274K 250 kW Generator Head
PDG Industrial 274K 250 kW brushless alternator with MX341 AVR and PMG excitation, 12-wire reconnectable winding; used in industrial, marine and offshore generator sets.
Description
PDG Industrial 274K 250 kW Generator Head is a brushless synchronous alternator for AC generator set assembly. PDG Industrial alternators cover generator set configurations from 10 to 600 kVA at both 50 Hz and 60 Hz.
Key features
- MX341 automatic voltage regulator (two-phase sensed), part of the brushless excitation system
- Excitation power from a three-phase permanent magnet generator (PMG), isolating the AVR from non-linear loads and reducing radio frequency interference at the generator terminals
- 12-wire reconnectable winding for multiple voltages
- Improved motor starting and short-circuit maintenance
- Over- and under-voltage sensing on the AVR
Configurations
- Standard three-phase 277/480 V
- Can be rewired to 120/240 V single phase, 120/240 V three phase or 120/208 V three phase (dedicated single-phase 120/240 V rewiring loses 1/3 of rated power)
Applications
Industrial, marine, offshore, commercial, construction, rental, combined heat and power, parallel operation, peak shaving, telecommunications, mining, and other standby or continuous duty.
