Re: Mach2 power consumption #Mach2GTO

Steppers always require more power/amps than servos.

Amps times volts equals watts.

Watts of electricity consumed converts 1:1 to watts of heat generated.

A typical AC-DC power supply is about 80-95% efficient, depending on design. That means another 5-20% of power consumption and heat generation.

Make sure your observatory and/or imaging setup is configured to minimize any impact these various heat sources will have on your local seeing.

I'm wondering what other Mach2 users are experiencing with power usage with their mounts.  

Using a Powerwerx watt meter, I'm seeing about 1.05 amps at 13.8V while tracking, as much as 5.15 amps while slewing.  I'm powering with a Pyramid PS-15KX supply, and it gets hot.  (Still indoors due to lousy weather).

These motors are drawing a lot of juice!  Is that to be expected?
