High and Low Voltage Disconnect (HLVD, 2A rate) for 12V/ 24V/36V/ 48V LiFePO4 battery pack (#6088)

The BMS-HLVD is used to help protect lithium batteries from damage due to over discharge and over charge. It is suitable for use with battery system of 12V, 24V, 36V and 48V. Its outputs will drive contactors or relays directly, up to 2A each.

Connections:

• Two inputs: Battery pack postive and negative
• Two outputs: High voltage output and Low voltage output

Product Specifications:

• One BMS-HLVD circuit is required per battery pack or application.
• Input voltage: Jumper selection: 12V / 24V / 36V / 48V (select one).
• Output Voltage:
  
• Non- Delayed Output - When power is applied to the HLVD and voltage is under 3.55V per cell, this output will immediately turn on. When the voltage rises above 3.55V per cell for a period of 3 seconds this output will shut off. Once the output has shut off it will not turn back on until the voltage has dropped to 3.35V per cell.
• Delayed Output - When power is applied to the LVD and voltage is above 3.1V per cell this output will turn on after 5 seconds. When voltage drops below 2.9V per cell for a period of 30 seconds this output will shut off. Once the output has shut off it will not turn back on until the voltage has risen to 3.1V per cell.
• Max output current: upto 2.0 A continuous with 4A surge for 100mS or less
• Dimensions: 85mm(3.3") x 38mm(1.5") x 25mm(1.0")
• Weight: 1.0 oz (30g).
• Note: This unit does not provide individule cell level protection to the battery, suggest to use cell balancer like PCM-BL20CH, BMS-G40BL, PCM-BL200CH, PCM-B01S10-394-1S .
