PQC250-XX-DXX Model Number Description Main Output current share is achieved using ?the droop method?. 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.

PQC250-XX-DXX Model Number Description Main Output current share is achieved using ?the droop method?. 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.
