Control power on this unit is rated at 90-300 VDC, 70-265 VAC @ 48-62 Hz. One of the two ground CT inputs is designed for GE power management while the other is for a ground CT. VT inputs on this unit will accommodate VTs in either a delta or wye configuration. The unit comes with a case.
The motor thermal modeling of the SR469-P5-HI-A20 offers RTD biasing, motor cooling time constants, start inhibit and emergency restarts, unbalance biasing, and overload curves.
