Cummins KTA38 Series Diesel Generator Sets
Overview
This Cummins® Power Generation commercial generator set is a fully integrated power generation system, providing optimum performance, reliability, and versatility for stationary standby, prime power, and continuous duty applications.
- Cummins heavy-duty engine – Rugged 4-cycle industrial diesel delivers reliable power, low emissions and fast response to load changes.
- Permanent magnet generator (PMG) – Offers enhanced motor starting and fault clearing short circuit capability.
- Alternator – Several alternator sizes offer selectable motor starting capability with low reactance 2/3 pitch windings; low waveform distortion with non-linear loads, fault clearing short-circuits capability, and class H insulation.
- Cooling system – Standard integral set mounted radiator system, designed and tested for rated ambient temperatures, simplifies facility design requirements for rejected heat.
- Control system – Standard PowerCommand® electronic control provides total system integration including remote start/stop, precise frequency and voltage regulation, alarm and status message display, AmpSentry protection, output metering, auto-shutdown.
- Enclosures – Optional containerized version available.
- Warranty and service – Backed by a comprehensive warranty and worldwide distributor network.
