The AlphaGuard employs a patented Charge Management

Technology (CMT) to shuttle excess charge current to batteries

requiring a greater charge, and is contained in a small plastic

enclosure that installs directly on top of one the batteries in the

string or in the optional battery integration tray. A short service

cable connects the AlphaGuard to each of the batteries in the

string. Both 36Vdc (3 battery) and 48Vdc (4 battery) versions are

available. One AlphaGuard is required per string.

An AlphaGuard conﬁgured with the optional voltage sense

cabling and interface module (DSM, ESM, EDSM or External

DOCSIS

) allows the AlphaGuard to interface with a status-

monitoring module. Two AlphaGuard modules can be

connected to single interface module. Refer to individual

interface module documentation for additional information.

> Extends battery life

> Spreads charge voltage equally across batteries

> Compensates for battery differences as they age

> Replace single batteries, not the entire string

> Single battery connections for charge

management and status monitoring

> Safe unattended operation designed to CSA

C22.2 No. 107.1 and UL 1778 Standards

> Optional Potted AlphaGuard for

underground battery vault applications
