Definition Of Terms - Hydrofarm Phantom II CMH 315W Instrucciones

Thank you for your purchase of the Phantom CMh ballast (PHBC3151). Supply power for the ballast is
based on typical commercial or residential input. This ballast should be used only with the matching
315W ceramic metal halide lamp to achieve the highest efficiency, safety, luminosity, and proper
operation.
ALWAYS DISCONNECT THE BALLAST'S POWER CORD
WARNINGS
• Use this Phantom CMh ballast indoors only. Position it in an area away from excessive heat or
contact with liquids.
• This ballast does not rely on the luminance enclosure for protection against accidental contact
with live parts.
• Use the Phantom CMh ballast with a maximum lamp cord length of 50 feet.
• Disconnect the ballast from the power supply before performing any maintenance, lamp
changes, or other modifications.
• Opening the ballast will void the warranty.
• Do not use lamps of any type other than the 315W (T12 38 mm PGZX18 base) with this ballast.
Not for use with external ignitors.
• Do not use the Phantom CMh ballast with Hydrofarm's TM01240 240V timer. The TM01240
timer is not designed for use with electronic ballasts and using it may cause the ballast to fail.
• The Phantom CMh ballast is designed to be used with Hydrofarm power cords ONLY. Using it
with other power cords, or modifying the power or lamp cords, will void the warranty.

DEFINITION OF TERMS

• Main Voltage – Rated input voltage for the ballast
• Watts – Input power
• Amps – 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 Phantom's power factor is greater
than .97.
• Working Voltage – 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.
• Ignitor Voltage – Ballast output during ignition sequence
• THD (Total Harmonic Distortion) – A measurement of all harmonics present in 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.
