The Lorain® BD 2000 is a modular DC to DC Battery Disconnect providing disconnection
and overcurrent protection for +24VDC or -48VDC battery strings. Over-current protection
is provided by a user-specified fuse rated from 1000 to 2000 amps. A shunt, included with
the over-current protection device, measures charge and discharge current and can be
monitored by a Lorain® VPS or LVS MCA, Emerson monitoring equipment, or any monitoring system using a 25mV 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 for
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 a
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). Lowvoltage 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.
A removable door permits easy
wiring access during installation
and maintenance
Disconnect assists in compliance
with local codes
