BXA30-48S3V3/8-F

BXA30 Series Single and dual output DC/DC CONVERTERS 30W Wide Input DC/DC Converters 1 • Designed to meet telecom power supply interface standard ETS300-132-2 • UL, VDE and CSA safety 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 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, 918VDC 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. 2 YEAR WARRANTY SPECIFICATIONS All specifications are typical at nominal input, full load at 25°C unless otherwise stated OUTPUT SPECIFICATIONS EMC CHARACTERISTICS Voltage adjustability Singles Line regulation LL to HL (single/dual) ±0.2%/±0.4% Load regulation FL to NL (single/dual) ±0.2%/±0.4% Ripple and noise (20MHz bandwidth) 3.3V 5.0V All others All models 60mV pk-pk 50mV pk-pk 100mV pk-pk 20mV rms Temperature coefficient ±0.02%/°C Overvoltage protection Transient Short circuit protection Singles Duals (single short) Duals (dual short) Transient response ±10% 135% Vout Continuous (See BXA15/30 Design Note 100) Continuous 25% to 100% load 4.0% Voltage accuracy Load cross regulation ±1.5% Dual output 30% to 100% output variation 3.0% INPUT SPECIFICATIONS Input voltage range Remote ON/OFF Logic compatibility ON OFF Radiated emissions ESD air ESD contact Surge Fast transients Radiated immunity Conducted immunity EN55022, FCC part 15 (Note 4) Level A EN55022, FCC part 15 (Note 5) Level B VDE0878 (Note 4) (48V) Level A EN55022, FCC part 15 Level A EN61000-4-2, level 3 Perf. criteria 2 EN61000-4-2, level 4 Perf. criteria 2 EN61000-4-5, level 3 Perf. criteria 2 EN61000-4-4, level 3 Perf. criteria 2 EN61000-4-3, level 3 Perf. criteria 2 EN61000-4-6, level 3 Perf. criteria 2 GENERAL SPECIFICATIONS Efficiency See table Isolation voltage Basic insulation Input/output input/case, 48V models Switching frequency Fixed 1500VDC 1500VDC 350kHz Approvals and standards (See Note 12) VDE0805, EN60950 IEC950, UL1950 CSA C22.2 No. 950 Case material Aluminum substrate with plastic case Material flammability 12Vin nominal 48Vin nominal Reverse voltage protection (See Note 7) Max. input rise and fall time Conducted emissions 9 to 18VDC 36 to 75VDC Yes UL94V-0 Weight MTBF (See Note 9) 120g (4.24oz) Demonstrated @ 25°C 7,005,000 hours ENVIRONMENTAL SPECIFICATIONS 48V 5V/ms ETS300-132 CMOS/TTL Open circuit
