JUMO TYA HL301 One-Phase Thyristor Power Controller

The JUMO TYA HL301 is a one-phase, microprocessor-controlled thyristor power controller for precise control of resistive and resistive-inductive loads including transformers, usable in star, delta and open delta connections, with phase angle control and pulse group operation for transformer loads.

It is operated via 4 front buttons and an LED display showing all parameters, configured over USB with setup software, offers U, U-squared, I, I-squared and P control modes for stabilization against mains fluctuations, includes an integrated semiconductor fuse and adjustable soft start, and is rated for 480V/600V/690V operating voltage with current ratings from 300A to 700A+ depending on model.
