i1C

The i1C series are non-isolated buck-boost DC-DC converters that delivers up to 200W in a compact and familiar industry standard 1 x 1 inch footprint. Operating from either a 9-36V or 18-75V input, it comes with a wide adjustable output of 9.6 to 28V that can support multiple system load voltages, minimizing part number variations. Encased in a 5-sided metal case that supports -40 to 120°C case temperature operation along with its remarkable 98% efficiency, the i1C series provides a higher power migration path in applications where space is at a premium.

CN-B

The rugged 50-150W quarter and 200-300W half brick CN-B110 series of isolated DC-DC converters operate from a very wide 43 to 160V input. With an input to baseplate isolation of 2,500Vac and 3,000Vac input to output, the series is designed for use on 72V or 110V nominal input rail power systems. In addition, the baseplate cooled modules meet the rolling stock IEC 61373 Category 1, Class B shock / vibration standards and are designed to meet EN 45545-2 (Fire protection on railway vehicles). The CN200B and CN300B models features active current share for parallel or redundant operation, remote sense, remote on/off, output voltage adjustment and a power good signal. Also available are optional auxiliary voltages, replacing the power good signal on the 200-300W models and the -sense on the 50-150W models.

PY

The PY family are pcb-mountable DC-DC converters in various package sizes with output powers ranging from 20 to 200W.

The family's ultra-wide input voltage range (from 8.5 to 160V - model dependent) enables a single converter to be used in multiple applications. With its approval to EN 50155, it is also suitable for railway applications.

Its high efficiency results in low heat generation and the potted construction promises high shock and vibration performance which together with the wide operating temperature range make these devices suitable for nearly any situation.

Additionally, heat sink kits are available to simplify integration when contact cooling is not possible.

RGC

The rugged RGC non-isolated DC-DC buck-boost converters are encapsulated in a five-sided aluminium case and rated for up to 115˚C operation. The modules have the industry standard 1/16th brick pin-out, are qualified to MIL-STD-810G (shock and vibration) and designed for fan-less, conduction cooled applications. The series accepts a wide input range to support multiple DC bus and battery voltages. Standard and optional features include remote on/off, remote sense, power good, frequency synchronization and output current monitoring, making the modules a truly versatile power solution. The wide output adjustment range allows one model to be used in multiple positions, assisting inventory and part number reduction.
