2.7.1 -HV Option Ls Series - Supplemental Specifications
Specifications for Ls units with -HV voltage range option installed are same as standard Ls unit
except where noted below.
Voltage:
Ranges (L-N):
Low range 0 - 156 Vrms
High range 0 - 312 Vrms
Maximum Current at Full Power
Note: Current, maximum amps per phase available at on low voltage range. 3000Ls and 4500Ls
operate in constant power mode up to currents shown at reduced voltage. See Figure 2-1.
For 9000Ls/2 and 12000Ls/2, currents are 2 x 4500Ls and 6000Ls.
For 13500Ls/3 and 18000Ls/3, currents are 3 x 4500Ls and 6000Ls
Model 3000Ls-HV 4500Ls-HV 6000Ls-HV
Single Phase Mode:
Max. RMS, low Vrange 38.4 A 38.4 A 38.4 A
Three Phase Mode:
Max. RMS, low Vrange
per phase 12.8 A 12.8 A 12.8 A
Note: Current derates linearly from 50% of voltage range to 20% of specified current at 10% of
voltage range.
Current in High voltage range is reduced by a factor of 2.
Note: For 9000Ls/2-HV and 12000Ls/2-HV, currents are 2 x 4500Ls-HV and 6000Ls-HV.
For 13500Ls/3-HV and 18000Ls/3-HV, currents are 3 x 4500Ls-HV and 6000Ls-HV
Maximum Current at Full Scale Voltage
