avoid mounting it directly above battery banks.

What is the recommended torque for the stud terminals?

The recommended torque for stud terminals is 60 in-lbs (6.8 Nm).

What type of cable and fuse should I use to connect the charge relay?

For a continuous charge capacity of 65 amperes, it is recommended to use a cable with a minimum size of 6 AWG (16mm²) and a 90A-100A fuse. The maximum supported cable size is 1/0 AWG (50mm²).

How to connect the start-isolation line (SI)?

The start-isolation line (SI) must be connected to the terminal or wire running from the ignition switch contactor to the starter solenoid. This connection must be live only during starting and must be made via an inline fuse rated between one and ten amperes.

Can the m-Series 7601 charge relay be used for engine starting currents?

No, the m-Series 7601 charge relay is not designed to handle starting currents. If batteries must be combined for emergency starting, use a battery switching system with a combining/parallel function.

How to connect the positive terminals of battery banks to the relay?

Connect the positive terminal of one battery bank to one of the 1/4"-20 studs, and the positive terminal of the other battery bank to the other 1/4"-20 stud. Both positive connections must be made through appropriately sized circuit protection (fuse).

How to connect the ground (GND) terminal of the relay?

The quick-connect terminal marked GND (ground) must be connected to the DC system ground via a 1 A inline fuse. This prevents fault currents in this wire.

What is the maximum alternator capacity supported by this charge relay?

This automatic charge relay can support alternators up to 65 amperes.

What are the voltage thresholds for the relay to combine batteries in a 12V system?

In a 12V system, the relay will combine the batteries if the voltage at either terminal is above 13.6V DC for 30 seconds or above 13.0V DC for 2 minutes.

At what voltage are the batteries isolated in a 24V system?

In a 24V system, batteries are isolated when the voltage at either terminal drops below 25.5V DC for 30 seconds or below 24.7V DC for 10 seconds.

Does the relay have undervoltage or overvoltage protection?

Yes, the relay includes undervoltage protection (lockout at 9.5V DC for 12V systems and 19V DC for 24V systems) and overvoltage protection (lockout at 16.0V DC for 12V systems).
