300 WATT MEDICAL POWER SUPPLIES

DES C RI P T I O N

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.

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：

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.

Remote inhibit：

Requires an external TTL

high level signal to inhibit

outputs for standard models.
