Input Current
Power factor corrected single-phase AC input; unipolar DC input; sinusoidal
current with AC input; continuous DC current with DC input.
Power Factor
> 0.95 at full output load, >0.65 at 20% output load, >0.45 at no load
Efficiency
72%, minimum
Front Panel Indicator LEDs
• OUTPUT: green = output enabled and isolation relay closed
• POWER: green = input AC/DC power applied to module
•
FAULT: red = internal abnormal operating condition detected; output
disabled and isolation relay opened
• BUS: green = internal bus communication established

ONNECTIONS
Parallel Grouping
Three modules can be connected in parallel: any module could be a master;
adjacent modules to the right (when viewed from the front of the unit) of the
master would be slaves; paralleling could be extended between mainframes;
control interface is automatically configured; outputs must be externally
hardwired in parallel.
Paralleling Performance Degradation
Conforms to requirements of individual module. Programming and measurement
accuracy of output current is reduced to 2% of full scale, at 25 °C, +/- 5 °C.
Multi-Phase
Modules are configured as individual AC sources. Their outputs can be
combined and programmed to produce multi-phase configurations, up to six
phases. Delta and wye loads are supported. Modules must be configured as
wye sources with neutrals connected. Delta-connected modules are prohibited.
