250KVA 200KW Alternator – IEP274K
The 250KVA 200KW Alternator – IEP274K is a brushless, three-phase synchronous alternator, rated 250 kVA / 200 kW, built to be coupled to a diesel engine as the power end of a generating set.
About this part
A brushless alternator with an AVR gives a regulated supply with no brushes or slip rings to wear, which is why it is the standard choice for standby and prime-power sets.
Features
- Premium Brushless Design with Advanced AVR Technology
- Class H Insulation for Superior Temperature Management
- IP22 Protection Rating for Enhanced Durability
- Precision-engineered 4-pole Configuration
- 1500 RPM for 50Hz / 1800 RPM for 60Hz Operation
- Outstanding Voltage Regulation (±1.0%)
- Robust Short Circuit Protection
- Exceptional Waveform Quality (TIF<50, THF<2%)
When to replace it
- Building a new generating set
- Replacing an alternator with damaged windings
- Upgrading a set to a different output rating
Before you order
Confirm the engine flywheel and housing (SAE) size and the bearing arrangement before ordering. A single-bearing alternator is carried by the engine flywheel at one end and needs the matching coupling discs.
Match the number stamped on the part you are removing, or the number in your engine or alternator manual, before ordering. Part numbers are shown for reference so the right replacement can be identified.
Questions
What is the difference between kVA and kW?
kVA is the apparent power the alternator can supply; kW is the real power at a 0.8 power factor. A 100 kVA alternator delivers about 80 kW.
What does single bearing mean?
The alternator has one bearing at the non-drive end. The drive end is supported by the engine flywheel through a flexible coupling.
