Power supplies for test and measurement

| Environmental Testing

Energy efficiency and enhanced EMI performance characterise new external and internal power supplies for use in test and measurement applications.

SL Power Electronics is adding the TE60 and TB65 Series product lines to its power supplies for test & measurement applications.

TE60 for external power

The new 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 high-performance design makes these external power supplies ideal 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 utilise high-quality electrolytic capacitors, ensuring a product life of greater than seven years. Low common mode noise, level 4 ESD protection (IEC61000-4-2: 8kV/15kV) and surge protection (IEC61000-4-5: 1kV CM/4kV 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 >0.5W, and short circuit and thermal protection. They include Class B EMI filtering with a minimum of 6db (conducted) and 3db (radiated) margin and a convenient IEC AC 320 C14 grounded input connector that can accept input line cords with any appropriate plug configuration.

TB65 for internal power

For internal power, the TB65 models offer up to 90 percent efficiency and a very compact form factor. The 65-watt TB65 power supplies are ideal when very high efficiency and superior EMI and EMC performance are required. Capable of being fitted in a 1U rack mount 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 3db margin. Feature rich with up to 90 percent efficiency, designers of test equipment will especially appreciate the TB65’s greater than 10-year life, based on e-cap calculations.

“Our newest external and internal power supplies have been specifically designed to meet test equipment designers’ need to solve challenging issues with EMI, EMC, ESD, surge and radiated noise,” said Paul Kingsepp, product manager for SL Power Electronics. “Our high performance TB65 internal models address problematic interference and susceptibility issues ensuring smoother end-product design and faster go-to-market time. Our new TE Series models are perfect external power supplies when the highest level of efficiency, EMI and EMC performance are required.”
