General Information
Introduction
Thank you for purchasing the PACE SODRTEK
®
model ST 145 Analog Desoldering System. This
manual will provide you with the information necessary to properly set up, operate and maintain the
ST 145.
The ST 145 system is available in either 115 VAC or 230 VAC versions, which incorporates a highly
responsive SensaTemp (closed loop) control system providing up to 80 Watts of total power to a
single output channel. The 230 VAC version system bears the CE Conformity Marking, which
assures the user that it conforms to EMC 89/336/EEC.
The 115 VAC version systems conform to FCC Emission Control Standard, Title 47, Subpart B, Class
A. This standard is designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment.
