Versatile AC/DC power supply has dual medical and ITE safety approvals

Tumbler Technologies, Inc. + TRUMPower has added the BF rated TIM250-S series power supply, able to deliver 250W of output power at 18CFM forced air, to its AC/DC switching power supply line-up. The series satisfies medical and ITE safety requirements and is highly adaptable to multiple applications with different configuration possibilities.

This power supply is offered in three single output voltages of 12V, 24V, or 48V and can be equipped with various output connector types. To add to its versatility, the series is offered in multiple form factors, from open frame PCB, U-bracket to enclosed (U-bracket with cover) and enclosed with a top-mounted fan. The PCB version of the power supply comes in a compact 4.09” (L) x 2.13” (W) x 1.26” (H) footprint.

The power supply operates between 90-264VAC at ambient temperatures ranging from -20C to +70C and comes standard with 2 x MOPP BF rated insulation. The unit is ideal for operating at 5,000m maximum altitude for ITE grade necessities and 3,000m for medical grade applications. It attains an efficiency of 93% typically @ 230VAC, full load. The power supply is exceptionally reliable with its 350,000 hours-minimum MTBF at full load at 25C ambient, calculated per Telcordia (Bellcore TR-332).

The series is certified for the latest medical standards, including UL/IEC/EN 60601-1 Edition 3.1 and the latest ITE grade standards of 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 at ±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.
