An Advance International Group Company
INTRODUCTION The VWF350 series of switch mode power supplies in the Kestrel family offers 3, 4 or 5 fully regulated dc outputs from a very wide range, power factor corrected, ac input. The 350 watt continuous output power rating is complemented by a 500 watt surge capability. This allows output 2 to support a 200% surge current, ideal for high peak surge current applications such as powering disk drives. Cooling is by integral fan and thermal protection is provided for maximum reliability. An extensive range of output voltage combinations is available to meet the diverse requirements of modern electronic systems. For example, mixed 3.3V and 5V systems are readily supported by the Kestrel family. All outputs, with the exception of low current output 5, have remote sense capability for accurate voltage regulation. Outputs 1 and 2 have active current share facilities for applications requiring parallel connection with other units. Unit inhibit, power fail signal and LED status indicators are provided as standard. An optional signals card gives DC OK signal, fan fail signal and a +5V 100mA auxiliary supply for external functions. Input connection is either by standard, quick connect IEC lead or, optionally, to a screw terminal block. Output connection up to 20A is by standard, quickmate, multi-pole plugs (available as an accessory.) Output 1 connection is via M4 mounting screws on angled busbars. The VWF350 complies with EN60950 being CE marked to the Low Voltage Directive and is safety approved to both UL1950 and CSA 22.2 No. 234. The unit is designed to meet current and pending International EMC Directive requirements.

NEW INTRODUCTIONS - The Kestrel family is being extended with a 48Vdc input version available December 1997. Similar power supplies can be specified to support both ac mains input or 48Vdc input, with a single footprint. Also available is a range of single output units (VWS400) in the same style, described in a separate data sheet. If you cannot see your exact requirement here, please give us a call.

Voltage Range 85 264Vac 120 350Vdc (48Vdc input version available Dec. 1997. Input range 40 75Vdc.) Frequency 47 63 Hz Supply Type Single phase TN-S systems (as defined in IEC364). Input Current 5.7A maximum at 90V input, 350W output 2.3A maximum at 198V input, 350W output Inrush Current 10A maximum, hot or cold start Power 460W maximum input power when delivering 350W output power Power Factor Greater than 0.95 at 350W output power, 100 to 240V input voltage. Typically 0.99. Efficiency Typically 80% at 350W output power, 230V input Harmonic distortion Complies with the requirements of EN61000-3-2.
OUTPUT SPECIFICATION
Voltage Nominal output voltages and adjustments are shown in tables 1-5. Adjustment is by means of a 20-turn potentiometer. Outputs are preset to within 6 1% of nominal. Current Recommended maximum continuous current ratings are shown in Tables 1-5. It may not be possible to draw full rated current from all outputs simultaneously due to total power rating of the unit. All maximum current ratings are applicable up to 50°C. From 50°C to 70°C derate by 2.5%/°C.
Line Regulation 0.2%VNOM maximum for an input variation over the operating range of the unit with all outputs proportionally loaded to provide 350W output power. Dynamic Regulation Outputs 1 and 2: 250mV maximum deviation, recovering to 1% of nominal within 1ms. Outputs 3 to 5: 5%VNOM maximum deviation, recovering to 1% of nominal within 1ms. Both of the above apply when the load varies 50% to 100% or 100% to 50% of IMAX. Temperature Coefficient
Surge Current Up to 24A is available from output 2. This is fully supported by a surge power capability of up to 500W total output power. The peak current on output 2 is limited to 26.4A 6 2.4A, reducing after about 3s to reach 14.4A 6 1.8A within 8s. The limit then resets to 26.4A 6 2.4A within 1s of removal of the overload. See output current limit under "Protection." The average current over a 1 minute period must not exceed 12A. Power 350W continuous up to 50°C. From 50°C to 70°C derate by 2.5%/°C. Surge Power Up to 500W surge power is available from the power supply. Typically, the surge power is available for 15 seconds in any 1 minute period. Load Regulation 1%VNOM maximum for an output current variation of 0 to 100% IMAX with all other outputs loaded to 20% IMAX. The output voltage of any output is independent of the load current on any other output.
Typically 6 0.02%/°C on all outputs for the temperatures within the operating range. Ripple and Noise 1% or 50mV pk-pk (whichever is greater) over 500kHz bandwidth, 1% or 100mV (50mV on output 1) whichever is greater over a 30MHz bandwidth. Measurements are differential with all outputs proportionally loaded to provide 350W output power.
TURN ON AND TURN OFF CHARACTERISTICS
Start-up Time All outputs are above DC OK threshold within 0.5s of application of input power at 240V, 1.5s at 100V Start-up Characteristics The voltage rise on all outputs is monotonic with no overshoot. Hold Up >20ms at 350W output power at any input voltage within the specified range. This is sufficient energy storage to ride through a missing mains cycle.
