AC current sensors replace CTs

3 March 2010 Test & Measurement

Expanding its ISOpro isolation product portfolio, Silicon Laboratories has introduced a next-generation AC current sensor family that replaces traditional current transformers.

The new Si85xx current sensors provide up to 5 kVrms of electrical isolation to ensure safety compliance for a variety of critical power delivery systems such as AC-DC switching power supplies, isolated DC-DC supplies, motor control applications and electronic lighting ballasts.

With a measurement accuracy of better than 5%, the new sensors are available in 5 A, 10 A and 20 A versions. They provide a large output signal level of 2,0 V at full-scale output range, eliminating the need for an external amplifier. A ‘ping-pong’ output mode enables one sensor to replace two current transformers and associated components in full-bridge applications. The devices’ low resistance (<1,3 milliohms) and small parasitic inductance (<2 nH) result in highly efficient power supplies.
