BXA30

BXA30 Series DC/DC CONVERTERS Triple output 30W Wide Input DC/DC Converters 1 • Pin-compatible with BXA15 series • Designed to meet telecom power supply interface standard ETS300-132-2 • UL, CSA and VDE approvals • VDE0878 and EN55022 conducted emissions level A • EN61000-4-2, -3, -4, -5, -6 immunity compliant • Fixed frequency operation at 350kHz • MTBF in excess of 7,005,000 hours (demonstrated) • Basic insulation system The BXA30 triple output Series, comprising 2 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 two wide input voltage ranges, 18-36VDC and 36-75VDC. 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 basic insulation of 1500VDC, the 48VDC model is ideal for telecommunications applications. The 24V model is 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, short circuit protection, remote enable. 2 YEAR WARRANTY All specifications are typical at nominal input, full load at 25°C unless otherwise stated SPECIFICATIONS OUTPUT SPECIFICATIONS Output power Line regulation (See Note 1) Load regulation (See Note 2) Ripple and noise (20MHz bandwidth) Main output Auxiliary output Main output Auxiliary output Main output Auxiliary outputs Temperature coefficient Overvoltage protection Short circuit protection Transient response Voltage accuracy Load cross regulation Transient, all outputs 30W ±0.5% ±2.0% ±1.0% ±3.0% 75mV pk-pk 15mV rms 100mV pk-pk 20mV rms ±0.02%/°C 135% Vout init.
