Unit Description, Features & Options
General Description
Thermo King clip-on generator sets are
self-contained fully-automatic, diesel powered
units. The generator sets supply 230 or 460 Vac
electrical power for container refrigeration units.
Enclosed within the unit frame are the engine,
dual voltage alternator, generator battery
compartment, battery charging regulator and
control panel.
An exclusive TK486V (EPA Tier 2) direct
injection diesel engine drives a brushless
generator to produce 15 KW of output power at
49 C (120 F) ambient temperature. A
weatherproof box fastened inside the unit contains
the unit controls.
Each unit features a welded, heavy-gauge steel
frame with special sea-going finish; non-corrosive
fittings, all stainless steel external hardware,
copper tube aluminum fin radiator, and poly-vinyl
coating on the engine and generator.
Fuel tanks are provided as an integral part of each
unit. Fuel capacities are: 473 liter (125 gal.) on
SGCO clip-on models.
The alternator is a brushless, rotating field ac
generator. A rectified exciter armature output
provides dc power for the field. The exciter field
obtains its power from the full wave rectified
output of the main generator. The alternator
supplies 230 or 460 Vac, 3 phase, 4 wire, 60 Hz
power at 1800 RPM.
This equipment develops normal output voltages
(below 600 volts) whenever the engine is running.
All output voltages normally reach 460 volts.
Under malfunction conditions, 575 volts may be
produced. Any electric potential more than 50
volts is hazardous. Exercise caution and discretion
in the operation and maintenance of the
equipment.
