TW150 series is upgraded to comply with IEC 62368-1 for hazards

The dual, triple, and quad output AC/DC switching power supplies in the TW150 series by Tumbler Technologies + TrumPower have been upgraded to comply with the new IEC 62368-1 standards. The hazard-based, performance-oriented standard will replace the IEC 60950-1 safety standard from 20 December 2020.

There are multiple AC/DC switching power supplies in the TW150 series. There are three standard models with dual outputs, three standard models with triple output and seven standard models configured as quadruple-output supplies. Outputs range from 3.3, 5.0,12, 15V, 24V, 28V and 48V and deliver 150W of continuous output power at 30 CFM forced air or 120W at convection cooling on open PCB and U-bracket form factors.

The compact, open frame PCB design measures just 76 x 127mm and is 34.5mm high (3.0 x 5.0 inches and 1.36 inches high) while the U-bracket version measures 76 x 127mm and is 40mm (1.57 inches) high.

Operating at a 90 to 264V AC universal input, the power supplies have over-temperature, over-load and short-circuit protection. Ambient operating temperature is 0°C to +60°C, derating linearly from 100% load at +40°C to 50% load at +60°C. MTBF is 100,000 hours (minimum) at full load, and 25°C ambient, per MIL-HDBK-217F. The power supplies’ efficiency is 80% (typical) at full load, adds Tumbler Technologies + TrumPower. The series also has an active power factor correction (PFC) of up to 0.99.

The power supply series is RoHS-compliant and approved to IEC/EN/UL 62368-1:2014, CAN/CSA 22.2 No. 62368-1-14. The TW150 AC/DC switching power supplies also comply with EMC and immunity standards including EN 55022, FCC, CISPR 22, Class B.

TrumPower was established in 1991 to supply medical and industrial grade AC/DC switching power supplies and DC/DC converters. Its medical grade power supplies range from 4W to 1200W and its line of IT equipment (ITE) -grade AC/DC power supplies ranges from 3W to 1400W. They are available as wall mount, desktop, open frame, and ATX PC form factors.

The company can meet low volume or high volume power supplies requirements and says its service is characterised by prompt responses and cost-effective power solutions.
