    Compact Low Voltage Disconnect (LVD) 12 VDC  Battery Guard

    The PW-LVD-35 is compact and designed to fit almost anywhere. Its waterproof construction is ideal for all 12V mobile or base station type battery systems including solar applications. User-selectable settings for low voltage disconnect of: 10.6, 10.8, 11.0, 11.2, 11.4, 11.6, 11.8, 12.0, 12.1, 12.2 VDC. The LVD-35 will automatically reconnect batteries when the voltage reaches 12.8V or higher.

    Installation

    The PW-LVD-35 should be installed in between the 12V battery and the DC load. Typically, the load is a two-way mobile radio, mobile computer, cellular router and other vehicle DC electronics. Standard installation involves installing the PW-LVD-35 in between the battery and the DC feed side of the radio using the supplied ring terminals. When installing, you need to connect (positive and negative DC power IN & positive and negative DC power OUT).

    Rotary Switch Settings

    User-selectable LVD settings can be adjusted to one of the following low voltage disconnect settings (10.6, 10.8, 11.0, 11.2, 11.4, 11.6, 11.8, 12.0, 12.1, 12.2 VDC).

    Emergency Override Switch

    An extra ring terminal position (AUX) is located next to the LED lights. By momentary applying 12V to this terminal (with a user-supplied switch) it will automatically override the LVD disconnect condition and give you an additional 15 minutes of use for emergency operation.

    Over Voltage Protection

    Over Voltage Protection is included in the LVD-35 unit. Should the LVD-35 ever receive a voltage of 16.5 volts or higher, the unit will automatically shut off protecting the electronics connected on the load side of your unit. Once the voltage drops to 15.0 volts or less the PW-LVD-35 will turn back ON.

    Reconnect Voltage: 12.8V or more

    Low Standby Current Draw: 4mA in standby mode, 94 mA normal operation mode

    Selectable LVD Settings: 10.6, 10.8, 11.0, 11.2, 11.4, 11.6, 11.8, 12.0, 12.1, 12.2 VDC

    Connections: +/- Power IN from Battery. +/- Power OUT to electronics (no ignition wire required). Emergency Override Switch Contacts.

    LED Status Indicators:

    • Solid Green LED light = Power passing through – Normal operation

    • Flashing Green LED light = Low Voltage Battery Disconnect Delay (20 seconds)

    • Flashing Red LED light = Timer has expired, the load is OFF

    • Slow Flashing Red LED = LVD condition, the load is Disconnected

    • Solid Red LED light = Overvoltage Condition (16.5V or more)
