Default Ray Allen servo power

How much current does a Ray Allen servo draw under full load? I failed to find this info anywhere.

I remember it being an amp. Should be easy to verify with some searching.

The Ray Allen servos draw approximately 150 milliamps no load, this from their web site. Can't imagine it's a very high number fully loaded, I wouldn't think more than 300 milliamps.

Thanks Pat. I'm driving my trim servo with a TI SN754410 H-bridge and it gives 1A output so it will be sufficient.

Hans, these drivers will lose about 2 volts in drive voltage, causing the trim motors to slow down. This may not be an issue for you, but if it is, let me know.

Default 800 milliamps

I was sure it was 800 milliamps but it took me a while to find the source. It's in the FAQs section on the Ray Allen website:

"What kind of circuit breaker and wire should I use?
The full stall current of the T2 and T3 servo is only 800 milliamps. "
