DESCRIPTION

The PQU650M-xxP Series products are rated at 650W employing a “U” channel construction that operates with natural or forced convection airflow. The PQU650M series is a 6”x 4” format capable of providing a continuous 650W1 output, with a constant current overload characteristic, and 800W “power boost” at output start4 to support transient system loads. The compact form factor offers an impressive 450W of natural convection cooled power at +50°C, whilst 650W is available using either external (system) airflow or via the optional cover assembly with integrated 80mm low profile fan. Provision of an adjustable Main output, in addition to Auxiliary/Standby and fan outputs, will enable this technically superior solution to be deployed in the medical market sector, where applied part Type B or BF# deployment is required, complemented by medical standard safety certification. All variants are provided with header style connectors, for AC source, DC output and signal/fan interfaces, and incorporate a droop current sharing characteristic for parallel/redundant operation. #Applies to the Main V1 output only.

Curves generated for the PQU650M variants by subjecting output to an incremental (constant resistance load, equivalent to 1Ad c increments (above full load). 2. The resultant curve shows the current limited to a constant “brick wall” shown by the blue portion of curve. 3. If the load current is further incremented the output will enter “hiccup” (recycling on/off; shown by the red dashed curve) commencing when the output voltage falls to ~75% of the nominal set point. 4. If the overload current is maintained above maximum load for an extended period the “hiccup” operation will continue indefini tely while the overload persists. In the event that the overload is maintained just below that where “hiccup” operation is initiated then, dependent on the prevailing operating conditions, the power module may enter thermal protection. 5. Each time the output recovers from hiccup the output power will be capable of 800W peak to provide additional power to ensure that the transient load is delivered.

650W; 4" x 6"“U” Channel; AC-DC Power Supply Converter https://www.murata.com/ products/power Subject to Change Without Notice PQU650M.A03 Page 4 of 12 CURRENT SHARING OPTION Model Number Description All PQU650M; Refer to ACAN-107 for additional details Main output current share is achieved using the “droop” method. Nominal output voltage is achieved at 50% load; the output voltage increases/decreases (approximately ±3% of nominal voltage) with decreasing/increasing ( respectively) load current. This regulation window does not include the additional tolerance due to line, and temperature, long term stability. Startup of parallel power supplies is not internally synchronized. No more than 800W combined power is allowed at start-up. To account for±10% full load current sharing accuracy, and the reduction in full load output voltage due to 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 connected to the common load. External ORING protection is recommended (see Application notes, ACAN-105 for additional details); Aux (V2) outputs can be tied together for redundancy but total combined output power must not exceed 2.5W; external ORing devices are recommended to preserve redundancy. It is not recommended that the 12V Fan (V3) outputs are connected in parallel since these outputs are only semi regulated.

STATUS AND CONTROL SIGNALS Parameter Models Conditions PS_ON Connector J3 Pin 3 All Models (Except if separately noted) This pin can be left unterminated (or alternatively pulled high to +5V_AUX; Connector J3 Pin 1) to (enable) turn on the main output. The +5V_AUX output is independent of the PS_ON signal, and comes up automatically when the input AC or input DC voltage is applied (within their respective specified operating ranges). If it is desired to turn off the Main Output (during normal operation) then this pin can be pulled “low” (sink current ≥2mA) to +5V_AUX_RTN. PWOK Connector J3 Pin 2 All Models The PWOK is a combined digital signal that signifies the status of the Main V1 output. It changes state due to loss of the incoming AC source and any condition that causes the Main V1 DC output shutdown (UVP, OCP, OTP protection). The output is via an open drain CMOS buffer (that has a 10K pull up resistor to an internal +5Vdc rail) that transitions high 15-25ms after the main output is within regulation; it transitions low at least 1msec before loss of regulation.

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 EN550 32 class B radiated emissions with a metal enclosure with grounded base plate. See PQU-COVER for details - testing was based on adding a toroid (4 turns of both main output wires wound as common mode choke on FAIR -RITE#5961002701 torroid. Radiated emission results vary with system enclosure and cable routing paths. A minimum 10% load current is required, on the main output.

The product is designed to provide 450W using natural convection cooling when mounted with un-obstructed convection current airflow flow at up to +50°C local ambient temperature. At elevated temperatures 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 diverse orientations; See ACAN-106 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 critical componenets exceed their safe and reliable thermal limits. Additonally, life expectantcy of the power supply is inversely proportional to the case temperature of electrolytic capacitors. The designer of the system in which this power module is deployed should consider this relationship to ensure optium product life. The following charts are life predications based on 80% of full load capability (and illustrate this relationship). The PQU650M Series will also benefit from the provision of forced convection cooling airflow either generated by an external host system fan or from the integral fan provided in the optional PQU650M-F-COVER assembly. A dedicated 12V Fan (V3) output is provided that can be used to power an external (system) fan. This shall enable operation to the full capability of 650W at +50°C local ambient (forced convection cooling air) temperature . Please refer to ACAN-106 for additonal details DERATNG CURVES Output Thermal Derating Derating with Input Line

• The PQU650M will reliably provide 450W cooled by natural convection with no derating for AC line at a local ambient temperature of +50°C; except for PQU650M -12P that is derated to 400W at +50°C.
• It is also capable of providing 300W at operation up to +70°C.
• The PQU650M shall provide 650W of power with a minimum recommended airflow of 40mm); this equates to circa 13CFM/ 6.14 litre /s) via an external (system fan) or when provided with the PQU650M-F-COVER assembly with integral (top) mounted fan. No derating with input line voltage for convection or forced cooling airflow s for all series variants except for PQU650M-12P that derates to 400W when convection cooled.

Since each output has an identical “droop” share characteristic then each output will intrinsically share the total load curr ent. See ACAN-107for more details. It is recommended that for redundant (critical) applications that external isolation devices (diodes or MOSFETS) are employed . See ACAN-105 for more details
