2 / 20 page  EN/LZT 146 09 R1A © Ericsson Microelectronics AB, June 2000 2 Stress in excess of Absolute Maximum Ratings may cause permanent damage. Absolute MaximumRatings, 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. Environmental Characteristics Characteristics Frequency 10–500 Hz Amplitude 0.75 mm Acceleration 10 g Number of cycles 10 in each axis Vibration (Sinusoidal) IEC 68-2-6 Fc Test procedure & conditions Peak acceleration 200 g Shock duration 3 ms Shock (Half sinus) IEC 68-2-27 Ea Temperature –40°C to +125°C Number of cycles 10 Temperature change IEC 68-2-14 Na Damp heat IEC 68-2-3 Ca Temperature 40°C Duration 56 days Bump (Half sinus) IEC 68-2-29 Eb Peak acceleration 40 g Bump duration 6 ms Number of bumps 1000 in 6 directions Accelerated damp heat IEC 68-2-3 Ca with bias Temperature 85°C Humidity 85% RH Duration 500 hours Safety The PKA 2000 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 PKA power modules are recognized by UL and meet the applicable requirements in UL 1950 Safety of information technology equip- ment, the applicable Canadian safety require- ments and UL 1012 Standard for power sup- plies. The DC/DC power module shall be installed in an end-use equipment and considerations should be given to measuring the case tem- perature to comply with TCmax when in operation. They are intended to be supplied by isolated secondary circuitry and shall be installed in compliance with the require- ments of the ultimate application. If con- nected to a 24 V DC power system reinforced insulation must be provided in the power supply that isolates the input from the ac mains. The isolation in the DC/DC power module is an operational insulation in accord- ance with EN 60 950. 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 con- nection to mating connectors of internal wiring inside the end-use equipment. The isolation voltage is a galvanic isolation and is verified in an electric strength test. Test voltage (VISO) between input and output is 500 V dc. The capacitor between input and output has a value of 10 nF and the leakage current is less than 1 mA @ 26 V dc. Flammability ratings of the terminal support and internal plastic construction details meets UL 94V-0. General 1) Corresponding ambient temp. range (TA) at full output power is –45 to +85 °C.
