Power Controllers

TYA-202 3-Phase Power Controller 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, U 2 , I, I 2 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. Three-phase SCR power controller Simple configuration of the device through plain text display Setup program for configuration via USB interface Transmission of the setup data is possible even without voltage supply to the device (USB port supplies power) Network load optimization through dual energy management Burst-firing mode Soft start function with pulse groups Resistance monitoring and limitation for MoSi2 heating elements Teach-in function for the detection of partial load failure Integrated diagnostic systems (e.g. rotating field detection)
