## DESCRIPTION 

PQU1000 is a series of 1000W power supply converters, powered by wide range AC input, and offered in a compact 5" x 8" industry standard format. 1000W[1] continuous output power can be achieved with forced convection, and up to an impressive 800W[3] , at +50°C with natural convection airflow. All variants are provided with constant current overload protection allowing operation with motors, solenoids, and high capacitance loads. Active current sharing supports connection of PQU1000 power modules in either non-redundant parallel, or parallel redundant deployments, whilst maintaining equal current share between modules. 

The adjustable main output, standby/auxiliary, and fan outputs, plus PMBus[TM] Power Management Bus enable this series for deployment across multiple market sectors, complemented by safety certification applicable to medical, audio, video, communication and ITE standards.

1000W 5" x 8" AC-DC “U” Channel Power Supply Converter 

## CONSTANT CURRENT CHARACTERISTICS 

The idealized Constant Current characteristic are as shown in the following curves. This feature enables the PQU1000 to successfully start into application loads exhibiting large inrush current i.e. large capacitive loads, incandescent lamps, motors & solenoids. 

1. Curves generated for the PQU1000 variants by subjecting output to an incremental (constant resistance load, equivalent to 1Adc 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 ~50% of the nominal set point 

4. If the overload current is maintained above maximum load for an extended period, the “hiccup” operation will continue indefinitely 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 

## CURRENT SHARING 

## Model Number Description 

Main output adapts active current sharing. The current sharing signal is connected between sharing units to form an ISHARE signal bus. 

The sharing signal is bi-directional analogue bus and acts as an input and/or an output as the voltage on the signal line controls the current share between sharing units. 

A power supply will respond to a change in this voltage; however, a power supply can also change the voltage depending on the load drawn from it. 

On a single unit the voltage on the pin (and the common ISHARE bus would read approximately 8Vdc at 100% load (module capability). 

For two identical voltage variants sharing the same 100% load this would read approximately 4Vdc for perfect current sharing (i.e. 50% module load capability per unit). 

All PQU1000 Variants Startup of parallel power supplies is not internally synchronized; no more than 1000W combined power is allowed at start-up. To account for±10% full load current sharing accuracy, the 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-127 for additional details). 

The +5V_STANDBY (Aux) V2 outputs cannot be tied together for increased power or redundancy; however, +5V_STANDBY_RTN can be tied together to create a common return for the signals between units that share the Main V1 output. 

It is not recommended that the 12V Fan (V3) outputs are connected in parallel since these outputs are only semi regulated, and only intended to supply an external fan (or that of the PQU1000-FT-COVER integral fan).

## ~~>_>,~~ EMI CONSIDERATIONS 

To comply with safety standards, the input connector must be properly grounded to protective earth (see mechanical dimension notes). 

Pre-compliance testing has shown the stand-alone power supply to comply with EN55032 class A radiated emissions; testing was based on adding a toroid (4 turns of both main output wires wound as common mode choke on FAIR-RITE#5961002701). 

Radiated emission results vary with system enclosure and cable routing paths. 

A minimum 10% load current is required, on the main output.

1000W 5" x 8" AC-DC “U” Channel Power Supply Converter 

## THERMAL CONSIDERATIONS 

System thermal management is critical to the performance and reliability of the PQU1000 series power supplies. 

The product is designed to provide 800W 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; operational/derating curves shall be provided to show the effect of such mounting. See ACAN-128 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. 

The life expectancy 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) that illustrate this relationship. 

The PQU1000 Series will also benefit from the provision of forced convection cooling airflow either generated by an external host system fan or by a fan integral to the PQU1000-FT COVER assembly. 

A dedicated 12V Fan (V3) output is provided that can be used to power an external (system) fan, or that of the PQU1000-FT-COVER. This shall enable operation to the full capability of 1000W at +50°C local ambient (forced convection cooling air) temperature. Please refer to ACAN-TBA for additonal details. 

NB: The above curves are based on generic predicted life. 

## DERATNG CURVES Thermal; Convection “U” Channel Thermal; Top Mounted Fan Convection Cooled 

- The PQU1000 will reliably provide 750W cooled by natural convection at 90Vac input, at a local ambient temperature of +50C 

   - No derating with input line voltage for convection or forced convection cooling airflow, for all series variants when cooled with top (cover) mounted fan 

- Slight derating is applied with temperature from +45°C operation, linearly derating to 500W at +70°C

## CONNECTION DIAGRAM 

Note: For parallel (current share) operation it is required to connect the sharing power supplies in parallel (+DC out connected together, and DC out Return connected together on sharing power supplies. Since each output has an identical “droop” share characteristic then each output will intrinsically share the total load current. See ACAN-127 for more details. It is recommended that for redundant (critical) applications that external isolation devices (diodes or MOSFETS) are employed.

3. 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 4mm from chassis/ground and 8mm from secondary (SELV) circuitry. In all cases, the applicable safety standards must be applied to ensure proper creepage and clearance requirements are met 

4. This product is subject to the following operating requirements and the Life and Safety Critical Application Sales Policy: https://www.murataps.com/requirements/ 

5. The power supply has been evaluated for 5000m altitude and tropical climatic conditions for China 

6. Double pole/neutral input source fusing is used; the product label is annotated accordingly 

7. If the product is used with the PQU1000 cover assemblies. the relevant safety creepage and clearance requirements are preserved when the PQU1000 if so installed 

8. For all deployment where installed chassis mounting screws are used, the End User should ensure that the screw does not  protrude by more than two (2) threads through the captive PEM mounted in the “U” channel
