  LBD 50KW-1200KW Load Bank Overview

Simplex Load Banks - LBD Bolt-together Load Bank

LBD-Series load banks utilize the radiator air outflow of a generator engine to cool the resistive load elements.

The LBD can be adapted to fit varying site conditions and duct dimensions, making it ideal for after market retrofit. Pictured is a bolt-together LBD. Many options are available to suit individual requirements and simplify installation.

Applications

Reliability exercise and testing of standby generator sets.

Base load leveling to eliminate the deleterious effects of low load operation.

Automatic protection against generator reverse power and motoring of prime mover by power regenerated by inertial loads.
