INSTRUCTION MANUAL

DEFINITION OF TERMS

• Main Voltage – Rated input voltage range for
the ballast.
• Operating Voltage Range – The acceptable
operating range for input voltage to the
ballast. Deviations from the rated numbers
may result in decreased ballast performance
and additional case generated heat.
• Max Input Power – Maximum possible
wattage draw of the ballast.
• Amperage – Input current or draw.
• Power Factor – A measurement of how
effectively the ballast converts electrical
current to useful power output, in this
case, output to the lamp. Power factor is
measured between 0-1; the closer you get to
1, the more effective the circuit is said to be.
The ballast's power factor is greater than .99.
• Ignitor Voltage – Ballast output during
ignition sequence.
• THD (Total Harmonic Distortion) – A
measurement of all harmonics present in
This product may cause interference to radio equipment and
should not be installed near maritime safety communications
equipment or other critical navigation or communication
This product is warranted to be free from defects in materials and workmanship. The warranty
term is 3 years beginning on the date of purchase. Misuse, abuse, or failure to follow instructions
is not covered under this warranty. This warranty also does not cover any labor associated
with installation or removal of the ballast. We will, at our discretion, repair or replace the
ballast covered under this warranty if it is returned to the original place of purchase. To request
warranty service, please return the ballast, with original sales receipt and packaging, to your
place of purchase. The purchase date is based on your original sales receipt. For more detailed

a circuit. The higher the number, the more
stress is applied to internal parts, the lamp,
and the power grid. Generally, a number
below 10% is considered desirable in an
electronic ballast application.
• CF (Crest Factor) – A measurement of how
"clean" the ballast power output wave is. A
perfectly clean output sine wave would have
a CF of 1.414. Given that some harmonics
must exist in an electrical system, the crest
factor must always be higher than 1.414.
Therefore, the closer the ballast is to a CF of
1.414, the easier it is on the lamp.
• ta (Ambient Temperature) – Maximum rated
ambient temperature for the ballast area.
Excessive ambient temperature can result
in ballast failure, safety shutdown, or lamp
failure.
• tc (Case Temperature) – Maximum
temperature that the case of the ballast
should reach. If the case temperature
exceeds this number, the ballast may be
malfunctioning or the ambient temperature
may exceed the rating.
