Description
The H6635/42276 Portable Alternator provides instant
electric power for lighting, heaters and other electrical
equipment. It is driven by a hydraulic gear motor and is
able to operate from hydraulic systems with flow rates
from 30-45 l/min (8-12 gpm). The alternator, a 60-cycle,
single-phase unit, is capable of delivering up to 3500
watts of electrical power through its 120 and 240 volt AC
outlets.
The 120 volt duplex receptacle is split so that 15 amps
of current may be drawn from either half of the receptacle.
These outlets may be used along with the 240 volt
receptacle provided the alternator is not overloaded.
A maximum of 14.6 amps may be drawn from the 240
volt receptacle provided it is the only receptacle used.
When using the unit, current must be limited to the
ratings on the nameplates of the equipment being
used. If the 240 volt receptacle is used along with the
120 volt receptacles, the total load drawn must not
exceed the equipment’s nameplate ratings.
