Trump extends AC/DC switching power supplies with TWM150 series
AC/DC switching power supplies from Trumpower now include the TWM150 series. It is capable of delivering 100W of continuous output power at convection and 150W maximum output with 10 CFM of forced air cooling. The TWM150 series is certified to the medical and ITE standards.
The power supply series is available in an open frame, U-bracket, or enclosed form factor. They offer high power density in footprints of 3.0 x 2.0 x 1.18 inch (76 x 50 x 30mm) for the open frame model, 3.0 x 2.0 x 1.5 inch (76 x 50 x 38mm for the U-bracket and 3.0 x 2.0 x 1.54 inch (76 x 50 x 3.9mm for the enclosed form factors. The power supply series has eight standard single output voltages between 12 and 54V.
The TWM150 series power supplies operate between 90 to 264V AC at ambient temperatures ranging from -20 to +70 degrees C with full power available up to +50 degrees C at 10 CFM and +40 degrees C at convection mode. Active efficiency is 92 per cent minimum at full load and the power supplies are capable of operating at 5,000 meters maximum altitude for ITE grade applications and 3,000 meters maximum altitude for medical grade purposes. The power supplies are BF-rated and have a withstand voltage specified at 4,000V AC from input/output (2 x MOPP), 1,500V AC from input-ground and 1,500V AC from output-ground. The power supply’s 250,000 hours minimum MTBF at full load at 25 degrees C ambient temperature calculated per Bellcore TR-332.
The TWM150 is certified to the latest UL/IEC/EN 60601-1 Edition 3.1 medical standards and adheres to ITE Standards of UL/IEC/EN 62368-1 2nd edition. The power supply complies with IEC/EN 60601-1-2 4th edition medical EMC and immunity standards including EN 55011 class B, EN 55032 class B, EN 55024, FCC part 15 class B, and FCC part 18 class B.
Trumpower has been supplying medical and industrial grade AC/DC switching power supplies and DC/DC converters since 1991. The company’s medical grade power supplies range from 4.0 to 1,200W and its line of ITE grade AC/DC power supplies range from 3W to 1400W in wall mount, desktop, open frame, and ATX PC form factors.
