| WR-XC and WR-MP SERIES Single and dual output * * * * * * * * 2:1 input range WR-XC UL approved Efficiency to 86% Isolated outputs Six sided shield Remote on/off control on XC models 100kHz switching frequency Two package sizes available [ 2 YEAR WARRANTY ] The WR series DC/DC converters accept a wide input voltage range of 918VDC, 18-36VDC or 36-72VDC. A 100kHz switching regulator produces operating efficiencies up to 86% at full load and as high as 80% at light load. In the case of duals, full power may be taken from either output. All models will tolerate a short circuit between positive and negative outputs or between either output and common indefinitely. Load regulation of 1%, line regulation of 0.2%, Pi input filtering and remote on/off control (XC package only) which can be improvised as an undervoltage shutdown signal, are featured on all models. Six-sided continuous EMI/RFI shielding is provided in both XC and MP packages. The operating temperature range is -25C to +71C convection cooled, with no derating required.

Standard specifications are conservative and can be optimised for specific applications. In particular, converter start-up at lower than specified temperature, wider input voltage range and output voltage adjustment are all relatively simple modifications to the standard product. Consult factory for details. Fixed frequency design provides for easier input filtering and better noise performance. In many cases, the isolation specification may be upgraded. Consult factory for details. XC case only (single output models): to trim up connect pin 4 to pin 7 through a 10k resistor, or pin 4 to pin 6 to trim down. MTBF figures are based on actual product performance.
