Hi Group
I intend to use this for two of my steppers. I already have one power
supply in place. The two motors are 5 amps each with voltage rating
of 3.1. Could someone help with the transformer wiring. I`m not
certain how to configure the wires.

From a ebay auction:
You are bidding on a new 600VA toroidal transformer. It is precisely
made for high-end power amp or equipment. It has very low power loss
and magnetic leak. Labeled input 115 / 230 VAC 50/60 Hz (single coil
with center tap) and outputs 35VAC x 2 (dual coils). Mounting
hardware is included. The test results are excellent.
Voltage Test Result:
TEST CONDITION: Apply variable voltage to primary coil (115V
terminals) from 100-180VAC. No load on secondary coils.
1. Primary V = 100VAC, Primary I = .03A
2. Primary V = 110VAC, Primary I = .03A
3. Primary V = 120VAC, Primary I = .04A
4. Primary V = 130VAC, Primary I = .05A
5. Primary V = 140VAC, Primary I = .11A
6. Primary V = 150VAC, Primary I = .15A
7. Primary V = 160VAC, Primary I = .63A
Load Test Result:
TEST CONDITION: Input 120VAC 60Hz to the primary coil; parallel 2
secondary coils, 10 ohm 250W resistors as dummy load and room
temperature at 25 degree C. Temperature rises 6 degree C after an
hour test at load #5.
1. Primary I = 0.03A, Secondary V = 40.5VAC at 0.0A
2. Primary I = 1.36A, Secondary V = 39.6VAC at 3.96A
3. Primary I = 2.66A, Secondary V = 38.6VAC at 7.72A
4. Primary I = 3.92A, Secondary V = 37.9VAC at 11.37A
5. Primary I = 5.10A, Secondary V = 37.1VAC at 14.85A
