Emerson Network Power Launches Triple Output, Low Power Switcher
Emerson Network Power has introduced a new line of compact, triple-output 50W switching power supplies from Astec Power. The new Astec LPT50 Series accepts universal input voltage (90-264Vdc or 127-300Vdc) and frequency (47-440Hz) to provide a selection of standard dc positive outputs from 3.3V to 24V depending on the model.
With a compact footprint of only 2 inches by 4 inches, the LPT50 units are rated for convection cooling and offer 5.5W per cubic inch. They can deliver up to 9 amps from the primary output. Featuring overpower and short circuit protection along with CISPR 22 Class B EMI filtering. The LPT50 series is also available with medical safety certifications designated by a -M on the model number.
Designed for 1U installations, the new models address the needs of network, telecom, medical electronics and industrial equipment designers who require cost effective power solutions that assure reliability. With more than 550,000 hours of demonstrated Mean Time Between Failures (MTBF), the LPT50 Series offers high efficiency and includes over-voltage protection on the main output. They include a "power good" LED indicator. The robust designs of the LPT50 Series models comply with major worldwide safety and performance standards including UL, CSA, TUV, as well as the EN61000-X susceptibility requirements. In addition the units feature a wide operating temperature range of 0 to 50°C, with a -20°C startup. Samples are available now with prices starting at $28.00 in OEM quantities.
