GE Optima CT Voltage Stabilizer Application Case | CT670 / CT680 / CT620 Power Protection Cases
What capacity voltage stabilizer does a GE Optima CT need? This is a real application case of Winzele providing voltage stabilization solutions for three GE Optima CT models — CT670, CT680 and CT620. The CT670 and CT680 were configured with 150kVA stabilizers (SBW-150KVA) and the CT620 with a 120kVA stabilizer (SBW-120KVA); this stabilizer series has been running stably at GE CT scanning sites for many years.
The GE Optima CT670, CT680 and CT620 are all high-end precision medical imaging equipment, and different models and different sites have different power supply requirements. Winzele stabilizer capacity must be matched to the equipment model, rated voltage, load characteristics and on-site power supply conditions — the same model cannot simply copy the same configuration at a different site. The Winzele Voltage Stabilizer is installed between the low-voltage power supply system and the GE Optima CT scanner, providing stable voltage to the CT main unit power circuit.

Why CT Systems Need a Voltage Stabilizer
CT equipment sites may be affected by grid voltage fluctuation, long-distance line voltage drop, load changes within the medical facility and regional grid condition differences. These factors can cause voltage instability in the equipment power supply circuit.
All three GE Optima CT sites in this case are new CT scanner installations in existing hospitals. Some of the medical facilities’ original power distribution systems did not dedicate a separate transformer to the equipment area; combined with line distances and shared power circuits, there is a risk of voltage fluctuation. Therefore, when installing in a new area, the equipment input requirements, on-site distribution circuits and grid conditions must be verified.
A CT scanner voltage stabilizer (CT scanner voltage stabilizer) sits in the equipment power supply chain, regulating the input voltage to provide stable supply voltage to the connected CT system and reduce the impact of voltage fluctuation on CT operation. The typical stabilization range covers input voltage of 380V±20%, with output stabilized at 380V or 400V±1%; remote monitoring functions can be added per site requirements.

Voltage Stabilizer Capacity Selection Reference
Based on Winzele’s long-term project experience in medical imaging equipment stabilization and multiple GE CT series application cases, stabilizer capacity matching requires comprehensive verification of the following information:
| Check Item | Description |
|---|---|
| Equipment model | E.g. GE Optima CT670 / GE LightSpeed and other models |
| Rated voltage | Varies greatly by region worldwide; commonly 400V / 415V / 440V / 480V |
| Frequency | 50/60Hz |
| Site voltage condition | Winzele stabilizers cover common 380V±20% voltage fluctuation; final values subject to on-site measurement |
| Load characteristics | Depends on the CT model/specification and original manufacturer requirements |
Voltage stabilizer selection for medical imaging equipment requires comprehensive consideration of the equipment rated capacity, input voltage range, load characteristics and on-site power supply conditions. For detailed application notes, see Medical Equipment Voltage Stabilizer Solutions.
Global Voltage Adaptation
Rated voltage, frequency and voltage fluctuation ranges differ by country and region, so the same GE Optima CT series requires separate electrical parameter matching at each site. China projects commonly use three-phase 380V, 50Hz; overseas projects must verify the local voltage (e.g. 400V, 415V, 440V, 480V) and frequency (50/60Hz) against the equipment version and cannot directly reuse existing China project parameters.
Frequently Asked Questions
Q: What capacity voltage stabilizer does a GE Optima CT need?
A: It depends on the equipment model, load characteristics and on-site power supply conditions. In this case, the CT670 and CT680 were configured with 150kVA and the CT620 with 120kVA (all actual project configurations), which does not represent a universal capacity for all GE CT equipment; other models or sites need independent evaluation.
Q: How do I choose a voltage stabilizer for an overseas GE CT project?
A: Re-verify against the equipment version and the local power supply system: rated voltage (e.g. 400V, 415V, 440V, 480V), frequency (50/60Hz) and the on-site voltage fluctuation range, then determine the stabilizer input, output and regulation scheme. China project parameters cannot be copied directly.
Q: Does legacy hospital CT equipment replacement need a voltage stabilizer?
A: The original power distribution system in a legacy hospital may not have a dedicated transformer for the equipment area; combined with line distances and shared power circuits, there is a risk of voltage fluctuation. It is recommended to first verify the on-site voltage conditions, then evaluate the stabilization solution.

Project Experience
The above cases of three GE Optima CT models demonstrate the real application of the Winzele Voltage Stabilizer at different medical imaging equipment sites. This stabilizer series has a long record of stable operation at GE CT scanning sites and is also widely applied at GE CT scanner sites in other hospital imaging departments. Equipment versions and distribution conditions vary by site, so configurations still need to be verified separately.

CT Voltage Stabilizer Application Guidance
Overseas CT projects may have different voltage levels, frequency standards, and site power conditions compared with previous installations. The voltage stabilizer configuration should always be verified according to the actual CT model, equipment requirements, and local power system conditions.
To evaluate a suitable voltage stabilization solution for GE CT or other medical imaging equipment, please provide:
- CT equipment model
- Equipment nameplate information
- Rated voltage and frequency
- Site voltage fluctuation range
- Installation conditions
- Load characteristics
Winzele engineering team will evaluate the power conditions and recommend a suitable voltage stabilization solution based on the actual project requirements.
