CME420 |
 Current relay
|
|
The CME420 series monitors for undercurrent and overcurrent in AC systems, as well as the current between two threshold values. True RMS values are read by the device. Values are displayed in real-time on the digital LCD screen. Trip levels are explicity set via the digital display. Settings allow for latching or non-latching operation.
Up to 16 A of current can be monitored when directly connected to the system. Optional current transformer connections greatly expand this range. When x/5 ratio current transformers are used, the CME420 can be programmed with this ratio to allow explicit values to be set instead of doing calculations by hand. An external supply voltage is required.

CSD230 |
Current relay
|
|
The CSD23X series monitors for overcurrent in three-phase systems. Measurements are taken directly and indirectly via measuring current transformers. External supply voltage is required.

CSG140 |
Current relay
|
|
The CSG140 series monitors for undercurrent in DC systems. The current is measured either directly or by means of a shunt. The response value, response delay, and hysteresis are set via potentiometers. External supply voltage is required.
