Appendix C. Source Configurations
This appendix explains the configuration of power sources for the F6000
Instrument. Source configuration is set from ProTesT to meet protection
scheme test requirements.
Convertible Voltage/Current Sources
The F6150 has three convertible V/I sources, each rated at 150 VA. These
sources are referred to as convertible V/I sources because the 6810
option allows them to be used as low range current sources. Each
convertible V/I source can be split into two 75 VA sources to yield as
many as six 75 VA sources.
• When in voltage mode, the ranges for the 150 VA sources are
75, 150, and 300 V. The voltage ranges for the 75 VA sources are
75 and 150 V.
• When in current mode, the ranges for the 150 VA sources are
0.5, 1.0, and 2.0 A. The current ranges for the 75 VA sources are
0.5 and 1.0 A.
The convertible sources can be placed in transient current mode to
increase the output power by 30% and the current range by 50% for
1.5 seconds. When in transient current mode, the 150 VA sources supply
195 VA for 1.5 seconds. The 75 VA sources supply 97.5 VA. The current
ranges for the 195 VA sources are 0.75, 1.5, and 3.0 A. The current
ranges for the 97.5 VA sources are 0.75 and 1.5 A.
Current Sources
The F6000 has three current sources, each rated at 150 VA. Each 150 VA
current source can be split in two to yield six 75 VA sources. The current
ranges for the 150 VA sources are 7.5, 15, and 30 A. The current ranges
for the 75 VA sources are 7.5 and 15 A.
The current sources can be placed in transient current mode to increase
the output power by 50% and the current range by 100% for 1.5
seconds. When in transient current mode, the 150 VA sources supply
225 VA for 1.5 seconds; the 75 VA sources supply 112.5 VA. The current
ranges for the 225 VA sources are 15, 30, and 60 A. The current ranges
for the 112.5 VA sources are 15 and 30 A.
