Bel's New ``Stretched'' 1/4 Brick dc-dc Converter for Telecom Applications: 450 Watt Converter Features Integrated Heatsink and High Efficiency to 94.5%.JERSEY CITY, N.J. -- Bel (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :BELFA)(NASDAQ:BELFB), a premier designer and manufacturer of modular non-isolated and isolated power dc-dc converters for high-speed networking, telecommunications, and computing applications, today announced the addition of the GALW9V647 450 W single output dc-dc converter to their Bel Power Inc. product line. This "stretched" 1/4 brick converter, the newest member of the Sirius family of board-mounted CoolConverter(TM) power modules, measures 1.45" x 4.25" x 0.95", including a built-in heatsink for improved thermal performance. The part's open-frame, single-board integrated construction offers engineers and EOEMs the utmost in PCB PCB: see polychlorinated biphenyl. PCB in full polychlorinated biphenyl Any of a class of highly stable organic compounds prepared by the reaction of chlorine with biphenyl, a two-ring compound. space conservation, design flexibility, and manufacturing throughput. Microprocessor-controlled, the device boasts a proprietary single-stage power supply control, and architecture that uses synchronous rectification to achieve extremely high conversion efficiencies. Notably, the converter's constant switching frequency enables very low common mode noise operation, and its circuitry provides very low ripple. Highly applicable for employment in demanding telecom, networking, and wireless applications requiring high current, low voltage Low voltage is an electrical engineering term that broadly identifies safety considerations of an electricity supply system based on the voltage used. While different definitions exist for the exact voltage range covered by "low voltage", the most commonly used ones include "mains , and fast transient-response times, Bel's newest power module has an operating efficiency of 93.5% at full load, and 94.5% at half load. The dc-dc converter features a wide input voltage range from 36 to 75 VDC VDC Volts Direct Current VDC Venture Development Corporation VDC Vehicle Dynamic Control VDC Village Development Committee (Nepal) VDC Virtual Data Center VdC Verband der Cigarettenindustrie and a single isolated output of 9.6 VDC. Output current is rated up to 47 A, while line and load regulation is +/- 0.2% and 2%, respectively. Setpoint accuracy is +/- 5%. Offering full protection features, the GALW9V647 provides under voltage lockout lockout, intentional closing up of a company, factory, or shop by an employer to prevent employees from working during a strike or labor dispute. The term lockout with hysteresis hysteresis (hĭs'tərē`sĭs), phenomenon in which the response of a physical system to an external influence depends not only on the present magnitude of that influence but also on the previous history of the system. to prevent false starting and stopping at low input voltages, and over temperature, over current, and over voltage protection. The THT THT The Hardball Times (baseball website) THT Terrence Higgins Trust (UK HIV/AIDS charity) THT Through Hole Technology THT The Human Touch THT Technische Hogeschool Twente module also boasts output voltage trim adjustment, a two-stage input filter, and primary side on/off. It operates over a wide, ambient temperature Outside temperature at any given altitude, preferably expressed in degrees centigrade. range of -40 degrees C to +100 degrees C, and carries a full set of international safety approvals, including EN60950 and UL/cUL60950. Pricing for Bel's GALW9V647 dc-dc converter starts at $150.00 each in quantities of 1,000. While delivery is 8 weeks, samples are immediately available.
