R0D2728 Datasheet
R0D2728 Price RSENSE Selection for Output Current RSENSE is chosen based on the required output current. The LTC1149 series current comparator has a threshold range which extends from a minimum of 25mV/RSENSE to a maximum of 150mV/RSENSE The current comparator threshold sets the peak of the inductor ripple current, yielding a maximum output current IMAX equal to the peak value less half the peak-to-peak ripple current. For proper Burst Mode operation, /RIPPLE(P-P) 177ust be less than or equal to the minimum current comparator threshold. R0D2728 on stock I Calflam CWZ Benefits Conductors - Calflam CWZ uses stranded conductors many other fire alarm cables have solid conductors which are stiff and can have a "cheese wire eftect" contributing to shorts after installation. Calflam CWZ has more flexible conductors which contributes to ease of installation in tight panel areas Fire Barrier - Calflam CWZ incorporates a mica glass fire barrier over each conductor other fire alarm cables use only one, overall mica glass fire barrier Insulation - CalflamjCWZ uses XLPE as its insulation, XLPE is extremely strong mechanically. Many silicor,e rubber cables are prone to core to core shortmg due to rough installation techr<iques. Identification - Each core is numbered with indelible printing aiding mstallation and elimmatmg the need for labels or ferrules Screen - Calflam CWZ uses a convenhonal 100'Io spirally apphed tape screen unlike some alarm cables wruch have a stiff solid alumimum screen that can contribute through sharp edges to core to screen shorts Outer Sheath - Mechamcally strong FR LSOH, embossed "Calflex Cables - Calflam CWZ" Indelible mk printing is available upon request Intrinsically Safe - The inductance over resistance ratio of Calflam CWZ is lower than that specified witFun B55308, thus making the cable suitable for use m hazardous areas where intnnsically safe circuits are required Electrical Performance - The capaatance characteristics of Calflam CWZ are much lower than other fire alarm cables currently available. This enables greater panel to panel distances and higher transnussion rates Calflam CWZ is ideal for data transmission and for use on "Addressable Alarm Systems". Ease of Installation - Calflam CWZ can be installed using conventional techniques used for mstrument/data cables. Special tools and terminations are not required. Colours - Calflam CWZ is available m all colours, standard stock colours are red and white Availability - Calflam CWZ is available from stock m all sizes, a fullinventory is held in our U.K. warehouse. Calflam CWZ is stocked in either 500m or 1000m drum lengths. The PT500 Series is a family of compact, fully featured, multiple-output 500W power supplies with a 3.3V main output. These high-current, 3.3V output platforms will support requirements in which the logic has largely migrated from SV t0 3.3V With active Power Factor Correction (PFC) to EN61000- 3-2, wide-range input of 90-264VAC, EMI compliance to FCC and VDE Class B, and "CE" Marking, the PT500 Series is ideal for systems targeting worldwide markets. The complement ofstandard features includes remote sense compensation, output voltage adjustment, remote inhibit, power fail warning, and thermal shutdown. All outputs are fully isolated and regulated. A complete array of output voltage configurations is available to handle a broad range of applications. Available options include a cover with integral fan and active current sharing for redundant applications. |
