RoCoil TCA-5 FAQs
-
Can the TCA-5 be used with 333mV current sensors?
The TCA-5 includes a 90 degree phase shifter. It can only be used with 333mV sensors to report current, NOT POWER.
-
Does output clipping damage the unit?
No, clipping the output signal does not harm the TCA-5.
-
How can I tell if the amplifier is clipping?
The voltage across the output terminals is above 250mV RMS. Correct this by using a larger wire gauge or moving the TCA-5 closer to the meter.
-
I had the 50Hz selector on by mistake. Is my collected data any good?
Yes, the phase angle will be reported 0.6 degrees higher than actual, which is also about 0.6% low for a PF of 0.866.
-
Is there a 24 volt version?
Not at this time.
-
Is there a single phase version?
The TCA-5 can be used on single-phase circuits, however there is currently no “1 channel model.”
-
Is there any configuration that can cause the TCA-5 to fail?
Yes. For example, over-ranging the TCA-5 on any single channel can burn it out. Ensure that the TCA-5 is not delivering more than 5 Amps RMS.
-
Why does the TCA-5 run so hot?
Each channel dissipates approximately 5 watts of heat at full power.
-
Why is the TCA-5 limited to 4.5 Amps RMS on 3 single-phase loads?
The TCA-5 has a peak internal current of 19 amps.
