A low ac-impedance input source is recommended. If the source inductance is more than a few μH, we advise 150μF electrolytic capacitor (ESR < 0.7 Ω at 100 kHz) mounted close to the input of the module to improve the stability. dBμV 80.0 Limits 55022MAV 55022MQP 70.0 60.0 50.0 40.0 Layout and EMC Considerations Transducer 8130 Traces PK+ AV 30.0 Delta’s DC/DC power modules are designed to operate in a wide variety of systems and applications.

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 110 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. 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 10A 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 FEATURES DESCRIPTIONS Over-Current Protection 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, and will try to restart after shutdown(hiccup mode). If the overload condition still exists, the module will shut down again. This restart trial will continue until the overload condition is corrected. 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. Remote On/Off 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. 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. 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 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.

The TRIM pin should be left open if this feature is not used. For trim down, the external resistor value required to obtain a percentage of output voltage change △% is defined as: 10 *Vnom * (1 ) Rtrim down K 15 15 * (1 Ex. When Trim-down -10% (15V×0.9=13.5V) 10 *15 * 0.9 Rtrim down K 90K 15 15 * 0.9 For trim up, the external resistor value required to obtain a percentage output voltage change △% is defined as: Rtrim up Vnom * 5(1 ) K Vnom *（1 ） 6 * 2.5 Ex. When Trim-up +10% (15V×1.1=16.5V) Rtrim up 15 5 (1 0.1） 55K 15 *（1 0.1） 6 * 2.5 The output voltage can be increased by both the remote sense and the trim, however the maximum increase is the larger of either the remote sense or the trim, not the sum of both. 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 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 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 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. AIR VELOCITY AND AMBIENT TEMPERATURE SURED BELOW THE MODULE 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. MODULE AIR FLOW Note: Wind Tunnel Test Setup Figure Dimensions are in millimeters and (Inches) Figure 15: 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.
