Stamford 274K 250 kW Generator Head 3 Phase
250 kW Stamford Alternator Model# UCDI274K
Stamford UC is perfect for industrial and marine ac generators in the range 40 to 250kVA. Single or two bearing construction including dynamically balanced rotor and sealed-for-life bearings. Single and three phase voltages available from a 12 wire reconnectable winding. IP23 enclosure protection is provided as standard and PMG is avaialble as an option.
Stamford Newage Automatic Voltage Regulator Model# MX321
The MX321 is a half wave controlled thyristor type automatic voltage regulator (AVR) and forms part of the excitation system for a brushless generator. The AVR has under speed and sensing loss protection features. This model provides closed loop control of the output voltage with load regulation of +/- 1.0%.

120/240 1 Phase
120/240 3 Phase
120/208 3 Phase
277/480 3 Phase
When purchasing a 3 phase (277/480V) generator, you can opt to have it rewired to one of the above options, otherwise, 3 phase generators come standard 277/480V. If you need your 3 phase generator rewired to one of the options above, please let us know when placing your order. Please keep in mind that a 3 phase generator rewired to dedicated single phase 120/240V will lose 1/3 of its power.
