JPR Electronics adds encapsulated switch mode power supplies
Encapsulated switch mode power supplies, the Myrra 47000 and 48000, are available from specialist distributor JPR Electronics
The Myrra 47000 is a range of encapsulated, PCB mountable power supplies ranging from 1.0 to 60W. The range includes power supplies with VDE and UL approvals, are CE marked and meet class B EMC standards without any additional external components.
The power supplies offer an alternative to traditional discrete component designs, says JPR Electronics, providing reduced component count and saving PCB space. The 2.4 to 5.0W range provides a form-fit-and-function replacement for EI30 type transformer-based power supplies.
The 48000 series is a compact design – it measures 25 x 25 x 16mm – and provides power from 1.0 to 3.0W. The series also has VDE and UL certification and is EMC compliant.
The 47000 series comprises compact PCB mount devices which are available with output power from 2.4 to 60W and single outputs from 5.0 to 24V DC. The input range is 85 to 265V AC at 47 to 63Hz or 120 to 370V DC. The low standby power consumption and high efficiencies ensure the series meet the requirements of Energy Star, confirms JPR Electronics.
The encapsulated switched mode power supplies are based on flyback topology with the enclosure manufactured from UL 94-V0 plastic and resin. They meet all requirements of IEC/EN61558-2-16, IEC/EN62638, IEC/EN60335, UCUL60950 and are CE marked. Conducted and radiated EMC emissions conform to EN55014, EN55032, CLASS B, EN61000-3-2 CLASS A, EN61000-3-3, IEC61000-4-2, IEC61000-4-3, IEC61000-4-4, IEC61000-4-5, IEC61000-4-6 and IEC61000-4-11
Applications include alternatives to linear transformer designs in many AC/DC power supplies, replacements for DC/DC converters for point of load power sources, industrial, domestic and consumer electronics, standby devices and DC or AC auxiliary supplies.
Paul Raynor, director of JPR Electronics, commented: “Myrra encapsulated power supplies allow customers to upgrade their products without having to redesign PCBs. In the same package as an EI30 transformer, they can replace a transformer, bridge rectifier -filter capacitor and fuse, additionally in regulated power supplies the linear regulator and heatsink can be eliminated.”
