Gresham Power Electronics introduces the SL Power TE and TB series of high efficiency internal and external AC/DC power supplies for test and measurement, industrial and ITE devices. The TE series meets CEC Level VI Energy Efficiency Standards which come into effect on 10th February, 2016 and will have to be met by OEM manufacturers intending to market their products into the USA.
The TE60 are external power supplies with output power ranging from 10 to 60W with higher power versions to follow. The TB65 open frame versions offer superior EMC/EMI compliance, RF and surge Immunity. All models feature an industry leading three-year warranty.
The series external power supply complies with the U.S. 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 a suitable 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 utilise high-quality electrolytic capacitors, ensuring greater than seven-year product life. 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.
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.
The TB65 open frame versions offer superior EMC/EMI compliance, RF and surge Immunity. All models feature an industry leading three-year warranty and provide up to 90% efficiency in a very compact form factor. The TB65 power supplies are the suitable power solution when very high efficiency and superior EMI and EMC performance are required. Measuring only 2.0x3.5x1.3” for use in a 1U chassis.
The TB65 provides up to 65W of convection-cooled output power, is compliant to high levels of EMC to EN61000-4 meeting Class B conducted EMI with 6db margin and Class B radiated EMI with 3db margin. Designers of test equipment will especially appreciate the TB65’s greater than 10 year life, based on e-cap calculations.
“These new SL Power CEC VI compliant power supplies are available now to designers with new products to be launched in 2016. They offer superior EMI, EMC, ESD, surge and radiated noise performance for instrumentation and test equipment.” said Dave Wellman, Sales Manager, Gresham Power Electronics. “The high performance TB65 internal models address problematic interference and susceptibility issues ensuring smoother end-product design and faster time to market of end systems. The new TE models are a market leading external power supply solution when the highest level of efficiency, EMI and EMC performance are required.”
The TB65 models feature a universal input of 90 to 264VAC and are available in outputs of 12, 15, 24 and 48V. DC OK and PSU temperature monitoring signals are standard features. All models are CE marked to low-voltage directive and approved to ITE standards of CSA/EN/IEC/UL60950- 1, 2nd Edition, Am. 2.
