Appendix A: Specifications
722
Rated voltage and current
See the label or nameplate on your PX3TS
model
Rated frequency
50/60Hz +/- 5Hz
Load power factor
0.60 to 1.00 (leading or lagging)
Non-linear load
Rated current up to crest factor 3.5
Sense and transfer time
4-8 milliseconds

None -- inlets may be any phase relationship
Phase sync resolution
+/- 5 degrees
Redundancy
Two power supplies.
The PX3TS continues to function on one
power supply.
SCR derating
At maximum continuous load, SCR switches
are running at 30% of the full rated current
and are running 50 degrees cooler than rated
semiconductor junction temperature
SCR protection
MOV (Metal Oxide Varistor) voltage transient
protection
Internal fault monitoring
▪
Switch open or short fault
▪
MOV surge protector failure
▪
Internal DC 12V power supply failure
▪
Overcurrent protector blow or trip
detection
Short circuit detection
The short circuit threshold varies depending
on the rating:
▪
16A models, such as PX3TS-1876R: around
45A
▪
24A models, such as PX3TS-1464R: around
68A
▪
32A models, such as PX3TS-1469R: around
91A
For details on the threshold calculation, see
Short Circuit Detection (on page 120).
Operating temperature
50°F (10°C) to 122°F (50°C)
