Frequently Asked Questions

ROCOIL TCA-5

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.

No, clipping the output signal does not harm the TCA-5.

Why does the TCA-5 run so hot?

Each channel dissipates approximately 5 watts of heat at full power.

The TCA-5 has a peak internal current of 19 amps.

Is there a 24 volt version?

Not at this time.

The TCA-5 can be used on single-phase circuits, however there is currently no “1 channel model.”

The TCA-5 includes a 90 degree phase shifter. It can only be used with 333mV sensors to report current, NOT POWER.

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.
