Current Devices

The CS series current devices monitor the current flowing to electrical equipment or buildings. The magnitude of this current is then converted into a linear  4-20mA or 0 to 10 VDC output signal, which can be monitored by a Building Management System. The units have jumper selectable input ranges.  These current sensors should be used in load trending (current monitoring) type applications and are fast acting, accurate, reliable, and extremely easy to install.

The CSW series of AC current devices activate a normally open (NO) contact closure via a solid-state switch whenever the monitored primary circuit current exceeds a pre-set level. Models are available to switch various load types, feature integral LEDs to indicate device power and also the switch status and can be provided in solid or split core configuration. The CSW-Axx models include a multi-turn adjustment to set the trip threshold to the desired value and the CSW-Fxx models operate as a go/no-go status indicators with a factory set minimum threshold value. The devices can monitor up to 200 Amps continuous and feature an auto-range circuit to eliminate manual jumpers. All models are UL, CE and RoHS compliant. The CSW series current switches are accurate, reliable, easy to install and require less servicing than differential pressure switches, or flow switches.The CSW series current device can be used to monitor devices with a maximum continuous operating current of up to 200 Amps and the power supply is induced from the conductor being monitored.
