DatasheetThe DC-DC converters type 2239.91 and 2239.10 are switched-mode DC voltage converters for industrial applications. They are designed as compact step-up converters and are suitable for DC power systems where a higher output voltage must be generated from a lower input voltage.
The units are designed for wall mounting and provide a rated output power in the range of 48 to 240 W. Thanks to their compact design, they can be integrated into systems, control cabinets or technical installations where space is limited.
Type 2239.91 operates with an input voltage of 11.5 to 14.5 VDC and provides a stabilized output voltage of 19 VDC. The output current is 8 A and limited to 10 A. Type 2239.10 operates with an input voltage of 11 to 14.5 VDC and provides an output voltage of 24 VDC at an output current of 10 A.
Both versions provide fast regulation for load changes from 10 to 100 %. The operating conditions are designed for a temperature range of 0 to 35 °C and a maximum relative humidity of 85 % at 35 °C.
Depending on the version, the units differ in housing design, connections and electrical characteristics. Type 2239.91 uses M6 brass bolts for input and output connections, while type 2239.10 is equipped with 6.3 mm flat connectors. Both units provide IP30 protection rating and protection class II.
