Setra Systems has unveiled its split core magnetic current sensing technology, found within its Current Transducer (CTC) Series.
According to the company, the sensing technology provides cost-effective, high-accuracy measurement of electrical current up to 150 Amps. Such current typically may be found running through the cables and wires used within HVAC/R and industrial applications, including refrigeration units, air handlers, compressors, pumps, fans, small industrial motors and lighting. Offered in three models, the CTC Series features a three-position slide switch for user selection of the best amperage range for individual applications. Available versions include industry standard 4-20 mA and 0-5V outputs, both with 30/60/120 Amp selectable range; and a 0-10V output version with 20/100/150 Amp selectable range. They are also available in both 24 VDC loop- and self-powered versions. Total measurement accuracy is ±2% of selected range, with an isolation rating of up to 600 VAC RMS.
The series clamped split core and self-gripping iris fingers design allows for the magnetic current transducer to grip onto the cable without additional support. In addition, the series is directly compatible with a snap-on command relay. Two optional power relay modules with LED indicators, sold separately as Models CCR-24 (24VAC/VDC) and CCR-12 (12VAC/VDC) are available for remote motor startups. Designed for onsite mechanical attachment to the CTC Series, Model CCR relays provide a cost-effective solution for load switching without the need to mount an external relay elsewhere in the control enclosure.
