279C-120
Categories: 279-Series, Current-MonitorsThe Model 279 DC Current Monitor is a single set-point DC current monitor. It can sense either 1-10 Amps DC (24VAC or 120VAC) or 0.1-1 Amps DC (120VAC). The units have an input frequency of 50/60 Hz. The standard version, the 279B, has a screwdriver adjustable trip and hysteresis setting on top of the device. The hysteresis setting adjusts from 0% to 100%, and can be set fully clockwise for manual reset operation. A remote adjust version, the 279C, has a remote trip adjustment and a remote reset button. An LED indicator is provided on both versions to indicate when the relay is energized (current above the trip setting. )
The 279B plugs into a standard 8-pin octal socket; the 279C plugs into a standard 11-pin socket.

Single Phase Over/Under Current Monitor2 to 10ASelect optionsThe Model 273 Single Phase Current Monitor is a single set-point sensor. It can be used as either an over current or under current sensor, depending on the contacts used. This device can directly monitor AC currents in the range of 0.5 to 5 amps: or 2 to 10 amps, 50 to 400 Hz. Matching transformers are available to extend the use of the monitor to most any range. The current being monitored can be of any voltage, up to the rating of the socket. An LED indicator is provided to show when the relay is energized. The Model 273 is available for either 24 VAC or 120 VAC supply voltages.
Model 273-5 is UL Recognized and CSA Certified. All versions use a standard 8-pin socket.

TRUE RMS Over & Under Current Monitor0 - 5ASelect optionsModel 27 True RMS Current Monitor has a display that shows the current with an accuracy of +/- 0.5%. The display is updated every second and re-initialized every 30 seconds. Model 27 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 27. The SG version of the Model 27 has silver with gold flash contacts for low current applications. Model 27 True RMS Current Monitor can be either calibrated using a True RMS Multimeter or can be restored to factory defaults in the field.
