COOLING
Integral fans provide forced-air cooling to ensure safe operation under all environmental
conditions. Care must be taken not to obstruct intake and exhaust ports.
SHOCK & VIBRATION
The UltraFlex power supply meets the performance requirements of IEC68-2-27; 15g, 11ms
half-sine pulses.
The UltraFlex power supply meets the performance requirements of IEC68-2-64 with a
frequency range of 20 - 2000Hz and acceleration of 6 Grms for a minimum of 30 minutes.
PACKAGE DROP
The UltraFlex packaging has been tested per National Safe Transit Association Project 1A.
RELIABILITY PREDICTION
Reliability prediction MTBF by stress method per Bellcore TR-NWT-000332 Issue 4 (reliability
prediction procedure for electronic equipment).

GLOBAL SIGNALS
The following signals are provided as a standard feature on the UF1500 via J3. Logic level
signal outputs are via open drain Mosfets (60VDC/100mA max ratings). Pull up resistors are
required. Signals are referenced to the Signal Common terminal (J3 Pin 3) on the interface
connector.
5V DC Standby Output (J3 pin 1):
Isolated 5VDC/0.3A output available whenever the input power is applied. This output is not
affected by inhibit signals. Load regulation less than or equal to 5%.
Global Output Good LED Drive (J3 pin 2):
An open drain output to light an external LED indicator. If any output equipped with a DC
output good option fails, this signal goes low. An internal 390 ohm series resistor limits the
current through the LED.
Global Output Good (J3 pin 4):
When all output modules which have Output Good signals are within specification, this signal
is high. If any output fails, this signal goes low.
