Operating Environment:
The Input Voltage Selector Switch is a 3-position slide switch located
behind the supply’s main capacitor. It is used to select one of three
tap points on the main transformer, providing a convenient way to
adjust for low, medium, or high local line voltage.
The E3PS12-75 is warranted to be free from defects in workmanship
and materials for a period of 36 months from date of purchase.
Three Year Warranty
Procedure: Setting The Input Voltage Selector Switch
Note:
Remove AC power and discharge supply before adjusting.
1. Initially set switch to
High
voltage setting as shown above.
2. Turn on AC line power to supply.
3. Status LED should blink rapidly (16 Hz).
4. Move switch to progressively lower settings until
Status LED turns on solid.
5. Back up one position until Status LED blinks rapidly.
(Most applications use the center (Med) position.)

When an axis decelerates rapidly the motor behaves like a generator,
sending energy from the motor phases back into the power supply.
This becomes a problem when this regenerated energy exceeds the
supply’s ability to absorb it, and can cause the DC output to spike.
The E3PS12-75 automatically channels the right amount of regener-
ated energy back into the supply, while safely dissipating the rest
across a bank of dump resistors. This has the dual benefit of captur-
ing and using “free” energy while protecting the power supply from
potentially damaging voltage levels.

Note: Teknic does not supply or sell a 230VAC input cable for this product. A wiring
table for 230VAC cable is available on page 1 of this document.
Regen Note:
The first few times the supply dissipates energy
across the dump resistors a small amount of smoke may be seen.
This is normal and will stop after the initial burn off occurs.
