BEL POWER SOLUTIONS INC Q DC-DC Converter, ±24V dc/ 2.75A Output, 14.4 → 36 V dc Input, 132W, Rack Mount, +71°C

Power-One 66W to 132W Single/Dual Output Regulated Isolated DC-DC Converter - Q Series. These Q Series compact DC-DC converters have all the necessary input and output filtering, signalling and protection features which are needed in the majority of applications. These converters provide flexible output power, high efficiency and reliabiity, low ripple and RFI noise levels, full input to input isolation, negligibe inrush current, overtemperature protection and over-/undervoltage lockout. These DC-DC conveters are designed for 19" DIN rack systems but can also be chassis-mounted using four M3 screws. 1 or 2 isolated outputs which can be series or parallel connected to provide pre-set voltages of 5.1 to 48Vdc Particularly suitable for rugged environment Excellent surge and transient protection Compliant with European railway standards EN 50155 and EN 50121-3-2 Designed for 19" DIN-rack systems occupying 3U/4TE but can also be chassis-mounted by means of four screws Fully enclosed in black-coated aluminium case acts as a heat sink and an RFI shield, ideal for cold wall mounting Conformal coating provides very high levels of protection against humidity and conductive dust Hot plug and current share for redundant applications Low inrush current, hot swappable. 48V input products complaint with telecoms standard ETS 300132-2 Features include wide trim range, output OK signal and inhibit Dimensions: H111 x W20 x L172 mm Weight: 480g Minimum isolation voltage: 4.2 kV. Regulation output 2. Vo2 depends upon the load distribution: If each output is loaded with at least 10% of Io nom, the deviation of Vo2 remains within ±5% of Vo nom. The figures 12, 13 and 14 on page 14 of the attached datasheet explain the regulation with different load distributions up to the current limit. If Io1 = Io2 or the two outputs are connected in series, the deviation of Vo2 remains within ±1% of the value of Vo nom, provided that the load is at least Io min.
