KDC Series II DC Power Supplies
2.12 -LC Option
The
–LC option has been replaced by the –FT option.
2.13 -FT Option
The
–FT option provides a high current bleeder and reduces the output capacitance of each DC
power module to support faster down programming times. This results in further improved fall
times compared to a standard KDC unit. The output noise and ripple specification is increased by
a factor of 2 when adding the
–FT option.
This option is available only on models with voltage ranges of 30, 40, 60 or 80V. The
–FT option
must be ordered at time of initial order. This option cannot be retrofitted.
The performance specification of KDC power supplies with the
–FT option is the same as a KDC
power supply except as noted below:
The voltage loop compensation is adjusted to reduce overshoot normally associated with the
reduced output capacitance of the power modules. This results in reduced load regulation
performance. An auto level control (ALC) mode is provided on
–FT models to adjust for load
regulation. The ALC mode applies to CV mode of operation only and is automatically disabled
when the DC supply operates in CC or CP modes. The ALC mode can be turned on from the
CONTROL menu.
