AC regulating - protects against both brownouts & over voltage conditions.
Protects against any power problem other than a blackout.
Will operate through a 3 millisecond (minimum) blackout.
Long life - ferroresonant design - no moving parts.
Ferroresonant design also filters out surges, line harmonics, and RF noise.
Input 120VAC (+10 % to -25 %), 60 Hz
Output 120VAC (+/- 3 %).
Provides circuit isolation.
Noise Isolation (RF) of 120 db common mode, 60 db normal mode.
Spike attenuation: 250:1 minimum.
Sine wave output - total harmonic distortion (THD): 3 %
Units also include a 2nd stage of high frequency filtering on the output - a Hammond Mfg. exclusive.
Operating temperature range of -40 degrees C to +40 degrees C.
Standard 3-wire, grounded plug & receptacle.
Front panel lighted power switch.
Input (primary) connected to an extra long 15 foot, heavy duty 14/3 SJTW cord for extreme temperature ranges.
Integral molded, standard North American plug (NEMA 5-15P).
Output (secondary) connected to a rear mounted, standard North American, grounded receptacle (NEMA 5-15R) -
quantity depends on power capacity of unit (see table below).
Rugged two piece ventilated steel enclosure.
Finished in a grey/beige color, textured powder paint with rubber feet installed.
NOTE 1: Due to the nature of ferroresonant designs - these units do produce audible noise. We have reduced this
NOTE 2: These units provide complete isolation from the source voltage. In other words, the "neutral" output wire has
no connection to ground, this is a UL requirement for this type of device. Therefore plug-in circuit testers
& line "polarity" testing devices will NOT function on the output as it is completely isolated.
North American Mark of Safety: C UL & UL listed (File #E211544).
