Note: Accuracy specifications are valid above 100 counts. For multi-chassis configurations, Current
and Power range and accuracy specifications are times the number of chassis.
Note: Frequency measurement specification valid for output > 20 Vrms.
Note: Crest Factor accuracy applies for Irms > 50% of max.
Note: Power factor accuracy applies for PF > 0.5 and VA > 50 % of max.
2.7.4 -AX Option Ls Series - Supplemental Specifications
Specifications for -AX auxiliary output voltage option on the Ls units are listed below. This output
is available on the Phase D and E terminal strip. There is no external sense connection for the
–
AX outputs. Sense is internal only. Specifications apply for programmed frequency range of 360
Hz to 440 Hz.
Parameter Supplemental Specification
Phase D Output
Voltage 26.0 Vrms ± 0.52 V
Load Regulation 1.5 %
Voltage Distortion < 1.0 % THD
Max. Current 3.0 Arms
Frequency range: 360 – 440 Hz, locked to programmed frequency.
If programmed frequency exceeds 819 Hz, -AX outputs will turn off.
Phase error to phase A < 3.0°
Phase E Output
Voltage 5.0 Vrms ± 0.25 V
Load Regulation < 10 %
Max. Current 1.0 Arms
Frequency range: 360 – 440 Hz, locked to programmed frequency.
If programmed frequency exceeds 819 Hz, -AX outputs will turn off.
Phase error to phase A < 3°
2.7.5 -LKM and -LKS Options Ls Series - Supplemental Specifications
The Clock and Lock option enables two independent Ls/Lx power systems to be phase synchronized to
each other. One system (-LKM) acts as the master, the other(s) (-LKS) as auxiliaries. The
–LKS units are
synced to the –LKM unit. Refer to section 3.9 for details on Clock and Lock mode. Note that the maximum
number of auxiliary units (-LKS) per master (-LKM) is one. No T connectors are allowed to increase the
number of auxiliary units as this may cause reflections on the clock and lock signals.
The following supplemental specifications apply when the Ls is configured with the Clock and Lock option.
(-LKM or
–LKS).
