electrical shock ? energy hazards ? fire ? mechanical and heat hazards ? radiation hazards ? chemical hazards on-board dc/dc converters and dc/dc regulators are defined as component power supplies. as components they cannot fully comply with the provisions of any safety requirements without ?con ditions of acceptability?. clearance between conductors and between conductive parts of the component powe r supply and conductors on the board in the final product must meet the applicable safety requirements. certain conditions of acceptability apply for component power supp lies with limited stand-off (see mechanical information for further information). it is the responsibility of the installer to ensure that the final product housing these components complies with the requirements of all applicable safety standards and regulations for the final product. component power supplies for general use should comply with the requirements in iec 60950-1, en 60950-1 and ul 60950-1 safety of information technology equipment. there are other more product related standards, e.g. ieee 802.3 csma/cd (ethernet) access method , and ets-300132-2 power supply interface at the input to telecommunications equipment, operated by direct current (dc) , but all of these standards are based on iec/en/ul 60950-1 with regards to safety. ericsson power modules dc/dc converters and dc/dc regulators are ul 60950-1 recognized and certified in accordance with en 60950-1. the flammability rating for all construction parts of the products meet requirements for v-0 class material according to iec 60695-11-10, fire hazard testing, test flames ? 50 w horizontal and vertical flame test methods. the products should be installed in the end-use equipment, in accordance with the requirements of the ultimate application. normally the output of the dc/dc converter is considered as selv (safety extra low voltage) and the input source must be isolated by minimum double or reinforced insulation from the primary circuit (ac mains) in accordance with iec/en/ul 60950-1. isolated dc/dc converters it is recommended that a slow blow fuse is to be used at the input of each dc/dc converter. if an input filter is used in the circuit the fuse should be placed in front of the input filter. in the rare event of a component problem that imposes a short circuit on the input source, this fuse will provide the following functions: ? isolate the fault from the input power source so as not to affect the operation of other parts of the system. ? protect the distribution wiring from excessive current and power loss thus preventing hazardous overheating. the galvanic isolation is verified in an electric strength test. the test voltage (v iso ) between input and output is 1500 vdc or 2250 vdc (refer to product specification). 24 v dc systems the input voltage to the dc/dc converter is selv (safety extra low voltage) and the output remains selv under normal and abnormal operating conditions. 48 and 60 v dc systems if the input voltage to the dc/dc converter is 75 vdc or less, then the output remains selv (safety extra low voltage) under normal and abnormal operating conditions. single fault testing in the in put power supply circuit should be performed with the dc/dc converter connected to demonstrate that the input voltage does not exceed 75 vdc. if the input power source circ uit is a dc power system, the source may be treated as a tnv-2 circuit and testing has demonstrated compliance with selv limits in accordance with iec/en/ul60950-1. non-isolated dc/dc regulators the input voltage to the dc/dc regulator is selv (safety extra low voltage) and the output remains selv under normal and abnormal operating conditions. e pkb 4000 series dc/dc converters, input 36-75 v, output 30 a/90 w en/lzt 146 394 r5d october 2013 ?

remote control, which can be ordered by adding the suffix ?p? to the end of the part number. the converter will turn on when the input voltage is applied with the rc pin open. turn off is achieved by connecting the rc pin to the - in. to ensure safe turn off the voltage difference between rc pin and the - in pin shall be less than 1v. the converter will restart automatically when this connection is opened. see design note 021 for detailed information. input and output impedance the impedance of both the input source and the load will interact with the impedance of the dc/dc converter. it is important that the input source has low characteristic impedance. the converters are designed for stable operation without external capacitors connected to the input or output. the performance in some applications can be enhanced by addition of external capacitance as described under external decoupling capacitors. if the input voltage source contains significant inductance, the addition of a 100 f capacitor across the input of the converter will ensure stable operation. the capacitor is not required when powering the dc/dc converter from an input source with an inductance below 10 h. external decoupling capacitors when powering loads with significant dynamic current requirements, the voltage regulation at the point of load can be improved b y addition of decouplin g capacitors at the load. the most effective technique is to locate low esr ceramic and electrolytic capacitors as close to the load as possible, using several parallel capacitors to lower the effective esr. the ceramic capacitors will handle high-frequency dynamic load changes while the electrolytic capacitors are used to handle low frequency dynamic load changes. ceramic capacitors will also reduce any high frequency noise at the load. it is equally important to use low resistance and low inductance pcb layouts and cabling. external decoupling capacitors will become part of the control loop of the dc/dc converter and may affect the stability margins. as a ?rule of thumb?, 100 f/a of output current can be added without any additional analysis. the esr of the capacitors is a very important parameter. power modules guarantee stable operation with a verified esr value of >10 m? across the output connections. for further information please contact your local ericsson power modules representative. output voltage adjust (v adj ) the dc/dc converters have an output voltage adjust pin (v adj ). this pin can be used to adjust the output voltage above or below output voltage initial setting. when increasing the output voltage, the voltage at the output pins (including any remote sense compensation ) must be kept below the threshold of the over volta g e protection, (ovp) to prevent the converter from shutting down. at increased output voltages the maximum power rating of the converter remains the same, and the ma x output current must be decreased correspondingly. to increase the voltage the resistor should be connected between the v adj pin and +sense pin. th e resistor value of the output voltage adjust function is according to information given under the output section for the respective product. to decrease the output voltage, the resistor should be connected between the v adj pin and ?sense pin. e pkb 4000 series dc/dc converters, input 36-75 v, output 30 a/90 w en/lzt 146 394 r5d october 2013 ?
