Tumbler Technologies, Inc. + TRUMPower has added the BF-class TIM250-S series of AC/DC switching power supplies to its range of AC/DC switching power supplies, which meet medical and ITE safety requirements and are highly adaptable to multiple applications with different configuration possibilities. It can provide 250W output power under 18CFM forced ventilation.
The PCB version of the power supply has a compact 4.09 "(L) x 2.13" (W) x 1.26 "(H) footprint. The power supply provides three single output voltages of 12V, 24V, and 48V, and can be equipped with various output connector types. To increase its versatility, the series is available in a variety of forms, from open-frame PCBS, U-mounts to enclosed (U-mounts with covers) and top mounted fans.
According to Telcordia (Bellcore TR-332) calculations, the power supply has a minimum MTBF of 350,000 hours at full load at 25C, which is very reliable. Power supplies operate between 90-264VAC, ambient temperatures range from -20 ° C to +70 ° C, and are standard with 2 x MOPP BF insulation rating. The unit is best suited for ITE class essential applications at 5000 m and medical class applications at 3000 m. It typically achieves 93% efficiency at 230VAC, full load.
The series has been certified to the latest medical standards, including UL/IEC/EN 60601-1 Version 3.1 and the latest ITE grade standard UL/IEC/EN 62368-1. The power supply complies with IEC/EN 60601-1-2 4th edition medical EMC and immunity standards, EN 55011, EN 55024, EN 55032, EN 61000-3-2, EN 61000-3-3, EN 61000-4-2 (ESD in ±15kV air and ±8kV contact), EN 61000-4-3, EN 61000-4-4, EN 61000-4-5, EN 61000-4-6, EN 61000-4-8 and EN 61000-4-11.
