The micro-processor controlled three-phase power controller Jumo TYA 202 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 ohmic-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 burst-firing mode, SSR logical operation, fast logical operation, alpha start and soft start.
Available subordinate controls are U, U², 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.
