EP2660-9R

These extremely compact DC-DC converters incorporate all necessary input and output filters, signalling and protection features, which are required in the majority of applications. The converters provide important advantages, such as flexible output power through primary-side current limitation, extremely high efficiency, excellent reliability, very low ripple and RFI noise levels, full input-to-output isolation, negligible inrush current, soft start, over temperature protection and input over- and under voltage lockout.The converters are particularly suitable for rugged environments, such as railway applications. They have been designed in accordance with the European railway standards EN 50155 and EN 50121-3-2. All printed circuit boards are coated with a protective lacquer. The converter inputs are protected against surges and transients occurring on the source lines and cover a total input voltage range from 16 to 150 VDC with five different types. The outputs are continuously open- and short-circuit proof.Full system flexibility and n+1 redundant operating mode are possible due to series or parallel connection capabilities of the outputs under the specified conditions. When several converters (with 3.3 and 5.1 V outputs) are connected in parallel, the T option allows for a single-wire connection between the converters to ensure good current sharing.
