Time Mark 20-Series, 3-Phase-Monitor

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.  Typical Application Dimensions Manuals/Guides Spec Sheets Time Mark 20 3 Phase Monitor with Adjustable Trip and Restart Delays Data Sheet Manufacturer Specs General Specification Auto Reset Models Manual Reset Models* 2020M 20-L20-LM 20-H20-HM Operating Voltage 190-480 VAC 95-120 VAC 475-600 VAC Power Consumption 3.7W at 480V 3.7W at 120V 4.5W at 600V Auto Ranges Yes No Frequency 50/60Hz Type of Measurement RMS Under VoltageTripReset (% of setpoint)90% ±1%93% ±1% Over VoltageTripReset (% of setpoint)110% ±1%107% ±1% Voltage Unbalance TripReset (conforms to NEMA)2-8%, adjustableTrip setting minus 0.7% Trip Delay TimeOver, Under, & Unbalanced Single-Phasing Faults Unbalance > 15% 1-30 sec., adjustable1 sec., fixed1 sec., fixed Restart Delay 1-500 sec., adjustable Manual Reset Input 5V open circuit/500µA short circuit Output Contacts SPDT 10 amps at 240VAC resistive Operating Temp - 20º to +140º F Humidity Tolerance 0-97% w/o condensation Terminal Torque 3.5 in. lbs. maximum Wire Type Stranded or solid 14-26 AWG, 1/terminal Enclosure Noryl plastic Mounting DIN Rail or Surface Mount Weight 11 oz.
