Tucson, Ariz. C&D Technologies has introduced a new series of current sensing transformers designed to measure and monitor AC currents.
Combining an isolation voltage of 500 Vdc and a primary current rating of 10A, the 5600 series devices are suitable for use in applications including switched mode power supplies, motor current load monitoring, lighting and instrumentation. When used in switched mode power supplies, the transformers act as feedback elements between the output and pulse control circuitry to provide accurate regulation.
Available in 50, 100, 200 and 300 turn variants, the new transformers have an operating frequency range of 20 kHz to 200 kHz. Center tapped versions are also available, which reduce component count in the full wave analysis configuration.
Measuring 16.79 x 20.19 x 8.89 mm, the new series provides an inductance value range from 5 mH to 335 mH with DC resistance values from 117 mΩ to 8.59Ω. The standard operating temperature range is -40°C to 85°C.
Pricing for the transformers is less than $1.00 in OEM quantities.
