Phihong (Fremont, CA) announced its new PSS22U adapter switching power supply with a low leakage current of less than 0.1mA at 264Vac that provides medical design engineers with a reliable adapter for their power supply solutions with a low leakage current. The adapter delivers up to 24W of power for many standard models with output voltages from 3.3V to 24.0V.
The adapter measures 4.3in x 2.28in x 1.27in and weighs 206g (6,023oz). Featuring all standard medical approvals, the adapter delivers universal ac input and EMI Class B approvals. The PSS22U adapter is designed for use in blood and fluid analyzers and non-patient contact instruments. With efficiency at 80 percent, the PSS22U adapter exhibits a hold-up time of 16mS at 115Vac and 64mS at 230Vac. The adapter’s overload protection delivers from 115 to 130 percent of maximum power during short-circuit or power fold-back conditions and is self-recovering. The PSS22U adapter’s output voltage returns in less than 3mS following a 50-percent load change.
The PSS22U adapter's input accepts 90Vac to 264Vac with frequencies from 47Hz to 63Hz.
Safety approvals include UL2601 Class 1, CE, IEC 601 and EN 60601. Pricing is $19.75 per 1,000 pieces with lead times of 12 weeks. Samples will be available in July 2002.
