C&D Technologies Intros 5600 Range Transformer Series

C&D Technologies Inc. (Tucson, AZ) introduced a new series of current-sensing transformers, the 5600 range, which is designed to measure and monitor ac currents. Combining an isolation voltage of 500 Vdc and a primary current rating of 10 A, the 5600 range is suitable for use in applications, including switched-mode power supplies, motor current load monitoring, lighting and instrumentation.

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 of the 5600 Series are also available, reducing component count in the full-wave analysis configuration. The operating temperature range for the 5600 Series is from –40 °C to +85 °C, and overall dimensions are 16.79 mm x 20.19 mm x 8.89 mm.

When used in switched-mode power supplies, the transformers act as feedback elements between the output and pulse-control circuitry, providing accurate regulation. Parts from the series have inductance values from 5 mH to 335 mH, while dc resistance values range from 117 mΩ to 8.59 Ω.

Available now, pricing for the 5600 Series transformers is under $1.00 in OEM quantities.
