A low ac-impedance input source is recommended. If the source inductance is more than a few μH, we advise 220μF electrolytic capacitor (ESR < 0.7 Ω at 100 kHz) mounted close to the input of the module to improve the stability. Layout and EMC Considerations Delta’s DC/DC power modules are designed to operate in a wide variety of systems and applications. For design assistance with EMC compliance and related PWB layout issues, please contact Delta’s technical support team. An external input filter module is available for easier EMC compliance design. Below is the reference design for an input filter tested with H36SA54003 to meet class B in CISSPR 22. Schematic and Components List C1=C2= 4.4uF ceramic capacitor C3=0.1uF ceramic capacitor CY1=CY2=CY3=CY4=10nF C4=100uF Electrolytic capacitor L1=L2=0.473mH common chock(Pulse P0502) The power module must be installed in compliance with the spacing and separation requirements of the end-user’s safety agency standard, i.e., UL60950-1, CSA C22.2 NO. 60950-1 2nd and IEC 60950-1 2nd : 2005 and EN 60950-1 2nd: 2006+A11+A1: 2010, if the system in which the power module is to be used must meet safety agency requirements. Basic insulation based on 75 Vdc input is provided between the input and output of the module for the purpose of applying insulation requirements when the input to this DC-to-DC converter is identified as TNV-2 or SELV. An additional evaluation is needed if the source is other than TNV-2 or SELV. When the input source is SELV circuit, the power module meets SELV (safety extra-low voltage) requirements. If the input source is a hazardous voltage which is greater than 60 Vdc and less than or equal to 75 Vdc, for the module’s output to meet SELV requirements, all of the following must be met: The input source must be insulated from the ac mains by reinforced or double insulation. The input terminals of the module are not operator accessible. A SELV reliability test is conducted on the system where the module is used, in combination with the module, to ensure that under a single fault, hazardous voltage does not appear at the module’s output. When installed into a Class II equipment (without grounding), spacing consideration should be given to the end-use installation, as the spacing between the module and mounting surface have not been evaluated. The power module has extra-low voltage (ELV) outputs when all inputs are ELV. Test Result:Vin=48V,Io=3A dBμV 80.0 Limits 55022MQP 55022MAV 70.0 60.0 50.0 40.0 Transducer 8130 Traces PK+ AV 30.0 20.0 10.0 0.0 150 kHz 1 MHz 10 MHz 30 MHz This power module is not internally fused. To achieve optimum safety and system protection, an input line fuse is highly recommended. The safety agencies require a normal-blow fuse with 30A maximum rating to be installed in the ungrounded lead. A lower rated fuse can be used based on the maximum inrush transient energy and maximum input current. Soldering and Cleaning Considerations Post solder cleaning is usually the final board assembly process before the board or system undergoes electrical testing. Inadequate cleaning and/or drying may lower the reliability of a power module and severely affect the Blue Line is quasi peak mode;green line is average mode. DS_H36SA54003_08062015 E-mail: [email protected] http://www.deltaww.com/dcdc P7 reliability of a power module and severely affect the finished circuit board assembly test. Adequate cleaning and/or drying is especially important for un-encapsulated and/or open frame type power modules. For assistance on appropriate soldering and cleaning procedures, please contact Delta’s technical support team. Vi(+) Vo(+) Sense(+) ON/OFF trim Rload Sense(-) Vi(-) Vo(-) FEATURES DESCRIPTIONS Over-Current Protection Figure 16: Remote on/off implementation The modules include an internal output over-current protection circuit, which will endure current limiting for an unlimited duration during output overload. If the output current exceeds the OCP set point, the modules will shut down (hiccup mode). The modules will try to restart after shutdown. If the overload condition still exists, the module will shut down again. This restart trial will continue until the overload condition is corrected. Output Voltage Adjustment (TRIM) To increase or decrease the output voltage set point, connect an external resistor between the TRIM pin and the Vout+ or Vout-. The TRIM pin should be left open if this feature is not used. Over-Voltage Protection The modules include an internal output over-voltage protection circuit, which monitors the voltage on the output terminals. If this voltage exceeds the over-voltage set point, the protection circuit will constrain the max duty cycle to limit the output voltage, if the output voltage continuously increases the modules will shut down, and then restart after a hiccup-time (hiccup mode). Over-Temperature Protection The over-temperature protection consists of circuitry that provides protection from thermal damage. If the temperature exceeds the over-temperature threshold the module will shut down.The module will restart after the temperature is within specification. Figure 17: Circuit configuration for trim-up (increase output voltage) If the external resistor is connected between the TRIM and Vout (+) pins, the output voltage set point increases (Fig. 17). The external resistor value required to obtain a percentage of output voltage change △% is defined as: Rtrim up Vo (100 ) 100 2K 1.24 Remote On/Off Ex. When Trim-up +10% (54V×1.1=59.4V) The remote on/off feature on the module can be either negative or positive logic. Negative logic turns the module on during a logic low and off during a logic high. Positive logic turns the modules on during a logic high and off during a logic low. Rtrim up 54 (100 10) 100 2 467K 1.24 10 10 Remote on/off can be controlled by an external switch between the on/off terminal and the Vi (-) terminal. The switch can be an open collector or open drain. For negative logic if the remote on/off feature is not used, please short the on/off pin to Vi (-). For positive logic if the remote on/off feature is not used, please leave the on/off pin to floating. DS_H36SA54003_08062015 E-mail: [email protected] http://www.deltaww.com/dcdc P8 Output Voltage Adjustment (TRIM) THERMAL CONSIDERATIONS Thermal management is an important part of the system design. To ensure proper, reliable operation, sufficient cooling of the power module is needed over the entire temperature range of the module. Convection cooling is usually the dominant mode of heat transfer. Hence, the choice of equipment to characterize the thermal performance of the power module is a wind tunnel. Thermal Testing Setup Figure 18: Circuit configuration for trim-down (decrease output voltage) If the external resistor is connected between the TRIM and Vout (-), the output voltage set point decreases (Fig. 18). The external resistor value required to obtain a percentage of output voltage change △% is defined as 100 Rtrim down 2K Ex. When Trim-down -10% (54V×0.9=48.6V) 100 Rtrim down 2K 8K 10 Delta’s DC/DC power modules are characterized in heated vertical wind tunnels that simulate the thermal environments encountered in most electronics equipment. This type of equipment commonly uses vertically mounted circuit cards in cabinet racks in which the power modules are mounted. The following figure shows the wind tunnel characterization setup. The power module is mounted on a 185mmX185mm,70μm (2Oz),6 layers test PWB and is vertically positioned within the wind tunnel. The space between the neighboring PWB and the top of the power module is constantly kept at 6.35mm (0.25’’). PWB FANCING PWB MODULE When using remote sense and trim, the output voltage of the module is usually increased, which increases the power output of the module with the same output current. 50.8(2.00") Care should be taken to ensure that the maximum output power of the module remains at or below the maximum rated power. AIR VELOCITY AND AMBIENT TEMPERATURE SURED BELOW THE MODULE AIR FLOW Note: Wind Tunnel Test Setup Figure Dimensions are in millimeters and (Inches) Figure 19: Wind tunnel test setup Thermal Derating Heat can be removed by increasing airflow over the module. To enhance system reliability, the power module should always be operated below the maximum operating temperature. If the temperature exceeds the maximum module temperature, reliability of the unit may be affected.
