Time Mark 20 3-Phase Monitor with Adjustable Trip
& Restart Delays

3 Phase Monitor

Microcontroller-based
Adjustable trip and restart delays
LED status
Automatic or manual restart versions

The Model 20 is a microcontroller-based universal 3-phase monitor for protecting 3-phase motors from abnormal power conditions. It can detect under voltage, over voltage, voltage unbalance, reverse phase, and single-phasing even when regenerated voltage is present. The Model 20 includes adjustable trip and restart delays to prevent nuisance tripping during power fluctuations and short cycling in compressor applications. The LED status indicators and adjustment pots for Voltage Adjustment, % Unbalance, Restart Delay and Trip Delay are mounted on the front of the unit for easy access.

The Model 20 is UL Recognized in the U.S. and Canada. Automatic or manual restart versions are available. The Model 20 does not require a neutral connection and can be used on either Wye or Delta systems.
