CT MACHINE ELECTRICAL PANEL
RuncoN CT Machine Electrical Panel is the main electrical control and distribution unit for a Computed Tomography (CT) scanner system. It manages and protects the electrical power supply to all parts of the CT system — including the gantry, X-ray tube, generator, table, console, and cooling system.
Main Functions
- Power Distribution: Receives power from the hospital's main supply or UPS (usually 400/230 V AC, 3-phase) and distributes it to subsystems including gantry, table, and computer systems.
- Power Conditioning: Ensures clean and stable power using transformers, filters, and voltage regulators.
- Protection: Includes circuit breakers, fuses, surge protectors, and emergency shutoff switches to protect both equipment and operators.
- Control and Monitoring: Includes status indicators, alarms, and interlocks for safety and maintenance. Often integrates with the Building Management System (BMS).
Typical Components
| Component | Function |
|---|
| Main Circuit Breaker | Disconnects the entire system from power. |
| Isolation Transformer | Provides galvanic isolation and voltage matching. |
| Power Contactors & Relays | Control power flow to subsystems. |
| Surge Protection Device (SPD) | Protects against lightning or transient overvoltage. |
| Emergency Stop Button | Immediately cuts power to the CT scanner in an emergency. |
| Cooling Fan / AC | Keeps panel temperature stable. |
| Grounding and Bonding | Ensures electrical safety and noise reduction. |
| Control Switches & Indicators | For manual control and system status display. |
Power Requirements
| Parameter | Value |
|---|
| Input Supply | 400 V ±10%, 3-phase, 50/60 Hz |
| Power Rating | 60–100 kVA (depending on CT model) |
| Dedicated Line | Requires a dedicated power line and isolated ground |
| UPS / Backup | Computer systems connected to UPS for uninterrupted operation |
Installation and Safety
- Must comply with IEC 60601, NFPA 99, and local electrical codes.
- Located in a technical room adjacent to the CT scanner room.
- Requires proper grounding, shielded cables, and environmental control (temperature and humidity).
