Regulation
SolaHD’s CVS power conditioners will hold output voltages
to ±1.0% or less with input variations as great as ±15%
(115V ±15% or 120 V +10%/-20%). Units operated at less
than rated load will maintain approximately ±1% regulation
over a wider input line voltage variation. Output meets NEMA
voltage specifications even when input voltage drops to 65%
of nominal. The output versus input voltage relationship for a
typical CVS is show in Figure A.
Note: MCR line regulations: ±3% for 60 Hz; ±5% for 50 Hz.
The typical performances shown in Figure B indicate that
most of the residual changes take place near the lower
(95 V) and upper (130 V) ends of the input range. It is
possible to improve output regulation if line variations remain
within a restricted range near the center of the nameplate
range (for example, 100-120 V).
Normally, the output voltage will rise as the load is
decreased. Typical percentages for changes in resistive
load from full to zero load as shown below.
Operating Characteristics of the CVS & MCR Series
Except as noted, all characteristics of Sola/HD’s CVS products
also apply to the MCR series.

Power Protection and Conditioning
Input Characteristics
SolaHD power conditioners include a resonant circuit that
is energized whether or not it is serving load. The input
full primary current. As a result, the temperature of the unit
may rise to substantially full-load level, even at light or no
load. Input power factor will average 90-100% at full load,
but may drop to about 75% at half load and 25% at no load.
In any case, the current is always leading. The input no load
watts are about 12.5% of the VA rating.
Frequency
Output voltage varies linearly with a change of frequency of
the input voltage. This change is about 1.5% of the
output voltage for each 1% change in input frequency and in
the same direction as the frequency change.
Power Factor
SolaHD power conditioners regulate any power factor load.
Output voltage is a function of load current and load power
factor (see Figure C). If lower voltage under lagging power
factor is objectionable, correction may be made with capaci-
tors at the load. “Median” value of output voltage will vary
from the nameplate rating if the load has a power
factor other than that for which the transformer was
designed. Load regulation will also be relatively greater as
the inductive load power factor is decreased (see Figure C).
However, the resulting median values of output voltage will
be regulated against supply line changes at any reasonable
load or load power factor.
current at no load or light load may run 50% or more of the
