Description of Options Railway Applications The Q Series converters have been designed by observing the Option P: Output Voltage Adjustment railway standards EN 50155, EN 50121-3-2, and EN 50121-4. Option P provides a built-in multi-turn potentiometer, which All boards are coated with a protective lacquer. allows an output voltage adjustment of ±10% of V . The o nom The converters comply with class S1 of the fire protection potentiometer is accessible through a hole in the front cover. standard E DIN 5510-2 (Oct. 2007). With double-output models, both outputs are affected by the potentiometer. If different converters are parallel-connected, Isolation and Protective Earth their individual output voltage should be set within a tolerance The test of the resistance of the protective earthing circuit of ±1%.

Power-One will not honor any warranty claims resulting from electric strength field tests. Option -7: Temperature Range Option -7 designates converters with an operational ambient Safety of Operator-Accessible Output Circuits temperature range of –25 to 71 °C. Not for new designs. If the output circuit of a DC-DC converter is operator- accessible, it shall be an SELV circuit according to IEC 60950.
