DE SC RIP TIO N
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.

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.
