FEATURES
n
Reliable, regulated output voltage when input voltage varies,
even to brownout levels.
n
Extended operation to 65% of nominal when operated at 60% of
full load.
n
Noise rejection—effectively suppressing transient spikes and
surges—120 db common mode and 60 db transverse mode.
n
Rapid response to line and load changes—5% variation in 8m
sec, 10% variation in 16m sec.
n
Hold up time of 3m sec for complete loss of input power.
n
Inherent overload and short circuit protection, without thermo
protectors, fuses or circuit breakers, for immediate recovery
when the overload is removed.
n
Sinusoidal output features, less than 3% harmonic distortion,
improves input wave forms which have total harmonic distortions
of greater than 5%.
n
Available in 250 through 15,000 VA in hardwired models.
n
Handle multiple primary input voltages.
n
Illuminated ON/OFF switch, multiple output receptacles and six
foot input power cord on portable units.
n
UL Listed.

Acme True-Power
®
products consist of speciality designed
ferroresonant transformers. Although ferroresonant transformers
have been an economical solution to power problems for many
years, it took the skills of Acme’s highly regarded engineering
staff to refine it to meet today’s exacting requirements.
For example, typical ferroresonant transformers have an input
limited to 100 -130 V. Acme’s True -Power
®
units have an input
range of +10/-20% around input voltage nominals of 120/208/240
and 480 volts. At 120 volt input, this relates to 95-130 volts.
The typical ferroresonant transformer has limited electrical noise
suppression capability. True-Power
®
power line conditioners
have the following noise attenuation capability:
Common Mode: 120 db
Transverse Mode: 60 db
The typical ferroresonant transformer has an audible hum that
can be objectionable in most offices. Acme’s True-Power
®
power
line conditioners are encapsulated in epoxy to lower sound levels
below ANSI standard C 89.2.
The typical ferroresonant transformer has on output regulation of
± 3% for input line changes only. Acme’s True-Power
®
power line
conditioners have an output regulation of ± 3% for input line and
load changes, making them suitable for operation at any load
condition.
