DESCRI PTI O N

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.

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.
