Production Specification

NOTE: Available until stock is depleted. When stock is depleted, use OPTOEMU-ACT-0750-100.

The OPTOEMU-CTS-0750-70 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 70 amp primary and a 0.333 VAC secondary. Its inner diameter is 0.75 inch (1.91 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.

While somewhat less accurate than CTs with a current secondary and therefore not designed for metering applications where high accuracy is necessary for billing purposes, these CTs are accurate to ± 1% from 10% to 130% of rated current. This level of accuracy is well suited to energy monitoring applications.

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.

Pulse Energy Quick Start

Pulse Energy is an online service you can use to view data about your electrical energy usage. Support for Pulse Energy is integrated into the OptoEMU Sensor™; however, if you are not using the Sensor but acquiring energy data using the SNAP PAC System, you can still see that data through Pulse Energy.

This sample chart shows you how to move data from PAC Control into Pulse. Import the included chart into your PAC Control strategy to make integration with a Pulse Energy account easier. The included technical note, form 1992, shows you how to configure a Pulse Energy account and use the chart to visualize your monitored energy values.
