Straight Isolation - Constant Voltage - Plug In (CV Series)
Constant Voltage
A.C. Regulator - Plug In
(120 V to 120V)
• 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).

Line Transformer - Selection Guide
Steps To Proper Transformer Selection
1. What power is available (you need to know both voltage & frequency)?
2. Check the operating voltage of your equipment (is it single voltage or multiple?).
3. What line frequency will your equipment run on? Either 50, 60 or dual 50/60 Hz. (remember, a transformer can NOT
change line frequency).
4. Use the chart below to determine your requirements:
Line

Determine if your equipment is Electronic or Electrical:
- Electronic = containing IC chips, transistors or a circuit such as a radio, shavers, electric toothbrush, computer
printers, camcorder battery rechargers etc...(if in doubt, check with the manufacturer or refer to your manual).
- Electrical = Simple heating device, such as irons, hair dryers, electric blankets, curling irons, etc...
Use the chart below to locate correct series & voltage conversion in the catalog series that follow:
Transformer Type
Your Equipment Type
(determined from

chart above)
Step Up
Use Isolation (series 298)
Could use “Auto” (series 170 or 170E)
Step Down
Use Isolation (series 172, 179 or 289) Could use “Auto” (series 175)
Straight Isolation Use Isolation (series 169 or 171)

IMPORTANT NOTES
Isolation Transformers: Used for maximum safety, versatility (can be used on both electrical & electronic equipment)
and isolation from the power source, used to step-up, step-down or for straight isolation. The disadvantage to using
them is weight (about double the "Auto"), more expensive and larger size. This type of transformer is sometimes referred to as "double-wound"
"Auto" Transformers: are non-isolating units and should be used where only a voltage change is required. The advantages to using them are light weight (generally half that of an isolation unit), less expensive and smaller size. The
disadvantage is no isolation from the power source. This type of transformer is sometimes referred to as a "converter".
Adaptors: We strongly recommend that 3-prong "grounded" plugs be used with all of our products. They should be
used only with our "grounded" adaptors. Adaptors do not affect voltages, they are a mechanical device only to match
foreign "pin-outs" of receptacles and/or plugs.
