DatasheetThe switched-mode DC-DC converters type 2218.2 to 2218.8 are compact voltage converters for wall mounting. They are suitable for industrial applications, mobile electrical systems and technical installations where a defined output voltage must be supplied from an existing DC input voltage.
The series covers a rated output power range from 60 to 240 W. Depending on the version, nominal input voltages of 24 VDC, 48 VDC or 60 VDC are available. The input voltage ranges are 18 to 28 VDC, 42 to 56 VDC or 50 to 70 VDC depending on the type.
On the output side, versions with 5 VDC, 12 VDC or 24 VDC are available. Depending on the version, the units provide output currents of 5 A, 10 A or 20 A. The output voltage is stabilized and the CV ripple RMS value is 50 mV.
The converters are short-circuit protected and do not provide galvanic isolation between input and output. The settling time for load changes from 10 to 100 % is 1.5 ms. Depending on the type, cooling is provided by convection or by a fan.
Most versions provide IP30 protection rating and protection class III. Type 2218.8 is equipped with an aluminium die-cast enclosure and provides IP65 protection. Electrical connection is made via 6.3 mm flat connectors, M6 bolts or cables, depending on the type.
