125KVA 100KW Alternator – IEP274ES
IEP274ES is a generator alternator, rated 125 kVA / 100 kW for building or repowering a diesel generating set.
About this part
The alternator converts the engine's mechanical power into electricity. Its rating has to match the engine: an undersized alternator overheats, an oversized one adds cost without adding usable power.
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
Rate the alternator for the engine's output at your site conditions; altitude and high ambient temperature both reduce what it can deliver.
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.
