Product Overview
The DEIF DELOMATIC‑3 LITE is a compact panel‑mount generator control and power‑management unit, simplified variant of the full DELOMATIC‑3 modular system, for single‑unit or small multi‑genset parallel applications. It integrates generator automatic start‑stop, voltage‑frequency monitoring, automatic synchronisation, synch‑check, active/reactive load sharing, full‑set generator electrical protection, alarm handling and event logging in one compact hardware unit. It addresses typical power‑plant pain points including complex multi‑module PMS system high‑cost, limited cabinet‑installation space, manual synchronisation human error, and insufficient local monitoring for backup‑generator fleets. Power‑system commissioning engineers, marine‑power‑technicians and power‑plant‑maintenance teams benefit from this unit. Built‑in LCD HMI supports local parameter viewing, setpoint modification and alarm checking; multi‑protocol communication enables connection with SCADA/DCS upper monitoring systems. It is widely used for new‑build small‑scale power‑house projects and drop‑in spare‑part replacement for existing DELOMATIC‑3 Lite installations.
Application Scenarios
- Marine Vessel Small‑Scale On‑Board Power‑Plants: Executes genset automatic synchronisation, load‑sharing and generator‑protection for ship auxiliary power systems. Meets marine classification‑society environmental‑vibration requirements for vessel power‑room deployments.
- Industrial‑Plant Backup & Cogeneration Generator Control: Controls diesel/gas‑engine driven backup gensets for factories and CHP facilities. Supports island‑mode operation and grid‑parallel running, supervises synchronisation interlock to prevent out‑of‑phase breaker closure.
- Remote‑Site & Off‑Grid Power‑House Control: Applied for off‑grid multi‑generator power‑supply systems. Automatic start‑stop, synchronisation and load‑distribution logic ensures stable power supply without large‑size central‑PMS racks.
- Legacy‑Power‑System Retrofit & Spare‑Part Replacement: Direct‑fit compact‑panel replacement for older DEIF genset‑control hardware. Standard 96‑mm panel‑cutout footprint minimises cabinet‑panel modification work and shortens site‑downtime during controller swap‑out.
