Schaefer: New Converters, Chargers
Ashland, MA — Schaefer, Inc. has introduced the C300 and B300 Series of 150W DC/DC converters, AC/DC power supplies, and battery chargers. The C300 DC/DC product line has 7 DC input ranges of 10-16V, 18-36V, 36-75V, 45-90V, 80-160V, 160-320V, and 320-380V with 10 single output voltages ranging from 5VDC to 220VDC. The C300 AC/DC Series offers the same range of output voltages from a choice of 110VAC, 230VAC, or 115-230VAC inputs.

The BP200 Series of battery chargers provides output voltages ranging from 12VDC to 290VDC. Requests for custom output voltages are easily accommodated.

Efficiencies range from 70-90 percent and all models provide tight line and load regulation. Remote sense, as well as comprehensive overvoltage and overload protection circuitry is standard. Available options include DC input reverse polarity protection, redundant operation, remote on/off, and temperature compensated charging voltage.

Units utilize industrial grade components, 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.

Compact in size (as small as 6.85 x 3.26 x 4.29-in.) this Series offers four mechanical configurations of a 19-in. Eurocard mounting, wall mounting, chassis mount packaging, or a DIN rail mount package, making them especially suited for a variety of applications including locomotive controls and communications equipment, telecommunication systems, process control systems, and power stations.
