STANDARD FEATURES
GENERATOR OPTIONS
GENERAL
● Class H Insulation (rotor and stator)
● Random wound
● 2/3 Pitch minimizes harmonic distortion and
facilitates parallel operation
● 12 Lead standard for differential protection
(12 or 6 Lead standard for 600 V)
● IP23 Housing protects against accidental
contact with hazardous parts and the ingress
of water projection up to 60° spray angle
● ISO9001, CE, CSA, UL compliant
●
●
●
EXCITATION SYSTEM
● Self-excited (AREP for 600 V)
● R448 Automatic Voltage Regulator is
encapsulated for better protection and improved
resistance to vibration. The R448 includes a
load adjustment module to provide engine
relief upon load impact and improves load
acceptance and recovery time.
VOLTAGES
● 415V, 400V, 380V, 220V @ 50 Hz
● 600V, 480V, 440V, 380V, 208V @ 60 Hz

AREP: auxiliary windings provide an isolated
power source to the voltage regulator,
300% short-circuit sustainability, improved
motor starting as well as immunity from
distortion of non-linear loads
Permanent Magnet Excitation: a separate
power excitation system ensures voltage build
up and improves response to transient loads.
The isolated power source protects regulation
from non-linear loads
Premium generator includes:
– Permanent magnet excitation
– R448 Automatic Voltage Regulator
– Coastal Protection (increased insulation
on stator windings)
– 100 Ohm platinum RTD bearing temperature
detector
– PT100 Thermocouple stator winding
temperature detectors
– Space heater
Single and double oversize
Three phase sensing
Quadrature Droop Kit
Digital voltage regulator with KVAR/PF control
RFI Filter
Space heater
