Current-Compensated Chokes for PV Inverters, SMPS and Drives

Schaffner has extended its range of common mode current compensated chokes with the introduction of its new RT series. The new open frame chokes are chokes fit between the existing very successful RN and RB series.

The new RT chokes are available with horizontal and vertical mounting options and in 2-line and 3-line versions. Standard current ranges are from 6- to 20-A with voltages up to 600Vac. The new product range enables developers to integrate great saturation behavior together with high common mode performance on to a PCB.

The wide range of 24 different combinations of layout, mounting position and current-inductance ratings makes the series a good fit for solar inverter and switch mode power supplies (SMPS).

The saturation behavior and the ability to apply forced cooling, in order to increase maximum possible current, are very useful for motor drive (VSD) applications up to 32A.

Schaffner's RT chokes comply RoHS and REACH requirements and with their open-frame construction and UL part lists are simple to certify to the most important global safety norms, including UL and ENEC.

The new RT chokes are available ex-stock all over the world through the Schaffner global distribution and sales network.
