Dimensions of the K65-12B Voltage Regulator (A) 212.75 mm (8.376 inch) (B) 190.50 mm (7.500 inch) (C) 161.95 mm (6.376 inch) (D) 139.70 mm (5.500 inch) (E) 19.05 mm (0.750 inch) (F) 75.18 mm (2.960 inch)Description of Terminals
Note: When the voltage regulator is used with a permanent magnet generator, ensure that the jumpers are removed between the following terminals: 20 - 28, 22 - 30 and 24 - 26. Ensure that the jumper is installed between terminals 28 and "GND".
Table 1
Number of the Terminal    Description    
GND     Ground    
2     Auxiliary input from VAR/PF Controller and/or min/max excitation limiter    
3     Auxiliary input from VAR/PF Controller and/or min/max excitation limiter    
4     This terminal is used in conjunction with terminal 7 for selecting internal voltage adjustment. Place the jumper between terminals 4 and 7 for using internal voltage adjustment. Remote voltage adjustment requires a remote voltage adjust rheostat between terminals 6a and 7.    
5     1 Ampere Current Transformer (CT)    
5a     5 Ampere Current Transformer (CT)    
6     Common for the Current Transformer    
6a     Common connection for selectable features    
7     This terminal is used in conjunction with terminal 4 for selecting external voltage adjustment. Place the jumper between terminals 4 and 7 for using internal voltage adjustment. Remote voltage adjustment requires a remote voltage adjust rheostat between terminals 6a and 7.    
8     Connect terminal 8 to terminal 6a in order to select a 1 V/Hz underfrequency slope.    
9     Connect terminal 9 to terminal 6a in order to select three-phase sensing.    
20     Sensing input on phase C    
22     Sensing input on phase A    
24     Sensing input on phase B    
26     Three-phase power input    
28     Single-phase power input or three-phase power input    
30     Single-phase power input or three-phase power input    
F1     Positive field lead    
F2     Negative field lead    Internal Adjustments
