• LVD: Low Voltage Disconnect Circuit

The Low Voltage Disconnect (LVD) is used to disconnect
electrical loads from Li-ion battery pack when it becomes
discharged. This will prevent damage to the battery due to
over-discharging. LVD is designed as part of low cost
solution for low voltage systems (48V and below), such as
golf carts. A complete low cost solution includes Li-ion battery pack, cell balancers, Li-ion battery charger and LVD circuit.

• Connections:

  - Two inputs: Key Switch and Ground;
  - Two outputs: Non-delayed output and delayed output.

• LVD Product Specifications:

  - One LVD circuit is required per battery pack or application
  - Input voltage (Key Switch) setting / jumper selection: 12V / 24V / 36V / 48V
    (select one)
  - Output voltages (non-delayed and delayed): Equals Input Voltage
  - Disconnect threshold voltages: 11.6V / 23.2V / 34.8V / 46.4V
    (corresponding to pack voltage setting)
  - Power On time delay: 0 second for non-delayed output and 5 seconds for
    delayed output
  - Disconnect time delay: 15 second for non-delayed output and 30 seconds for
    delayed output
  - Max LVD output current: 2.0 A continuous
  - Dimensions: 3 3/16" x 1 3/8" x 7/8"; Weight: 0.9 oz
