- 160 RTCA/DO-160D test firmware.
Includes RCTA-DO160D, section 16, Change #2 and EURO/CAE-14D
AC tests only.
Misc. Options
-L22 Locking Knobs. Shaft lock screws replace knobs to prevent turning of
Voltage and Frequency shuttles.
-LKM Clock and Lock Master. Enables synchronizing outputs of two Lx AC
sources, one acting as master.
This mode supports a frequency range of 45 to 819 Hz on standard
Lx/Ls models. See section 3.9.
-LKS Clock and Lock Auxiliary. See -LKM for details. (see Notes) See section
3.9.
-LNS Line Sync (see Notes)
-EXS External Sync (see Notes)
-RMS Set of 2 Rack mount slides. (Left and Right) Recommended to mount Lx
Chassis in 19 inch instrument cabinet.
Notes: External Trigger input is standard.
Line sync and External sync are mutually exclusive.
External Trigger input and External sync are mutually exclusive.
Units with -LKS (auxiliary) cannot have Line Sync or External Sync.
2.6.1 -HV Option Lx Series - Supplemental Specifications
Specifications for Lx units with -HV voltage range option installed are same as standard Lx unit
except where noted below.
Voltage:
Ranges (L-N):
Low range 0 - 135 Vrms
High range 0 - 270 Vrms
Maximum Current at Full Power
Note: Current, maximum amps per phase available at on low voltage range. 3000Lx and 4500Lx
operate in constant power mode up to currents shown at reduced voltage. See Figure 2-1.
For 9000Lx/2 and 12000Lx/2, currents are 2 x 4500Lx and 6000Lx.
For 13500Lx/3 and 18000Lx/3, currents are 3 x 4500Lx and 6000Lx
Model 3000Lx-HV 4500Lx-HV 6000Lx-HV
Single Phase Mode:
Max. RMS, low Vrange 44.4 A 44.4 A 44.4 A
Three Phase Mode:
Max. RMS, low Vrange
per phase 14.8 A 14.8 A 14.8 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 9000Lx/2-HV and 12000Lx/2-HV, currents are 2 x 4500Lx-HV and 6000Lx-HV.
For 13500Lx/3-HV and 18000Lx/3-HV, currents are 3 x 4500Lx-HV and 6000Lx-HV
Maximum Current at Full Scale Voltage
