300 WATT MEDICAL POWER SUPPLIES
DESCRIPTION
The TM300 series comprising single and multiple
output models for 200 to 300 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. All
auxiliary outputs are with magnetic amplifier to
keep regulation. 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.

at 115–140% of its nominal
output voltage

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.
