SSI Power Supply for Logic Boards in Thermo Finnigan LCQ Mass Spectrometers

SSI SQM205-14433-2-A Power Supply Module for Thermo Finnigan LCQ Systems

The SSI SQM205-14433-2-A (SSI Part #20-0048-008) is a specialized switching-mode power supply designed for the Thermo Finnigan LCQ series mass spectrometers. This robust electrical module provides reliable DC power distribution for the instrument's sensitive electronic components and logic circuitry. Engineered for continuous operation in demanding laboratory environments, the SQM205 series ensures consistent voltage delivery with minimal fluctuation, which is critical for maintaining the operational stability of the LCQ Duo and LCQ Advantage hardware platforms.

Technical Performance and Design

• High-Stability DC Distribution: Provides regulated power rails essential for the instrument's main control boards, preventing logic errors and ensuring synchronized hardware interaction.

• Switching-Mode Efficiency: Utilizes advanced switching technology to deliver high power density while minimizing heat generation within the spectrometer’s electronics bay.

• Input Versatility: Features universal or jumper-selectable AC input (120/240VAC, 50/60Hz), making it compatible with global laboratory power standards.

• Integrated Protection Circuitry: Includes built-in safeguards against over-voltage and over-current conditions, protecting the spectrometer’s sophisticated analytical subsystems from electrical surges.
