DatasheetThe switched-mode DC-DC converters type 2238.0, 2238.6 and 2238.61 are compact DC voltage converters for wall mounting. The units operate as voltage doublers and convert a low input voltage of 5.5 to 8 VDC or 5.8 to 8 VDC into an output voltage of 12 VDC.
The converters are suitable for industrial applications, mobile power supply systems and technical installations where a 12 V supply is required from a lower DC voltage source. Depending on the version, output currents of 10 A, 20 A or 30 A are available. The series therefore covers a rated output power of up to 360 W.
Type 2238.0 provides an output current of 10 A and is cooled by convection. The higher-power versions 2238.6 and 2238.61 are equipped with a switched fan. Type 2238.61 additionally features an LED operating indicator for the output voltage Ua.
The units are short-circuit protected and do not provide galvanic isolation between input and output. The negative pole is connected to the housing. Shutdown at overtemperature is provided. The settling time for load changes from 10 to 100 % is 1.5 ms.
The electrical connections differ depending on the type. Type 2238.0 uses 6.3 mm flat connectors, type 2238.6 uses VDFK 4 terminals and type 2238.61 uses M10 brass bolts. All versions provide IP30 protection rating and protection class III.
