PARALLELING
This battery charger will parallel with any other LaMarche model A75D/A75DE with the same output
voltage.
LOAD SHARING
A load sharing circuit is provided. When connected two (2) or more A75D/A75DE units are forced to
share the load equally (less than +/- 5%). To load share, connect the unit outputs (must be the same
DC voltage) in parallel and connect the LS terminals together. If the charger is equipped with a Remote
Equalize Terminal, connect the RE terminals together.
CURRENT WALK-IN
Output current will gradually increase after the battery charger is turned on, reducing current surges.
EMERGENCY RESTORATION
The battery charger may be connected to a battery which is heavily discharged and recharge it without
clearing any protective devices.
