FEATURES High efficiency: 90% 3.3V/10A Industry standard 1x2 pinout Size: 33.0 x 24.4 x 8.55mm (1.30x0.96x0.34) SMD and Through-hole versions Fixed frequency operation Input UVLO, OVP OTP and output OCP, OVP (default is auto-restart) Monotonic startup into normal and pre-biased loads 2250V isolation and basic insulation No minimum load required ISO 9001, TL 9000, ISO 14001, QS9000, OHSAS18001 certified manufacturing facility UL/cUL 60950 (US & Canada) recognized Delphi Series S48SP, 35W 1x1 Brick DC/DC Power Modules: 48V in, 3.3V/10A out OPTIONS SMD module available The Delphi Series S48SP, 1x1 Brick, 48V input, single output, Remote On/Off isolated DC/DC converters are the latest offering from a world leader in OTP and Output OVP, OCP mode, power systems technology and manufacturing Delta Electronics, Inc. Auto-restart (default) or latch-up This product family is available in a surface mount or through-hole Short pin lengths package and provides up to 35 watts of power or 10A of output current Encapsulated case optional (3.3V and below) in a new 1x1 form factor (1.30x0.96x0.33). The pinout is compatible with the industry standard 1x2 products. With creative design technology and optimization of component placement, these converters possess outstanding electrical and thermal APPLICATIONS performance, as well as extremely high reliability under highly stressful Optical Transport operating conditions. Typical efficiency of the 3.3V/10A module is better Data Networking than 90%. All modules are fully protected from abnormal input/output Communications, including Wireless and voltage, current, and temperature conditions. traditional Telecom Servers DATASHEET DS S48SP3R310 10252013 TECHNICAL SPECIFICATIONS (T =25C, airflow rate=300 LFM, V =48Vdc, nominal Vout unless otherwise noted.)
