SL Power – 110W AC-DC power supplies offer superior EMC performance and high surge immunity


SL Power-Logo-1-97874
SL Power Electronics has introduced the new TB110 series of internal power supplies, part of its comprehensive range of power solutions for noise- sensitive test and measurement equipment.

The new TB110 series models offer up to 90% efficiency, and are available in a small 2.0” x 4.0” x 1.4” form factor, ideal for use in 1U chassis applications. They comply with the strictest requirements of the EN61000- 4-x standards, to enable designers to readily implement power systems that comply with EMC regulations. They meet the Class B requirements for conducted EMI with a 6dB margin, and for radiated EMI with a 3dB
margin. The products also offer 4kV surge immunity.

Long life and reliability are other notable features of the TB110 series. Mean time before failure at a temperature of 50°C is calculated to be longer than 1 million hours. In addition, capacitor life is rated at longer than 15 years at an ambient temperature of 40°C.

Operating from an input- voltage range of 90V-264V AC, the TB110 products supply up to 110W of output power with airflow, and 80W when convection-cooled.

They are available in versions with outputs of 12V, 24V or 48V. All models are CE-marked for compliance with the low-voltage directive and approved to the ITE standards of CSA/EN/IEC/ UL60950-1, 2nd Edition, Amendment 2.
