1 If the output voltages are increased above Uo nom through R-input control, option P setting, remote sensing or option T, the output cur-
rents should be reduced accordingly so that
Po nom is not exceeded.
2 Series connection for Uo nom = 24 V, 30 V or 48 V, see: R-Function for different output configurations.
3 Shortest possible wiring for series connection at the connector.
4 See: Output Voltage Regulation of Single Output Units or Double Output Modules with Outputs 1 and 2 Connected in Series.
5 See: Dynamic load regulation of U01 and U02.
6 Negative temperature coefcient (0...–3 mV/cell and K) available on request.
7 Measured according to IEC/EN 61204 sub clause 3.10 with a probe acc. to annex A of the same standards. (See:Technical Informa-
tion: Measuring and Testing)
