| The Model TU2170 SCR assembly with
digital communications control is used for three phase resistive or infrared
loads that are supervised or controlled by a communications link. With
line currents from 40A–500A up to 500V max, the TU2170 performs time proportioning
control of two phases of a three-phase resistive load (three-wire wye or
delta). A variety of analog inputs are accepted and fast and single cycle
firing modes may be selected. The TU2170 has partial load failure for |
resistive or IR loads and uses V-squared
or VxI feedback. Digital communications are available with Profibus®,
Modbus®, JBUS or EI-Bisynch protocol. Automatic transfer to analog
setpoints occurs in the event of communications failure. Alarms may be
annunciated by LED’s, a relay contact or via the serial link. Units 100A
and up are fan cooled. Fuses are external (above 250A– internal) and ordered
separately. It may be used with the model 260 Diagnostic Unit. |
