The C300 and B300 series 150W dc/dc converters, ac/dc power supplies and battery chargers offer packaging, mounting and input choices. The C300 dc/dc product line includes seven dc input ranges: 10-16 V, 18-36 V, 36-75 V, 45-90 V, 80-160 V, 160-320 V and 320-380 V with 10 single-output voltages ranging from 5 Vdc to 220 Vdc. The C300 ac/dc series offers the same output voltage ranges from a choice of 110 Vac, 230 Vac or 115-230 Vac inputs. The BP200 series battery chargers provide output voltages ranging from 12 Vdc to 290 Vdc. Requests for custom output voltages can be accommodated.
Efficiencies range from 70-90% and all models feature tight line and load regulation. Remote sense, comprehensive overvoltage and overload protection circuitry are standard. Options include dc input reverse-polarity protection, redundant operation, remote on/off and temperature-compensated charging voltage.
Units use industrial-grade components that achieving an operating temperature range of -20 to 75 C; extended temperature to -40 C is optional. EN55022 Class-A EMI is specified (optional Class B), as well as immunity to EN61000-4-2, EN61000-4-4 and EN61000-4-5 Level 3 standards. The series offers four mechanical configurations of a 19-inch Eurocard mounting, wall mounting, chassis-mount packaging or DIN rail mounting package.
