The DEIF INWATT NGS is a precision watt converter designed to measure and transmit active power readings within marine electrical control systems. Operating as a transducer, it accepts current transformer (CT) and voltage transformer (VT) signals from the ship’s main switchboard or generator panels and converts them into a proportional DC current output suitable for integration with power management systems, automation controllers, and monitoring equipment. As a critical element within the Marine Control System category, this unit enables accurate real-time power metering essential for load sharing, power limitation, and system protection aboard commercial and industrial vessels.
Key Features
✓ Measures active power over a range of 0–2376 kW using a 2-wire coupling configuration, with a DC output of 0–200 mA and a maximum load resistance of 750 Ω, enabling direct integration with downstream instrumentation and control panels.
✓ Designed for use with a CT ratio of 5000/5A and a VT ratio of 380V, with auxiliary supply drawn from 380V AC connected to terminals 4–5, making it compatible with standard marine LV switchboard configurations.
✓ Compatible with DEIF power management and control architectures, supporting seamless integration into generator control panels, main switchboards, and vessel-wide power monitoring networks — subject to confirmation of system version and configuration.
✓ Suitable for installation within enclosed electrical panels and switchboard cabinets in machinery control rooms or engine rooms; mounting and environmental rating should be confirmed against vessel-specific drawings and panel specifications.
✓ As a direct replacement or retrofit component, the INWATT NGS converter supports like-for-like substitution in DEIF-based power management installations, minimising reconfiguration requirements during scheduled maintenance or unplanned replacement scenarios.
Marine Applications
✓ Main switchboard power metering on merchant vessels, tankers, and bulk carriers where accurate kW measurement is required for generator load sharing and power management.
✓ Generator control panels aboard offshore support vessels, platform supply vessels (PSVs), and anchor handling tugs requiring real-time active power feedback.
✓ Integration with vessel power management systems (PMS) on cruise ships, RoRo ferries, and passenger vessels where load limitation and blackout prevention are operationally critical.
✓ Retrofit and upgrade projects on aging tonnage where original DEIF instrumentation requires like-for-like replacement to maintain control system integrity and classification compliance.
✓ Newbuild electrical installations on workboats, dredgers, and research vessels incorporating DEIF control and monitoring solutions as part of the vessel’s integrated automation system.
Why Marine Engineers Choose
The DEIF INWATT NGS watt converter is a proven transducer within DEIF’s instrumentation range, valued for its straightforward wiring interface, defined DC output characteristics, and compatibility with DEIF power management architectures. Its clearly specified electrical parameters reduce commissioning uncertainty and support confident integration into existing onboard control infrastructure.
Ideal For
Merchant vessels, offshore support vessels, tankers, bulk carriers, passenger ferries, dredgers, and any commercial or industrial vessel operating DEIF-based power management or generator control systems requiring accurate active power measurement and transmission.
Technical Support & Compliance
Remote troubleshooting, commissioning guidance, retrofit assessment, and integration support are available to assist with the installation or replacement of this unit within existing onboard systems. Compatibility with specific DEIF panels, controllers, or power management system versions is subject to confirmation. To verify suitability, buyers are encouraged to share nameplate photographs, existing part numbers or wiring diagrams, the relevant DEIF system model and software version, vessel name, IMO number, and a clear description of the intended application or scope of supply.
