Three-phase phase angle controller TYA HL303

Overview
The JUMO TYA HL303 is a three-phase thyristor controller designed for controlling non-linear loads with load currents from 300 to 800 A. Its compact footprint and top-bottom wiring make it suitable for space-constrained control cabinets. Integrated data logging and an oscilloscope support process monitoring and troubleshooting, while the setup program with wizard simplifies commissioning.

Highlights

• Optional load management for up to 24 zones
• Versatile communication protocols (USB, Modbus RTU, optional PROFINET, EtherNet/IP, Modbus TCP, EtherCAT)
• Suitable for all load types (resistive, inductive, non-linear)

Customer benefits at a glance

• High flexibility: multiple control modes (U, I, P, U², I²) and many fieldbus options
• Reduced SKUs: one device covers a wide range of applications
• Energy savings through optional load management and optimized control
• Improved process reliability via data logging and integrated oscilloscope
• Space-saving installation due to compact design and efficient wiring
