DEIF TCM‑2 Thyristor Control Module

Technical Specifications

Model:TCM‑2

Brand:DEIF

System compatibility:Thyristor‑based soft cut‑in controller for asynchronous generators. Realises soft grid connection via thyristor phase‑angle control. Supports CAN bus communication for upper‑system interaction. Applied for marine and industrial power‑station,works together with DEIF genset protection and control units.

Function:Complete asynchronous generator soft cut‑in control. Directly measures 3‑phase grid voltage up to 690V AC and CT 1A/5A secondary current. Controls thyristor firing angle to implement smooth voltage ramp‑up for asynchronous generator connection.

Built‑in function

TCM‑2 thyristor control module executes soft cut‑in for DEIF asynchronous generator. It controls thyristor firing angle to limit inrush current during generator grid connection,avoids grid disturbance caused by direct switching. Widely used for marine and industrial asynchronous generator cabinet spare‑part replacement.

Product Brief

TCM‑2 belongs to DEIF power‑control‑system spare‑part family,thyristor soft cut‑in controller for asynchronous generator. Thyristor power circuit wiring and input signal polarity must be verified before commissioning. Widely applied for power‑equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
