| Series Features |
| MODEL 273 Single Phase Current Monitor |
| Series Description: The 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. |
