PRODUCT OF THE MONTH — AC/DC Power Supply

Power Partners, Athens, GA, has released a new AC/DC power supply from its medical open frame/u-channel product line. The BF-rated-output PPWAM360 series is designed to deliver 360 W in a high power density 4 × 6 in. footprint with 90–264 V AC input and five single output models (12, 24, 28, 48, and 54 V DC). The series is Class I rated and has approvals to UL/EN 60601-1, 3rd edition, for medical as well as UL/EN 60950-1, 2nd amendment ITE approvals. The series is also approved to the latest EN 60601-1-2, 4th edition, EMC medical standard.

Units are 90 percent efficient at 230 V AC input. They have <100 µA @ 264 V AC earth leakage current, 2X MOPP primary to secondary isolation, short circuit/overload/overvoltage protection, and nominimum load requirements. The power supplies have an operating temperature range of 0 to 70 °C (100 percent power to 50 °C, derating to 50 percent power at 70 °C), and mean time between failure of >250,000 hours per Bellcore TR-332 at full load and 25 °C ambient.

Flexible Epoxy

EpoxySet, Lincoln, RI, offers the EC-1006M-4, flexible epoxy for electronic pottings. The formula is UL-94V0 approved and is said to have excellent electrical insulating properties and dielectric strength. It can be cured at room temperature or with mild heat. Its lowviscosity system allows for encapsulations of even the most intricate circuits and components because it cures with very low stress. It can be temperature cycled from –55 to 120 C and has excellent resistance to mechanical and vibrational shock. The thermally conductive epoxy provides high heat dissipation, making it ideal for addressing electronic protection requirements or for potting and encapsulations that require thermal stability.

Low-Pressure, Compact Sensor

All Sensors, Morgan Hill, CA, has announced a new low-pressure sensor. The BLC series offers design engineers excellent performance over pressure ranges of ±1 inH2O through ±30 inH2O and 15 psia. The basic sensor is based on the company’s CoBeam2™ technology. The devices provide a high output signal at a low operating voltage maintaining comparable output levels to traditional equivalent basic sensing elements. This lower supply voltage enables improved warm-up shift while the CoBeam2 technology itself reduces package stress susceptibility, resulting in improved overall long-term stability.
