The ASM Global Performance series of ultra-miniature
open-frame switching power supplies features 10 versions with single outputs of 3.3 to 24 V dc and a power
range of 10 to 15 W (). All of the models accept inputs of 90 to 264 V ac. The supplies, which incorporate corner mounting holes, are connector pinout and mounting-size compatible
with more expensive industry-standard products.
The ASM series' single-sided construction ensures high reliability. The supplies include an integral power-good LED indicator and an output-adjustment potentiometer. Each supply contains short-circuit protection circuitry as well as internal input filtering. Also, the
ASM series is approved to EN60601-1/UL2601 medical safety
specifications. All of its models operate at an ambient temperature of 0°C to 50°C without forced cooling or output power derating. The power supplies are available in commercially approved
versions known as the ASL series as well.
The ASM Global Performance power supplies come in sizes
as small as 2.28 by 2 by 0.56 in. (10 W). All of the devices
incorporate min-size Molex style I/O connections. Prices start
at $29 in OEM quantities. Delivery is stock to six weeks.

Power Supplies
Featuring 60-W single outputs, the five models in MicroPower Direct's HF60W-SL family of compact ac-dc power supplies deliver
5, 12, 15, 24, and 48 V dc from a universal ac input of 85 to 264 V
dc. EN60950-approved and CE-certified, they have a line/load regulation of less than 0.5%, 3000-V ac I/O isolation, a 20-ms holdup
time, and high efficiency. They're protected against output overload
and overvoltage, and the output is adjustable by ±10%. Also, their
mean time between failures (per MIL HDBK 217F) is greater than
100,000 hrs. For more, check out www.micropowerdirect.com.
The PTH04T220/221W is a lower-input-voltage (2.2- to 5.5-V) version of the PTH08T220/221W (4.5- to 14-V) 16-A non-isolated
power-supply module from Texas Instruments. The modules
require just one resistor to set their output voltage to between 0.69 and 3.6 V. Other features optimize the regulator's transient
response while reducing the number of external capacitors needed to meet a target voltage deviation and allow for switching frequency synchronization of multiple modules. For more information, go to www.ti.com.
Designed for ATCA systems, the Artesyn ATC210 integrated bus converter module occupies 20% to 40% less space than competitive solutions, according to Emerson Network Power. It combines
a high power-density isolated dc-dc converter with advanced digitally programmable power-management functions in a 2.3- by 1.8in. footprint. Also, the ATC210 is rated at 210 W, and full-load efficiency is 89%. It generates a 12-V, 17.5-A output to power an
on-card intermediate bus and a 1.8-A, resistor-programmable 3.13- to 3.47-V output for supplying peripheral management circuitry. It costs $148 in 1000-piece quantities. Delivery is stock to
eight weeks. Check out www.GoToEmerson.com.
