Technical Specifications

Model:TAS‑331DG

Brand:DEIF

System compatibility:Uni‑line series micro‑controller‑based AC power transducer. Receives three‑phase PT voltage and CT current signals,converts active or reactive‑power value into standard DC analogue signal. Suitable for marine and industrial genset,power‑distribution system,output signal connects to PLC,SCADA,indicator and recording equipment.

Function:Programmable power measuring transducer. Measures AC three‑phase voltage and current,calculates active‑power(Watt) or reactive‑power(var). Single configurable analogue DC output,signal options:0‑1mA,0‑5mA,0‑10mA,0‑20mA,0‑1V,0‑5V,0‑10V. Support up to three output slope settings for non‑linear scaling. Parameters configured via DEIF PC tool,no internal potentiometer adjustment required. Built‑in wiring fault self‑check function on power‑on.

Installation:35 mm DIN‑rail mounting or base screw mounting inside switchgear cabinet

Interface:

‑Screw terminal:three‑phase PT voltage input,CT current input

‑Analogue DC output terminals(current / voltage signal)

‑Auxiliary power supply terminals

‑Service communication port for PC configuration

‑Front‑panel LED status indicator

Circuit feature:Micro‑processor sampling architecture,0.5 measuring accuracy class,surge suppression for measuring terminals,galvanic isolation between input,output and auxiliary power,non‑volatile memory stores configuration parameters,free of mechanical adjustment components.

Feature:Marine classification approved. Measuring voltage up to 690V AC;auxiliary power wide range:57‑690V AC or 24‑220V DC. No mechanical potentiometer,long‑term calibration stability. Distinguished from TAS‑311DG(voltage/current/frequency) and TAS‑321DG(bidirectional current).

Built‑in function

TAS‑331DG power transducer samples AC voltage and current and converts active/reactive‑power into standard DC analogue signal. It transmits scaled measuring value to PLC or SCADA system for power monitoring,load‑limiting and data‑recording purpose. Widely used for marine and industrial power‑distribution cabinet spare‑part replacement.

Product Brief

TAS‑331DG belongs to DEIF Uni‑line series spare‑part family,programmable active/reactive‑power transducer. Configuration completed by PC software without local potentiometer. Input wiring and configuration parameters need to be verified before commissioning. Widely applied for power‑equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
