450 WATT MEDICAL POWER SUPPLIES
DESCRIPTION
The TM450 series comprising single and multiple
output models for 450-480 watts of continuous
output power is specially designed for medical
applications. They operate at 90 to 264VAC input
voltage without the need of a selector strap. 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.

47 to 63Hz
Input current：
7.1A（ rms） for 115VAC
3.5A（ rms） for 230VAC
E a r t h l e a k a g e c u r r e n t： _{1 0 0 µ A m a x . @ 11 5 VA C , 6 0 H z}
165µA max. @ 230VAC, 50Hz
OUTPUT SPECIFICATIONS
Output voltage/current： See rating chart
Total output power：
See rating chart
Ripple and Noise：
2% peak to peak maximum
Overvoltage protection： Provided on output #1 only; set
at 115 – 140% of its nominal
output voltage
Overcurrent protection： All outputs protected to short
circuit conditions
Temperature coefficient： All outputs ±0.04%/ºC maximum
Transient response：
Maximum excursion of 4% or
better on all models, recovering
to 1% of final value within 500µs
after a 25% step load change
PFD signal：
Remote inhibit：
TTL logic high for normal
Operation and TTL logic low
upon loss of input power. This
signal appears at least 1ms prior
to master output dropping
5% below its nominal value.
This signal also provides a
minimum delay of 100ms
after master output is within
regulation.
Requires an external TTL high
level signal to inhibit outputs for
standard models.
