Nominal output voltage is achieved at 50% load and output voltage increases/decreases approximately ±3% of nominal voltage. This regulation window does not include the additional tolerance due to line, temperature, long term stability etc. PQC250-XX-Dxx Startup of parallel power supplies is not internally synchronized. If more than 250W combined power is needed, start-up synchronization must be provided Refer to ACAN-78 by system using a common PS_ON signal. To account for ±10% full load current sharing accuracy and the reduction in full load output voltage due to for additional droop, available output power must be derated by 15% when units are operated in parallel. Current sharing can be achieved with or without remote sense details connected to the common load. ORing protection is available on the PQC250-xxDRT models (see Application notes, ACAN-78 for additional details); Aux (V2) output can be tied together for redundancy but total combined output power must not exceed 2.5W, external ORing devices are recommended to preserve redundancy.

To comply with safety standards, this plate must be properly grounded to protective earth (see mechanical dimension notes). Pre-compliance testing has shown the stand-alone power supply to comply with EN55022 class B radiated emissions with a metal enclosure with grounded base plate. See PQC-COVER for details - testing was based on adding a toroid, Fair- Rite#5961004901 with five turns of both of the output leads. Radiated emission results vary with system enclosure and cable routing paths. EMI CONSIDE STATUS AND CONTROL SIGNALS Parameter Models Conditions This pin must be pulled low (sink current >2mA) to +5V_AUX_RTN to turn on the main output. The +5V_AUX output is independent of the PS_ON PS_ON All Models signal, and comes up automatically when the input AC or input DC voltage is applied within their specified operating ranges. Open collector logic goes high 40-100ms after the main output is within regulation; it goes low at least 2msecs before loss of regulation. Internal PWR_OK All Models 10K pull up to +5V_Aux is provided. Applications using the PWR_OK signal should maintain a minimum load of 5W on the main output.

Performance derating curves are provided which can be used as a guideline for what can be achieved in a system configuration with controlled airflow at various input voltage conditions. The product is designed to provide 250W using natural convection cooling when mounted horizontally with un-obstructed convection current airflow flow at room temperature. At elevated temperature the power supply data is taken while it is surrounded by a large vented enclosure to minimize forced cross flows inherent in the elevated temperature test. The product is capable of operation when mounted in other orientations; operational/derating curves shall be provided to show the effect of such mounting. See ACAN-77 for additonal details Capacitor case temperature and Mounting Orientation: The power supply can operate in any orientation; however, the power supply contains overtemperature protection that will shut off the output as the temperature of the power supply heatsinks approach the limt specified in the protection table. Additonally, life expectantcy of the power supply is inversely proportional to the case temperature of electrolytic capacitors C25, C25A, C711 & C712. The designer of the system in which this power supply is deployed should consider this relationship to ensure optium product life. The following charts illustrate this relationship: The PQC250 Series will also benefit from the provision of forced cooling airflow (generated by an external host system fan). This will enable operation at potentially higher local surrounding ambient temperatures. Please refer to ACAN-78 for additonal details Derating Curve vs. Temperature (based on horizontal mounting, PTH components facing up, natural convection) Derating curves are provided to indicate operation at varying input voltages with respect to temperature.

Since each output has an identical “droop” share characteristic then each output will intrinsically share the total load current.

This power supply is a component level power supply intended for use in Class I or Class II applications. Secondary ground traces need to be suitably isolated from primary ground traces when used in Class II applications. 2. When the power supply is used in Class II equipment, all ground traces and components connected to the primary side are considered primary for spacing and insulation considerations. 3. Protective bonding conductor from the end product protective earthing terminal must be tied to TB1. For optimum EMI performance, while maintaining Class I safety isolation all 4 mounting holes must be tied to the end product protective earthing terminal. To maintain Class II safety isolation mounting holes MTG1 and MTG2 need to be isolated from protective earth and should use standoffs of non-conductive material. 4. This power supply requires mounting standoffs of minimum 6mm in height. If there is risk of chassis deformation or shorter standoff height is required, an appropriate insulator must be used under the power supply with adequate extension beyond the outline of the power supply. In all cases, the applicable safety standards must be applied to ensure proper creepage and clearance requirements are met. 5. The primary heatsink is considered a live primary circuit, and should not be touched. It is recommended that the primary heatsink be kept at least 6.
