PKN 4000 I
50 W DC/ DC power module 48 V input series
· Regulated single and dual outputs · Efficiency >90% (3.3V) from 30% to full load · Low profile 8.5 mm (0.335 in.) · 1,500 Vdc isolation voltage · MTBF >200 years at +75°C case temperature · Full power up to +80°C ambient at 1 m/s airflow · Complete, no extra filters or heatsinks required
The PKN 4000 I series of DC/DC power modules are intended to be used as distributed power sources in decentralized 48/60 V DC power systems. The PKN series use a ceramic substrate with thickfilm technology and a high degree of silicon integration. That together with the electrical design using synchronous rectification gives good thermal management, high reliability and high efficiency. The high efficiency, makes it possible to operate over a wide temperature range without a heatsink. At forced convection cooling >200 lfm (1 m/s), the PKN units can deliver full
power up to +80°C ambient temperature. The high reliability and the low profile of the PKN series makes them particularly suited for Information Technology and Telecom (IT&T) applications with board spacing down to 15 mm (0.6 in.). These products are manufactured using highly automated manufacturing lines with a world-class quality commitment and a five-year warranty. Ericsson Microelectronics AB has been an ISO 9001 certified supplier since 1991. For a complete product program please reference the back cover.

Safety
The PKN 4000 I Series DC/DC power modules are designed in accordance with EN 60 950 Safety of information technology equipment including electrical business equipment, and certified by SEMKO. The isolation is an operational insulation in accordance with EN 60 950. The PKN DC/DC power modules are recognized by UL and meet the applicable requirements in UL 1950 Safety of information technology equipment, the applicable Canadian safety requirements and UL 1012 Standard for power supplies. The DC/DC power module shall be installed in an end-use equipment and is intended to be supplied by isolated secondary circuitry and shall be installed in compliance with the requirements of the ultimate application. When the supply to the DC/DC power module meets all the requirements for SELV (<60Vdc), the output is considered to remain within SELV limits (level 3). If connected to a 60 V DC power system reinforced insulation must be provided in the power supply that isolates the input from the ac mains. Single fault testing in the power supply must be performed in combination with the DC/DC power module to demonstrate that the output meets the requirement for SELV. One pole of the input and one pole of the output is to be grounded or both are to be kept floating. The terminal pins are only intended for connection to mating connectors of internal wiring inside the end-use equipment. These DC/DC power modules may be used in telephone equipment in accordance with paragraph 34 A.1 of UL 1459 (Standard for Telephone Equipment, second edition). The isolation voltage is a galvanic isolation and is verified in an electric strength test. Test voltage between input and output is 1500 V dc for 60 s. In production the test duration may be decreased to 1 s. The capacitor between input and output has a value of 4.7 nF and the leakage current is less than 1mA @ 50 Vdc. Flammability ratings of the terminal support and internal plastic construction details meets UL 94V-0.
Note: 1) The input voltage range 36...75 V meets the requirements in the European Telecom Standard prETS 300 132-2 for Normal input voltage range in 48 V and 60 V DC power systems, 40.5...57.0 V and 50.0...72.0 V respectively.
Stress in excess of Absolute Maximum Ratings may cause permanent damage. Absolute Maximum Ratings, sometimes referred to as no destruction limits, are normally tested with one parameter at a time exceeding the limits of Output data or Electrical Characteristics. If exposed to stress above these limits, function and performance may degrade in an unspecified manner.
