The DEIF TAS-331DG is a selectable AC transducer designed for precise active power measurement within marine power management and control systems. Operating over a wide measurement range of -150 to 1500kW with a standard 4–20mA analogue output, it converts three-wire three-phase AC electrical signals into stable, scalable signals suitable for integration with power management panels, automation controllers, and monitoring systems aboard commercial vessels. As a core component within the Marine Control System category, the TAS-331DG plays a critical role in ensuring accurate load monitoring, generator control, and power distribution oversight — all of which are essential for safe and efficient vessel operation.
Key Features
✓ Selectable AC transducer measuring active power across a range of -150 to 1500kW, providing reliable bidirectional power monitoring for marine electrical systems.
✓ Configured for 3W3 (three-wire, three-phase) coupling with a VT ratio of 460/115V and a CT ratio of 2000/5A, matched to typical shipboard medium-voltage distribution arrangements — exact compatibility subject to confirmation against vessel switchboard specifications.
✓ Delivers a 4–20mA analogue output with a maximum load impedance of less than 500Ω, making it compatible with a wide range of DEIF power management units, PLCs, and third-party automation controllers that accept standard current loop signals.
✓ Suitable for installation within enclosed switchboard panels and power management enclosures in the engine room or control room; specific ingress protection rating and mounting configuration should be confirmed against original installation drawings.
✓ Replacing or upgrading an existing TAS-331DG requires verification of the VT and CT ratios, coupling type, and output range against the installed system configuration to ensure seamless drop-in compatibility.
Marine Applications
✓ Active power monitoring on main switchboards and generator control panels aboard merchant cargo vessels, tankers, and bulk carriers.
✓ Integration with DEIF power management systems for automatic load sharing, load shedding, and generator synchronisation on offshore support vessels and platform supply vessels.
✓ Power measurement and feedback signal generation within engine room automation systems on cruise ships, ferries, and ro-ro vessels.
✓ Retrofit and upgrade applications where existing analogue transducers require replacement to restore accurate power metering in ageing vessel electrical systems.
✓ Auxiliary power monitoring on naval auxiliaries, dredgers, and heavy-lift vessels where precise electrical load data is required for operational safety and efficiency reporting.
Why Marine Engineers Choose
The DEIF TAS-331DG is a well-regarded component within DEIF’s instrumentation portfolio, valued for its wide measurement range, standard analogue output, and adaptability to the voltage and current transformer ratios commonly found in shipboard power systems. Its selectable configuration makes it a practical choice for both original equipment installations and replacement scenarios where maintaining signal integrity across the power management chain is critical.
Ideal For
Merchant cargo vessels, tankers, bulk carriers, offshore support vessels, platform supply vessels, ferries, cruise ships, ro-ro vessels, dredgers, and any commercial or industrial marine vessel requiring accurate AC power transduction within a DEIF or compatible power management and control system.
Technical Support & Compliance
Remote technical guidance is available to assist with configuration verification, signal loop testing, and integration into existing power management systems. Onboard commissioning support, transducer calibration, and retrofit assessment can be arranged subject to location and scheduling. To confirm compatibility and avoid misapplication, buyers are encouraged to share nameplate photographs, the original part number or order reference, VT and CT ratio data from the installed system, switchboard drawings or single-line diagrams, the DEIF panel or controller model and software version, and vessel name or IMO number where applicable. All compatibility assessments are subject to confirmation based on the information provided.
