GE Logiq 3 Low Voltage Power Supply (LVPS) PN 2319545-2 Review

When a GE Logiq 3 ultrasound system loses power or fails to boot, the low voltage power supply is one of the first components to suspect. Downtime in a clinical or imaging setting is costly — and tracking down a reliable LVPS replacement quickly matters. This review covers everything you need to know about the GE Logiq 3 LVPS (Part Number 2319545-2), including what it does, where to source it, and how to evaluate condition before you buy.

Product Overview

The GE Logiq 3 Low Voltage Power Supply (LVPS), part number 2319545-2, is an internal power conversion module used in the GE Logiq 3 cart-based ultrasound system. It converts AC mains input to the regulated low-voltage DC rails that power the system's imaging boards, monitors, and peripheral components.

Who needs this part?

• Biomedical engineers responsible for maintaining diagnostic imaging equipment
• Independent ultrasound repair technicians
• Hospitals and imaging clinics managing legacy GE Logiq 3 systems in-house
• Equipment refurbishers and resellers

The GE Logiq 3 is a mid-range general imaging system that saw wide deployment in the early-to-mid 2000s. Many units remain in service globally — in developing markets, veterinary clinics, and smaller outpatient facilities — making reliable access to replacement parts like this LVPS an ongoing need.

What the LVPS Does

The low voltage power supply is a critical system component. In the Logiq 3, it supplies regulated DC voltages (typically +5V, ±12V, +24V, and others depending on board configuration) to:

• The main imaging processing boards
• The monitor and display system
• The front panel controls
• Probe interface electronics

When the LVPS begins to fail, common symptoms include:

• System fails to power on or powers off unexpectedly
• Intermittent shutdowns during scanning
• Display flickering or blanking
• Error codes or POST failures on startup
• Audible clicking or coil whine from the power section

If your Logiq 3 is exhibiting any of these symptoms, the LVPS should be among the first components bench-tested before replacing more expensive boards.

Hands-On Assessment: What to Evaluate When Buying Used

Because PN 2319545-2 is a service replacement part rather than a consumer product, most available units on the secondary market are pulls from decommissioned systems or refurbished stock. We evaluated this part based on sourcing criteria that matter most to biomedical technicians.

Physical Condition

A used LVPS should show no signs of:

• Bulging or leaking capacitors (inspect closely near the filter cap bank)
• Burn marks or heat discoloration on the PCB
• Cracked solder joints on high-current connectors
• Corrosion on the output terminals or board traces
• Physical impact damage to the housing

Sellers listing "tested, working" units are preferable, but verify what "tested" means — ideally, it means the unit was powered on under load conditions and output voltages were measured, not just that the unit powered a system briefly.

Connector Integrity

Check that all output harness connectors are intact. The LVPS uses multi-pin Molex-style connectors that can develop micro-fractures at the crimp points. Damaged connectors can cause intermittent faults that are difficult to diagnose once the unit is reinstalled.

Revision and Compatibility

PN 2319545-2 is the revision 2 variant. Confirm compatibility with your specific Logiq 3 variant (standard vs. Expert configuration) before purchasing. GE released the Logiq 3 in multiple regional configurations; a biomed with access to the system's service manual can cross-reference acceptable part numbers.

Pros and Cons

Pros

• Widely available on the secondary market for the Logiq 3 install base
• Standardized part number makes sourcing straightforward
• Swapping the LVPS is a relatively accessible repair for trained biomed staff
• Replacing a failed LVPS is significantly more cost-effective than whole-system replacement
• Refurbished units from reputable sources often carry a limited warranty

Cons

• Most available units are used/pulled — new OEM stock is essentially unavailable
• Quality varies significantly by seller; "tested working" claims are inconsistently verified
• Capacitor degradation in units of this age is common and may not be immediately apparent
• No direct aftermarket/third-party equivalent is widely available, unlike some other GE components
• Requires biomedical training to safely install and commission

Performance Breakdown

Who Should Buy This

• Biomed departments maintaining Logiq 3 fleets: If you have multiple Logiq 3 units in service, keeping a tested spare LVPS on the shelf is prudent inventory management.
• Independent repair technicians: This is a high-demand service part; having reliable supply access matters.
• Imaging centers extending the life of paid-off equipment: A $300–600 LVPS replacement versus a $15,000+ system upgrade is an easy calculation in favor of repair when the rest of the system is functional.
• International buyers in markets where Logiq 3 systems remain primary imaging tools: Secondary market sourcing is often the only viable path for parts in these regions.

Who Should Skip This

• Facilities with a Logiq 3 system that has multiple failing boards: A functioning LVPS won't save a system with cascading hardware failures. Get a qualified biomed assessment before ordering parts.
• Non-technical buyers: This is a component-level repair part. Without the tools, training, and safety protocols to work inside energized medical imaging equipment, this purchase won't help you.
• Anyone hoping for OEM warranty coverage: This part, in the secondary market, will not carry GE OEM warranty. Ensure your procurement process accounts for this.

Alternatives Worth Considering

If the Logiq 3 LVPS replacement doesn't solve your system issues, or if you're evaluating whether repair is worth the investment, consider these paths:

1. Full System Refurbishment via Certified Service Partner

If the Logiq 3 has accumulated multiple component failures, a GE-certified service partner or independent refurbisher may offer a flat-rate depot refurbishment. This covers known wear items including the LVPS, main board capacitors, and other high-failure components. Check current availability for refurbished GE Logiq series systems on eBay.

2. Upgrade to a More Current Platform

For facilities where the Logiq 3 is approaching end-of-supportable-life, exploring portable ultrasound systems may offer better long-term value. Modern portables have significantly advanced and can handle many use cases formerly requiring a cart system.

3. Apogee Cynosure Ultrasound System

For certain specialty applications, the Apogee platform represents an alternative ecosystem with its own parts supply chain worth evaluating alongside aging GE Logiq equipment.
