2 This datasheet covers the details of the IC50X series of power supplies with single output voltage and output power of 250 W, which can be powered directly by the electric rail traction systems (650 VDC and 750 VDC). These DC/DC converters are designed according to EN 50155:2007 for railway applications and are ideal for other demanding environments which require the highest performance and reliability. Output voltages: 24 V, 48 V, 72 V, 110 V. Other voltages on request. Ordering codes: IC501_3, IC503, IC504, IC506_1. The differences between the variants are explained in this datasheet. FEATURES - Wide input voltage range: continuous operation from VDC (wider than required by the standard EN 50163:2004 supply voltages of traction systems, which requires only VDC as permanent voltage range). - High Surge-Robustness: active surge-limiter withstands 3 kv for 20 ms and 4.5 kv falling to kv for 1 ms (10-times longer over-voltage pulse than required by standard EN :2017 Over-voltages and related protection ). No degradation of performance or loss of function during the surge (performance criterion A according to EN :2017). - High efficiency: >89 % over the entire input-voltage range. - Very low dissipation and low component stress during standby-mode: - IC501_3: < VDC input voltage; IC506_1: < VDC input voltage. - Wide temperature range: C (temperature class TX). - Full power (250 W, no derating) over the entire temperature range. - Small and light design: the weight of the unit is only 1.2 kg. - Continuous-overload and short-circuit proof. - Hold-up time >10 ms: complies with class S2 according to EN 50155: Fully compliant with EN 50155:2007 and EN 45545: Very high galvanic isolation between input and output: 3300 VAC. - Field proven technology. - Standard model ex stock. - On request connectors of your choice; individual case style; additional functions as Power Fail signal, etc. Page 2 of

14 INSTALLATION AND OPERATION Warning / Caution! Safety The power supplies should be installed and put into operation only by qualified personnel. Before installing or removing the unit, disconnect the power from the system. The nut on the chassis must be connected to earth permanently (M4 and M5 nuts available on the unit). Servicing Spare Parts Disposal Connecting the Cables Operation of the Unit In case of failures, malfunctions or defects, the converter must be returned to intrexis for analysis and repair. In particular, the converter should be sent to intrexis for analysis if any damage has occurred to the unit (e.g. the unit dropped). Any attempts to open and repair the unit could void the warranty and could expose the operator to hazardous voltages. List and drawings of spare parts are not provided, since the failed units have to be returned to intrexis for analysis and repair. Disused units must be collected separately and disposed at a suitable recycling facility. Ensure that proper wires are used according to the input and output current specifications. Prepare the cables according to the specifications of the particular connector used. Ensure correct connection according to the connector pinout (pin 1 is shown in the section 'Mechanical Characteristics & Mounting'). The input cables must be connected to the screw terminals (+V, -V) with suitable hardware (2x M4 ring-terminals, washers and screws, not provided). Once the input power is applied, the output voltage is enabled, unless the External ON/OFF signal is disabling the converter (OFF-state). A green LED provides a visual indication that the output voltage is ok. Page 14 of
