Quarter-Brick Series Converters |
Emerson introduces the LQS quarter-brick series whose design takes advantage of the open-frame construction |
|
| Emerson's high efficiency, open frame, LQS quarter-brick series delivers very high output current at low voltages, as well as excellent useable output power for today's high-end applications. The design takes advantage of open-frame construction to provide a low mass, low thermal impedance single board design. This series features an input voltage range of 36 Vdc to 75 Vdc and output voltages of 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V. The output voltage on each model is adjustable from 80% to 110% of the nominal value. Typical efficiency for the 1.8 V model is 90%. This converter also has a remote ON/OFF capability. Overcurrent and overvoltage protection features are included as standard. With full international safety approval including EN60950-1 VDE and UL/cUL60950, the quarter-brick converter reduces compliance costs and time to market. |  |
