49 DC MANAGEMENT bluesea.com Part # Description 7615 Automatic Timer Disconnect ATD Automatic Timer Disconnect Select from 4 methods to manage your batteries: Timer Disconnect, Low Voltage Disconnect, Automatic Charging Relay, or Solenoid Timer Disconnect • 12V signal triggers relay to connect battery power to devices • When signal is removed the timer is activated and will disconnect devices after a preset time • Timer ranges from 15 minutes to 4 hours • Optional charge sense can be used instead of 12V signal to reduce wiring • Test mode disconnects devices after 5 seconds to confirm relay and timer are operational Low Voltage Disconnect • Senses low battery voltage and automatically disconnects devices to save power • Adjustable voltage setting at 11.0V, 11.5V, or 12.0V • Low voltage setting can be used in conjunction with timer disconnect. Low voltage will disconnect devices prior to preset time to preserve battery power. Automatic Charging Relay • Automatically combines two battery banks for charging off a single charging source (i.e. alternator) • Isolates batteries when charging source is not present or discharging • Single side sensing design only monitors the voltage of the start battery • Ideal for auxiliary batteries that are AGM or larger than the start battery Solenoid • 12V signal will connect or disconnect relay without any time delay Specifications Nominal Voltage 12V DC Input Voltage Range 9.5–16V Continuous Rating 120A Intermittent Rating: 5 min. 210A (Combine) Amperage Operating Current 175mA (Open) Amperage Operating Current 4mA Cable Size to Meet Current Ratings 1 AWG (50mm²) Maximum Cable Size 1/0 AWG (50mm²) Terminal Stud Size 3/8"-16 (M10) Terminal Stud Torque 140 in-lb (15.82Nm) Time Range 15 Minutes – 4 Hours Regulatory CE marked, Meets ISO 8846 and SAE J1171 external ignition protection requirements IP67-protected against immersion up to 1 meter for 30 minutes 0.97" 24.61mm 2.55" 64.77mm 3.31" 84.14mm 2.56" 65.09mm 4 MOUNTING HOLES FOR #8 OR M4 SCREWS 1.86" 47.12mm 3/8"-16 M10 STUD 0.90" 22.86mm 0.81" 20.45mm 3.89" 98.71mm 1.98" 50.29mm 3.50" 88.96mm cover off
