| MODEL 275 Single Phase Current Monitor |
| Series Description: The Model 275 Single Phase Current Monitor is designed for monitoring alternating current in the range of 1-5 amps, at 50 to 400 Hz. The Model 275 provides a contact transfer when the set current level is exceeded for a period longer than the time delay. The OVER-CURRENT indicator illuminates immediately. After the time delay, the TRIPPED indicator lights and the relay contact transfers. This device can directly monitor AC currents in the range of 1 to 5 amps; 50 to 400 Hz. Matching transformers are available to extend the use of this monitor to most any current range. The Model 275 is available with automatic or manual reset. Operating power is supplied by separate 24 or 120 volt power supply. |
