Lorain BD 2000

Battery Disconnects for +24 VDC or –48 VDC
Battery String Protection

The Lorain BD 2000 is a modular Battery Disconnect providing disconnection and overcurrent protection for +24 VDC or –48 VDC battery strings. Over-current protection is provided by a user-specified fuse rated from 1000 amps to 2000 amps. A shunt, included with the over-current protection device, measures charge and discharge current and can be monitored by a NetSure™ 701, NetSure™ 700, Lorain VPS or LVS MCA, Emerson monitoring equipment, or any monitoring system using a 25 mV shunt input. The disconnect can be wall mounted or 23-in. rack mounted as required. Separate remote and EPO inputs are standard features that allow operation of the disconnect remotely for use in EPO or low-voltage disconnect applications.

The built-in shunt measures charge and discharge current for the batteries. Battery damage is prevented and battery life is increased with the use of a built-in Vortex shunt card and an optional NetSure™ 701, NetSure™ 700, Lorain VPS or LVS with the MCA set up to limit battery recharge current. An EPO switch can be connected to this disconnect to comply with local and national fire codes (NEC). Low-voltage controllers can be interfaced directly to this disconnect to provide protection of the batteries during discharge.

Safety and security features include a cover that can be locked in place during maintenance operations to prevent access to the battery fuses. A door alarm switch provides a set of contacts that will change state whenever the door is opened. Any access or operation of the door can be monitored using this feature. The door latch can also be tool-secured for restricted access.

The Emerson Network Power battery disconnect is ideal for a data center or central office application. For additional specification, engineering or installation information, specify model Lorain BD 2000, specification number 586400200 for disconnect.
