XP Offers150W of RoHS-Compliant Power

XP Power has announced a compact 150W ac-dc external power supply for portable equipment that claims to offer best-in-class performance at 5.1 Watts per cubic inch power density and 88% minimum efficiency. Dubbed the AML150, the power supply is smaller than many lower power units of this type yet needs no internal or external fan to deliver full power at up to 40 °C ambient and 60% power at 70 °C.

Pricing is from $0.56 per Watt, making it competitive against many lower performance products. Specifying this 150W unit will often provide the power headroom for designers to make future upgrades to their products without having to change the power supply.

Cool running contributes to a calculated reliability of greater than 100,000 hours (MIL-HDBK-217F) and the unit is suited to applications ranging from automation and industrial control to specialist portable equipment and communication systems.

The power supply has a universal ac input (90 ­to 264 Vac) with active power factor correction to meet EN61000-3-2, -3 and a single output of 12, 15, 19, 20 or 24 Vdc. It measures 6.73 x 2.83 x 1.57 inches (171 x 72 x 40mm) and is supplied with a 70.8- inch (1800mm) power cord terminated with a 4-pin DIN plug.

Non-standard output voltages and connectors are available. The unit is fitted with an internal 4A fuse and offers overtemperature, overvoltage and overload protection as standard features.

The AML150 meets EN55022 Class B standards for radiated and conducted emissions and has the appropriate EN, UL and CSA safety approvals. Samples are available now, priced from $85 each for 1000 piece OEM orders.
