Powersolve Expands Traco TMT Power Supply Range

Powersolve has announced extensions to the Traco TMT Series of encapsulated power modules with models from 10W to 50W. These fully encapsulated modules are available for PCB mounting with solder pins or chassis mounting with terminal blocks and optional DIN rail mounting clips. The TMT models measure 50.8mm x 33mm x 21.6mm for the 10W models and 89mm x 64mm x 32mm for the 50W models.

The entire TMT Series consists of 46 different models with four different power ranges of 10/15/30/50W and one to three outputs ranging from 3.3V to 48V DC. All models feature universal AC input (85 to 264V AC), -25C to +60C full load operating temperature range, high reliability with an MTBF in excess of 250,000 hours and a three-year product warranty.

These modules have safety class II approvals to UL 508, 60950-1 and 60601-1 and are suitable for use in a wide range of applications in commercial, industrial and medical environments.

Power Supply Units Suit CompactPCI Applications

Schroff UK has expanded its 19in Maxpowerpro range of switched-mode power supplies with the addition of the 13100-145 - a 6U model designed for high-power CompactPCI applications. The 13100-145 power supply features an output voltage of 500W and operates from a wide input voltage of 90-264V AC with PFC. It delivers output voltages of 5V, 3.3V, 12V, and -12V.

As well as incorporating a P47 connector conforming to the PICMG 2.11 CompactPCI specification, the PSU also provides the high levels of reliability demanded by typical CompactPCI applications in the communications, industrial, military and aerospace sectors. Inputs are protected against voltage transients and high inrush currents, outputs are protected against open-circuit and short-circuit conditions, and the power supply also includes over-temperature protection.

The unit is hot-swappable and active current sharing is provided on three of the outputs for parallel operation of multiple units in n+1 redundant designs or in systems requiring a higher output power. Measuring 6U high x 8HP wide x 172mm deep, the PSU is supplied with an EMC seal and a 19in front panel including handles. Schroff said the power supply achieves a typical efficiency of 84 per cent and meets the requirements of the relevant standards covering safety, EMC and mechanical stress.
