The micro-processor controlled single-phase power controller Jumo TYA 201 displays all parameters in a backlighted LCD display and is operated using the 4 keys on the front.
SCR power controllers are employed where larger resistive and inductive loads have to be switched, e.g. in industrial kiln construction and in plastics processing. The SCR power controller comprises two SCRs connected in anti-parallel, the insulated cooling body and the control electronics.
The operating modes are phase-angle, burst-firing mode, half-wave control, SSR logical operation , fast logical operation, alpha start and soft start.
Available subordinate controls are U, U^₂, I, I² and P control.
Use of a subordinate control ensures that fluctuations in the supply voltage do not affect the control loop during the control process.
