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.
Features
Q
Reliable, regulated output voltage when input voltage varies, even to brownout levels.
Q
Extended operation to 65% of nominal when operated at 60% of full load.
Q
Noise rejection—effectively suppressing transient spikes and surges—120 db common mode and 60 db transverse mode.
Q
Rapid response to line and load changes—5% variation in 8m sec, 10% variation in 16m sec.
