Features

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 through careful design, but these units are NOT usable in an

office environment.

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).

Indoor use only.
