Teknic E3PS12-75 Power Supply Quick Reference
Teknic model E3PS12-75 is a 75 VDC intelligent power supply
designed to provide the same reliable power and performance as its
predecessor (3PS12-75) with several added capabilities:
●Drop-in compatibility with Teknic SSt-3PS12-75.
●115 VAC or 230 VAC*nominal input voltage.
●Automatic DC bus dump on power down.
●Easy adjustment for high, medium or low AC line voltage.
●Intelligent regenerative energy management.
●Embedded microcontroller.

The E3PS12-75 should be installed and operated as specified herein.
Failure to do so may impair or defeat any protections provided by the
equipment. Please read and follow all instructions before installing or
operating this device.
General Safety
The power supply should be mounted behind covers or machine skins
that can only be opened with a tool. The covers or machine skins
should be marked as having hazardous voltages within. Alternatively,
the supply can be mounted behind doors that have a safety interlock
that removes power to the supply when opened.
The power supply should not be mounted in an area where the
ambient temperature exceeds 40°C.

Important: Use only the fuse type listed above regardless of AC line
voltage used. Using the wrong fuse can damage the power supply,
create a fire hazard, cause nuisance circuit breaker trips, and void the
product warranty.

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.
