Basic insulation system
The BXA30 series, comprising 9 different models, has been conceived as an
applications-specific range of DC/DC converters, specifically addressing
telecommunications, industrial electronics, test equipment, mobile telecommunications
and distributed power applications. The series offers three wide input voltage ranges, 9-
18VDC and 36-75VDC, and is available in single and dual output versions. Designed to
meet ETSI telecoms interface standards ETS300-132-2 and BTR2511, together with
internal filtering to EN55022 level A, safety approval to EN60950 and UL1950, and
isolation of 1500VDC, the 48VDC models are ideal for telecommunications applications.
The 12V models are particularly suited to industrial, mobile telecom and test equipment
applications, featuring EN61000-4-2, -3, -4, -5 and -6 immunity compliant. Other
features include low output ripple, overvoltage protection, continuous short circuit
protection, remote enable and remote sense.
All specifications are typical at nominal input, full load at 25擄C unless otherwise stated
