18-120-400HZ
The Model 18 continuously monitors 3-phase power lines for abnormal conditions. When properly adjusted, the Model 18 monitor will detect phase loss on a loaded motor even when regenerated voltage is present.This device consists of a microcontroller with a voltage and phase-angle sensing circuit, driving an electromechanical relay. When correct voltage and phase rotation are applied, the internal relay will energize. A fault condition will de-energize the relay. When the fault is corrected, the monitor will automatically reset. An adjustable restart delay prevents short cycling in compressor applications and an adjustable trip delay prevents nuisance tripping during power fluctuations.
The Model 18 does not require a neutral connection and can be used with Wye or Delta systems. Voltage ranges are sufficiently wide to allow for proper adjustment to existing conditions. Both FAULT and NORM condition indicators are provided to aid in adjustment and system trouble-shooting. The Model 18 is UL Recognized in the U.S. and Canada and is available with optional gold flashed silver contacts for low current applications.

208D-208/240V
The Model 208A & 208D Line Voltage & Phase Sequence Detectors allows quick and easy determination of phase sequence (either ABC or CBA). Available in 50/60 Hz and 400 Hz versions, this unit can also show that all phases are present, or if one or more phases are lost, it indicates which of the phases are missing. To use, connect the Detector to any 3-phase circuit, Wye or Delta. In proper phase sequence, and with all phases present, the ABC lamp, and the three line voltage lamps will illuminate. An open phase condition will illuminate both rotation lamps and only two line voltage lamps. See the Condition Chart. -
25
Model 25 True RMS 3-Phase Monitor has a display that shows the voltage with an accuracy of +/- 0.5%. The display is updated every second and re-initialized every 30 seconds. Model 25 has a rotary encoder with switch on the unit. By pressing the encoder switch for more than 5 seconds, the unit will enter the setup mode.This unit has a user selectable relay option for High-Low or DPDT. It can also be user-selected to energize on fault or de-energize on fault. The user can select automatic or manual restart on the Model 25. The Model 25 True RMS 3-Phase Monitor can be either calibrated using a True RMS Voltmeter or can be restored to factory defaults in the field. -
