DESCRIPTION

This series of AC -DC switching power supplies in a

package of 4 x 7 x 1.58 inches are capable of delivering

400 watts of continuous power at 7 C FM forced air cooling

or 300 watts at convection cooling. The units are

constructed on a printed circuit board with a U-bracket for

mechanical support and heat sinking. A cover and fan

assembly can be added during manufacturing for 400 watt

output without the change of any dimension. They are

designed for medical applications, but not for life-

supporting equipment. The units are certified also to

IEC /EN/UL 60950-1 and suitable for data networking,

computer and telecommunication applications.

NOTES

1. C hange suffix “B” for U-Bracket form to “C ” for enclosed form with cover and fan assembly, e.g. PM400-14C .

2. 300 W without moving air or 400 W with 7 C FM forced air provided by user for “B” version, 400 W for “C ” version with

cover and fan assembly

3. Ripple and noise is maximum peak to peak voltage value measured at output within 20 MHz bandwidth, at rated line

voltage and output load ranges, and with a 10 μF tantalum capacitor in parallel with a 0.1 μF ceramic capacitor across the

output.
