Medical Grade Isolation Power Transformers (VPM Series)
Triad Magnetics’ VPM Series medical-grade isolation transformers are designed for critical applications where patient safety, low leakage, and EMI performance are essential. These toroidal power transformers incorporate electrostatic shielding and a magnetic flux band to minimize common-mode noise and stray magnetic fields in sensitive medical and industrial environments.
The VPM Series offers a wide range of standard configurations, enabling design engineers to quickly identify a suitable solution without requiring custom magnetics.
Key Features & Selection Range:
- Power Range: 25 VA to 10 kVA
- Universal Input: Dual primary windings (100 / 120 / 220 / 240 VAC) for global applications
- Flexible Outputs: Series and parallel secondary configurations for step-up, step-down, and isolation
- Low Voltage: 6 V to 50 V
- Isolation: 120 V / 240 V
- High Isolation: 4,000 Vrms primary-to-secondary isolation
- Shielding: Electrostatic shield and flux band for reduced leakage current and EMI
- Low Stray Field: Toroidal construction minimizes magnetic radiation for sensitive equipment
- Mounting: Chassis mount with wire leads for robust installation
- Safety Approvals: UL Recognized component, certified to IEC / UL / CSA 60601-1 medical standards, including 2 MOPP (Means of Patient Protection) isolation
Typical Applications:
- Medical equipment and patient-connected devices
- Diagnostic and imaging systems
- Laboratory instrumentation
- Isolation for critical power systems
- Industrial equipment requiring low noise and high isolation
Triad’s toroidal construction enables compact size, high efficiency, and low audible noise compared to traditional EI transformers, making the VPM Series ideal for space-constrained and noise-sensitive designs.
