Automatic Timer Disconnect ATD

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
