HeNe Power Supply

5.1.1. Introduction

The HeNe power supply is a turn-key power supply for HeNe laser tubes that incorporates all of the appropriate
safety features required by US federal regulations. Note that the power supply that came with your HeNe
laser is specifically designed to be used with that model of HeNe lasers and is not compatible with other
HeNe laser models.
This unit is RoHS compliant.

5.1.2. Remote Interlock Operation

To use the remote interlock connector, the metal pin needs to be removed, the top of plug taken out and the
shorting conductor from the connector removed. The connector may then be wired into the user's interlock
system. Be sure to reinstall the plastic safety cover over the interlock before use. The interlock is at AC line
potential and proper care must be taken to use the correct wire gauges, insulation types, etc.
The voltage on this connector is the same as the AC line voltage of your pre-configured power supply. Only the
provided connector should be used as an interlock and never anything else. Please contact your local tech
support office for a replacement connector.
Use of controls, adjustments, or performance of procedures, other than those specified herein,
