Phase Sequence Indicator, Model 34, 50 to 400 Hz

Tektronix Service Solutions  |   Mfr# 34   |   Item# DO-26038-11

$1,754.00 USD/EACH


  • Rugged, panel-mount design
This unit provides readout of correct and incorrect phase sequence. Phase 2 is used as the reference phase. Phases 1 and 3 are compared to the reference phase by means of a logic circuit that determines if the phase sequence is correct (1-2-3) or incorrect (3-2-1) and provides a color-coded readout of the phase sequence. It is operable at any frequency between 50 and 400 Hz.
The device is housed in a standard DB-40 switchboard instrument case and requires no connections other than to the three (3) phases being monitored. The meter scale is color-coded into Red and Green sections for easy identification of proper phase sequence. Three (3) lamps located below each phase
number on the face indicate proper operation. The Phase Sequence Indicator conforms to Mil. Spec. MIL-l-16103D Type II.
