LSU220A : Load Support Unit
Operators Manual
2 DESCRIPTION
The LSU220A is a general purpose load support unit designed to act as a permanent power
supply to maintain backup battery systems whilst alternative sources of power are either
impractical or unavailable, such as running diesel engines during maintenance programs.
The LSU220A can support both 12V and 24V systems by simple manual voltage adjustment,
with a current capacity of up to 220A amperes.
7 segment display continuously shows both set voltage and current draw.
Voltage output can be trimmed in small steps during operation to offset cable drops and/or
variations in demand which can create excessive demand on the backup batteries.
Output is simply enabled or disabled by run and stop buttons.
Internal variable speed fans are employed to ensure the LSU220A operates at a reasonable
temperature.
The LSU220A is designed to operate from a standard star connected 415V three phase supply
in a L1 + L2 + L3 + N + E configuration.
The LSU220A has a simple user calibration procedure to ensure the displays show accurate
readings.
