SL Power Introduces High Efficiency Internal and External AC/DC Power Supplies

SL-1SL Power Electronics added the TE60 and TB65 series product lines to its line of power solutions for test & measurement applications. The 60 watt TE series external power supply complies with the US Department of Energy’s level VI efficiency requirements and provides enhanced performance to meet strict EMI and EMC parameters. This design makes these external power supplies a solution for use with handheld test and measurement and industrial devices, where low noise and rugged performance are required.

In addition to Level VI compliance, equipment designers will appreciate that the TE series meets the “heavy” industrial levels of EMC per EN61000-4-X, protecting end-use equipment from harsh electrical environments. Moreover, the TE Series designs utilize high-quality electrolytic capacitors, ensuring greater than seven-year product life. Low common mode noise, level 4 ESD protection (IEC61000-4-2: 8 kV/15 kV) and surge protection (IEC61000-4-5: 1  kV CM/4 kV DM) help to ensure the highest overall performance.

The desktop and wall plug models offer regulated output power with low ripple, no-load power consumption >0.5 W, and short circuit and thermal protection. They include Class B EMI filtering with a minimum of 6 db (conducted) and 3 db (radiated) margin and a convenient IEC AC 320 C14 grounded input connector that can accept input line cords with any appropriate plug configuration.

For internal power, the TB65 models offer up to 90 percent efficiency and a compact form factor.  Measuring 2.0 by 3.5 by 1.3 inches, for use in a 1U chassis, the TB65 provides up to 65 watts of convection-cooled output power. The TB65 internal power supply is compliant to high levels of EMC per EN61000-4 and meets Class B conducted EMI with 6db margin and Class B Radiated EMI with 3 db margin. Feature rich with up to 90 percent efficiency, designers of test equipment will appreciate the TB65’s greater than 10-year life, based on e-cap calculations.

The TB65 models feature a universal input of 90 to 264Vac and are available in outputs of 12V, 15V, 24V and 48V. DC OK Signal and PSU temperature monitoring signal are standard offerings. All models are CE marked to low-voltage directive and approved to ITE standards of CSA/EN/IEC/UL60950-1, 2nd Edition, Am. 2.
