3. Application Fields and Case Studies
DEIF LSU-112DG is ideal for:
- Marine: Offshore supply vessel power management
- Industrial: Cement plant captive power plants
- Utilities: Biomass cogeneration facilities
Case Study:
A Caribbean resort installed DEIF LSU-112DG across 4×1.5 MW diesel generators:
- Reduced generator wear by 30% through balanced loading
- Achieved 99.98% uptime during hurricane season grid outages
- Cut synchronization time from 90 seconds to 8 seconds
4. Competitive Comparison
Compared to similar load-sharing units:
- 40% faster fault detection via integrated harmonic distortion analysis
- Supports 3x more generator units in parallel (up to 32 units)
- Unique “Black Start” capability without external power sources
