Teknic E3PS12-75 Quick Reference

Teknic E3PS12-75 Power Supply Quick Reference
Introduction
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
● Automatic DC bus dump on power down.
● Easy adjustment for high, medium or low AC line voltage.
● Intelligent regenerative energy management.
● Embedded microcontroller.
* Note: Teknic does not supply or sell 230VAC power cables for this
product. Users operating at 230VAC must build or otherwise source
this cable. Cable pinout can be found under "Mating Connectors" at right.
General Safety
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.
Mounting 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.
