The DEIF TAS-331DG is a factory-configured, selectable AC transducer designed for the precise measurement of active power (kW) or reactive power (kVAR) in three-wire, three-phase electrical systems. Operating to Class 0.5 accuracy and accepting auxiliary supply voltages from 57 to 690 V AC or 24 to 220 V DC, this transducer converts electrical power signals into a calibrated analogue voltage output of -10 to +10 V, making it well suited for integration into marine control and power management systems. Onboard vessels, accurate power measurement is fundamental to generator load sharing, power distribution monitoring, and energy management — all of which are critical to safe and efficient propulsion and hotel load operations. As a Marine Control System component, the TAS-331DG plays a key role in ensuring that shipboard electrical plant data is reliably captured and processed.
Key Features
✓ Factory-configured for active power or reactive power measurement with Class 0.5 accuracy, supporting a measurement range of -893.75 to +893.75 kW across a 3W3 three-phase coupling arrangement.
✓ Wide auxiliary supply compatibility spanning 57 to 690 V AC and 24 to 220 V DC, with measuring voltage support up to 690 V, making it adaptable to varying shipboard electrical system voltages — subject to confirmation of specific vessel configuration.
✓ Analogue output of -10 to +10 V with a load requirement of greater than 500 ohms, configurable across up to three output slopes via PC tool or pre-configuration, offering flexibility for integration with DEIF power management panels and compatible third-party control systems.
✓ Configured for a VT ratio of 440 V (L-L) and a CT ratio of 1500 A/5 A as per the supplied specification; alternative VT/CT ratios and output configurations may be available — compatibility with existing instrument transformers and control panels should be confirmed prior to installation.
✓ Suitable for installation in switchboard panels, generator control cabinets, and power management enclosures in dry, protected areas of the vessel; intended as a direct replacement or retrofit component within DEIF-based or compatible marine power monitoring systems.
Marine Applications
✓ Generator load sharing and power distribution monitoring on merchant vessels, offshore support vessels, and platform supply vessels operating multi-generator electrical plants.
✓ Integration into DEIF power management and automatic generator control systems for real-time active and reactive power measurement across main and emergency switchboards.
✓ Retrofit or upgrade of existing AC transducer installations on tankers, bulk carriers, and RoPax ferries where improved measurement accuracy or digital configurability is required.
✓ Power quality monitoring and energy management applications on cruise ships, offshore drilling units, and naval auxiliaries where precise kW and kVAR data feeds into vessel energy optimisation systems.
✓ Instrumentation support for shore power (cold ironing) and hybrid propulsion monitoring applications where accurate power flow measurement across multiple sources is operationally essential.
Why Marine Engineers Choose
Marine engineers and electrical officers specify the DEIF TAS-331DG for its proven Class 0.5 accuracy, wide voltage compatibility, and straightforward PC-based configuration, which reduces commissioning time and allows the unit to be precisely matched to the onboard VT/CT ratios and control system output requirements without the need for custom hardware.
Ideal For
Merchant vessels, offshore support vessels, platform supply vessels, tankers, bulk carriers, RoPax ferries, cruise ships, offshore drilling units, and any vessel type operating DEIF or compatible power management and generator control systems requiring reliable AC power transducer instrumentation.
Technical Support & Compliance
Technical assistance is available to support remote troubleshooting, configuration guidance, onboard commissioning, and integration of this transducer into existing marine control and power management systems. Retrofit and upgrade support can be provided to assist with replacing legacy transducer types — subject to confirmation of system compatibility. To confirm suitability for your specific installation, buyers are encouraged to share nameplate photographs, the original part number or order code, VT and CT ratios in use, existing control panel model and software version, any relevant wiring diagrams or system drawings, and vessel name and IMO number where applicable. All compatibility and configuration claims are subject to confirmation based on the information provided.
