RS Series    26 
2.6.2  -XV Option Specifications 
Consult factory for -XV option specifications. 
2.6.3  -HF Option Specifications 
The -HF option extends the maximum available output frequency from 819 Hz to 905 Hz. Some 
restrictions are in effect at this increased output frequency level. 
All other specifications of the RS system remain unchanged if this option is installed except as 
noted in the table below. 
Range:  -HF option:  16 Hz - 905 Hz 
Resolution:  0.01 Hz  < from 16.00 to 81.92 Hz 
0.1 Hz  > from 82.0 to 819.2 Hz 
1 Hz  > from 820 to 905 Hz 
Accuracy:  ± 0.01 % 
±0.25 % for the FC option 
Accuracy:  16 - 100 Hz:  < 1.5°  
100 - 500 Hz:  < 2° 
500 – 819 Hz:  < 4° 
819 – 905 Hz:  < 5° 
High Voltage Range  Maximum voltage at 905 Hz is 290 Vrms 
Maximum frequency at 300 Vrms is 875 Hz 
See Figure 2-7 
Low Voltage Range  Maximum voltage at 905 Hz is 145 Vrms 
Maximum frequency at 150 Vrms is 875 Hz  
See Figure 2-8. 
-HV Voltage Range  Maximum voltage at 905 Hz is 386 Vrms 
Maximum frequency at 400 Vrms is 875 Hz . 
  Note: If the voltage or frequency settings shown here are exceeded for 
any length of time (> 1 sec), the RS may shut down generating an over 
temperature fault to protect itself.
