DESCRIPTION

The RUW series is particularly suitable for use

in applications in railway, industry or telecom-

munication where variable input voltages or

high transient voltages are present. With an ultra

wide input voltage range of 16-160VDC, the

RUW series is capable of withstanding surges

from 24,36,48,72, 90 and 110V systems, largely

eliminating the requirement for input protection

circuitry.

Optional features include a Power Fail/DC OK

signal and circuitry to facilitate long hold-up times

with a small external capacitor across ±Vint pins.

RUW15 Series Isolated Ultra-Wide Input DC/DC Converters SAFETY UL 60950 The RUW15 series has been recognised by Underwriters Laboratory (UL) to UL 60950 for reinforced insulation to a working voltage of 250Vrms in maximum temperature as shown in the derating graphs. The RUW15 series of converters are not internally fused so to meet the requirements of UL a 3A anti-surge input line fuse should always be used. File number E151252 applies.

RUW15 Series Isolated Ultra-Wide Input DC/DC Converters APPLICATION NOTES (continued) Power Fail Warning Details A ‘power fail’ signal is available which goes active after the input voltage drops out but before the output loses regulation. Over-temperature and over-voltage monitoring is included which also activates the ‘power fail’ signal.

RUW15 Series Isolated Ultra-Wide Input DC/DC Converters SURGE SUPPRESSION EN50155/RIA12 surge/dip compliance DC/DC power converters connected to the battery voltage or other low voltage source in railway rolling stock commonly have to comply with the requirements of European standard EN 50155:2007. This standard defines a range of nominal battery voltages that may be encountered with possible fluctuations and interruptions. Nominal voltages (Un) are 24V, 48V, 72V, 96V and 110VDC with tolerances of -30/+25%.

RUW15 Series Isolated Ultra-Wide Input DC/DC Converters EMC FILTERING AND SPECTRA FILTERING The module includes a basic level of filtering, sufficient for many applications. Where lower noise levels are desired, filters can easily be added to achieve any required noise performance. A DC/DC converter generates noise in two principle forms: that which is radiated from its body and that conducted on its external connections.
