Detailed description

Namijenjen za optimalno upravljanje 12V električnim sustavima na moru, uređaj BLUE SEA ATD Automatic Timer Disconnect (referenca 7615) je višenamjenski uređaj koji može obavljati četiri zasebne funkcije: vremensko odspajanje, odspajanje pri niskom naponu, automatsko relejno punjenje (ACR) i jednostavni solenoid. Ta fleksibilnost omogućuje konsolidaciju više funkcija upravljanja baterijom u jednom komponentu, što pojednostavljuje složene instalacije.

Upravljanje napajanjem i zaštita baterija

BLUE SEA ATD 7615-BSS nudi konfigurabilne opcije odspajanja za zaštitu baterija od prekomjernog pražnjenja. U režimu vremenskog odspajanja, uređaj prekida napajanje uređaja nakon unaprijed definirane periode od 15 minuta do 4 sata, nakon što se 12V signal ukloni. Za dodatnu zaštitu, režim odspajanja pri niskom naponu nadzire napon baterije i automatski izolira opterećenja kada napon dosegne podešeni prag (11,0V, 11,5V ili 12,0V), s kašnjenjem od 10 sekundi kako bi se izbjegla neželjena aktiviranja. Ova funkcija se može kombinirati s vremenskim odspajanjem za proaktivno upravljanje.

Funkcije automatskog relejnog punjenja i solenoida

Kao automatski relej za punjenje (ACR), BLUE SEA ATD 7615 automatski spaja dvije baterijske grupe za punjenje iz jednog izvora, a zatim ih izolira tijekom pražnjenja. Dizajn s jednostranim detekcijskim mehanizmom nadzire napon startne baterije, što ga čini prikladnim za AGM pomoćne baterije ili baterije većeg kapaciteta. Uređaj se spaja kada napon dosegne 13,0V tijekom 3 sekunde i odspaja se ako padne ispod 12,75V tijekom 10 sekundi. Konačno, ATD 7615 može djelovati kao jednostavni solenoid, aktivirajući ili deaktivirajući relej trenutačno putem 12V signala, bez kašnjenja.

Robustan i usklađen s morskim standardima

ATD 7615-BSS dizajniran je za zahtjevna morska okruženja, s zaštitom od uranjanja do 1 metra tijekom 30 minuta (IP67). Označen je CE znakom i udovoljava zahtjevima za zaštitu od vanjskog zapaljenja prema ISO 8846 i SAE J1171, osiguravajući povećanu sigurnost. S kapacitetom kontinuirane struje od 120A i povremenom od 210A (5 min), kompatibilan je s kabelima do 1/0 AWG (50mm²) putem M10 vijaka. Podešavanje se vrši putem DIP prekidača, omogućujući preciznu prilagodbu potrebama sustava. Zaštita od prenapona odspaja uređaj ako napon prijeđe 16,0V tijekom 5 sekundi.

« Versatility and protection: the BLUE SEA ATD 7615 for simplified electrical management »

The BLUE SEA ATD 7615 is positioned as an essential component for streamlining electrical installations on board mid-sized sailboats and motorboats. Its unique ability to integrate multiple key energy management functions into a single unit sets it apart from traditional modular solutions. Instead of installing separate automatic charge relays, timed circuit breakers, and low-voltage disconnect devices, the ATD 7615 centralizes these roles, reducing wiring complexity and clutter. This consolidation is particularly beneficial in confined technical spaces.

In terms of practical use, this device is ideal for owners looking to automate protection of their service batteries against deep discharges, or for those who want automatic disconnection of non-essential loads after engine shutdown or a period of inactivity. For example, it can be configured to automatically turn off deck lighting or navigation electronics after a set time, or to isolate the service bank if its voltage drops dangerously low, thereby preserving the starter battery. Its ACR function is relevant for dual-battery systems where the charging source is single and unilateral detection (on the starter battery) is sufficient.

Installation requires an understanding of marine electrical schematics, particularly for cable sizing (up to 1/0 AWG) and the integration of appropriate fuses. It is critical to note that the BLUE SEA ATD is not designed to handle engine starting currents. If used as an ACR, it must not be employed to combine batteries in emergency starting scenarios; a dedicated battery switching system with coupling function is then required. Configuration via DIP switches is simple and intuitive but requires physical access to the unit. The mounting location must be dry and protected to prevent connection corrosion, although its IP67 rating provides significant resistance to moisture.

What are the main functions of the BLUE SEA ATD Automatic Timer Disconnect?

The BLUE SEA ATD Automatic Timer Disconnect is a versatile device that can be configured to perform four main functions:

Timed disconnection: Cuts power to devices after a preset period ranging from 15 minutes to 4 hours once the 12V signal is removed.Low-voltage disconnection: Automatically disconnects devices when battery voltage reaches a configurable low threshold (11.0V, 11.5V, or 12.0V).Automatic Charge Relay (ACR): Automatically combines two battery banks for charging from a single source, then isolates them during discharge.Solenoid: Connects or disconnects a relay without a time delay via a 12V signal.

What is the nominal operating voltage of this device?

The nominal operating voltage of the BLUE SEA ATD Automatic Timer Disconnect is 12V DC.

What is the maximum continuous current that the BLUE SEA ATD can handle?

The BLUE SEA ATD Automatic Timer Disconnect has a nominal continuous current rating of 120A.
