Canon DR Voltage Stabilizer Solution | 100kVA Voltage Stabilizer Application Case
What capacity voltage stabilizer does a Canon DR (digital radiography) system need? This case provides a verified answer: a Canon DR system at a medical imaging facility in China was configured with a 100kVA Winzele voltage stabilizer, which was the actual capacity for this project.
DR has different load characteristics from CT and MRI: the X-ray generator produces a high power peak at the moment of exposure, but each single exposure is short and the equipment operates intermittently — a DR voltage stabilization solution is matched to exposure peak demand + intermittent load characteristics, rather than the continuous scanning impact of CT or the sustained running load of MRI.
Fig. 1 shows the on-site installation of the Canon DR digital radiography equipment with the 100kVA Winzele voltage stabilizer.
Why the Canon DR System Needs a Voltage Stabilizer?
The Canon DR is a digital radiography imaging system. During exposure, the X-ray generator momentarily draws high power, placing demands on the voltage stability of the power supply circuit. Common power supply issues in real medical imaging scenarios include:
- Grid voltage fluctuation
- Load changes in the hospital power distribution system
- Voltage dip at the instant of X-ray exposure
- Regional grid condition differences
When these factors exceed the equipment’s allowable range, they can affect DR imaging stability and image quality. The role of a voltage stabilizer is to regulate the fluctuating input voltage to within the equipment’s allowable range, providing a stable power environment for the DR system. For a full introduction to DR voltage stabilization solutions, see DR Digital Radiography Voltage Stabilizer Solutions.
What Determines the Voltage Stabilizer Capacity?
The power supply configuration of a DR system must be matched to the equipment model, load characteristics and on-site electrical conditions. For a specific project, the X-ray generator parameters and the equipment’s allowable voltage range should also be verified to determine the engineering configuration of the stabilizer and the power supply circuit.

Capacity Basis
The 100kVA capacity used in this project comes from the confirmed on-site actual configuration. The voltage stabilizer capacity should be consistent with the equipment nameplate and measured on-site parameters, rather than inferred from the equipment brand or equipment type. Other DR projects still need to independently evaluate capacity based on the equipment model, X-ray generator parameters, load characteristics and on-site electrical conditions.
How DR Stabilizers Differ from CT and MRI Stabilizers
| Equipment Type | Load Characteristics | Stabilization Focus | Reference Case |
|---|---|---|---|
| CT | Peak current impact during scanning, continuous scanning | Peak current, multi-slice continuous scanning | Siemens CT · GE CT · Philips CT |
| MRI | Superconducting magnet continuously powered, cryogenic cooling system running 24h, strong magnetic field environment | Power supply continuity, magnet and cooling loads | Siemens MRI |
| DR | High power peak at the exposure instant, short single exposure, intermittent operation | Exposure peak demand, intermittent load | this page |
The three equipment types have different power consumption characteristics. Voltage stabilizer capacity and circuit configuration cannot be reused across types and must be evaluated separately by equipment category.
Overseas Projects: Are a Voltage Stabilizer and a Transformer the Same Thing?
DR projects in China commonly use three-phase 380V, 50Hz power supply, but the equipment version and actual project parameters must be verified individually. Overseas 400V, 415V, 440V, 480V and 60Hz systems should have their stabilization, transformation and circuit configurations determined according to the specific Canon model.
Stabilization ≠ transformation: transformation addresses voltage level differences (e.g. conversion between 380V and 480V), while stabilization addresses voltage fluctuation (e.g. stable output under ±15% fluctuation). If the equipment and site voltages differ, the functional boundary between the two should be clarified at the solution stage and checked separately, to avoid treating the two functions as the same parameter.
Frequently Asked Questions (FAQ)
Q: What capacity voltage stabilizer does a Canon DR need?
A: It depends on the equipment model, X-ray generator parameters, load characteristics and on-site electrical conditions. DR systems usually have different peak power requirements during X-ray exposure, so capacity selection should not be based only on average power consumption.This case used 100kVA (actual project configuration), which does not represent a universal capacity for all Canon DR or DR equipment; other projects need independent evaluation.
Q: Is the voltage stabilizer for DR equipment the same as for CT equipment?
A: No. CT involves peak impact during scanning and continuous scanning; DR involves a high power peak at the instant of exposure, short single exposures and intermittent operation. The two have different load characteristics, so capacity and circuit configurations cannot be reused interchangeably.
Q: Are a voltage stabilizer and a transformer the same thing?
A: No. A transformer addresses voltage level differences (voltage conversion), while a voltage stabilizer addresses voltage fluctuation (stable output). When equipment and site voltages differ, both need to be configured separately with clear functional boundaries.
Q: How do I choose a voltage stabilizer for an overseas project?
A: Verify the local voltage (e.g. 400V, 415V, 440V, 480V) and frequency (50/60Hz) against the equipment model, then determine the stabilization, transformation and circuit configuration. Parameters from a China project cannot be copied directly.
