The unit can deliver its full rated output of 130W with 850 litre/min forced air or 80W with convection cooling.
Featuring active power factor correction to minimise input harmonic distortion, the LPS122 is a compact 85-264V AC power supply that is ideal for 1U (1.75in) rack installations and other low-profile applications.
This compact low power switcher is well suited for a wide range of uses including telecommunications, networking, test and measurement, single-board computers and gigabit Ethernet devices.
Only 1.29in high, the LPS122 has a compact footprint of only 3 x 5in and can be set up for lengthwise or crosswise airflow, giving designers layout flexibility.
The device also features a 12V 1/2A auxiliary output and 5V at 1/2A standby output, as well as overload, overvoltage and thermal protection.
The new device includes a built-in Class B EMI filter, remote sense, remote inhibit and single-wire parallel on the primary output that enables current-sharing to balance loads.
Units offer an operating temperature range of zero to 50C without derating and can function up to 70C by derating the output 2.5%/C.
It includes IEC EN61000-3-2 harmonic and IEC EN61000-4-X susceptibility compliance.
The LPS122 demonstrates a mean time between failures (MTBF) of over 550kh at full load in 25C ambient conditions.
It also complies with worldwide safety and performance standards from UL, CSA, VDE, NEMKO, CB and CE.
Samples are available now with prices starting at $95 in OEM quantities.
