NOTE: Available only until stock is depleted.However, the
OPTOEMU-ACT-1250-400is a drop-in replacement with additional features.
The OPTOEMU-CTS-1250-400 current transformer (CT) from Continental Control Systems offers an easy, safe, and inexpensive method for monitoring electrical energy usage. It is recommended for use with the
OptoEMU Sensor.
This CT has a 400 amp primary and a 0.333 VAC secondary. Its inner diameter is 1.25 inches (3.18 cm). Ideal for retrofit applications, the split core makes it possible to attach the CT without disturbing existing wiring. Just open the CT, slip it over the wire, and snap the CT closed. Once assembled, the CTs have no exposed metal parts.
The 0.333 VAC output of this CTs is low, making it much more safe to install and use than CTs with current secondaries. Voltage CTs are also less expensive.
虽然比电流次级的CT少于CT,因此并不是为计量应用而设计的,而计量应用需要高精度,但这些CTS从额定电流的10%到130%的准确性至±1%。这种准确性非常适合能源监测应用。
The CT has an internal precision burden resistor across the secondary and is core interleaved at joints for accuracy. Phase angle is measured at 50% of rated current. The CT has an epoxy-encapsulated housing and includes 8-foot-long, twisted-pair, 22 AWG leads.
