Notes

1

Maximum figure, at full load.

2Measured from high line to low line.

3Measured as load changes from no load to 100% full load.

4

The PM671 is available with optional voltage balance pin, and is

designated by suffix letter ‘P’. For connection information, see case

drawing. In addition, both the PM671 and PM672 are available with

alternate pin-out (including balance pin) designated by suffix letter ‘R’. See

case drawing. If not required, the balance pin can be left floating.

5Measured with a 15µF tantalum capacitor across each output.

6

On dual output models the four common pins are internally connected.

The outputs can be returned through one pin while the others remain

floating.

7

Standard specifications are conservative and can be optimized for specific

applications. In particular, converter start-up at lower than specified

temperature, wider input voltage range and output voltage adjustment are

all relatively simple modifications to the standard product. Consult factory

for details.

8

Fixed frequency design provides for easier input filtering and better noise

performance.

9

Units are tested with resistive load only.

10 Output current derates to 0 at 110% nominal Vin.

11 NOTICE: Some models do not support all options. Please contact your

local Artesyn representative or use the on-line model number search tool
