Power transformer R-20VA 110V/110V-40V/24V

instrumentmeasurementR-core

20VA R-core Precision Transformer for Testing Applications (VPI-Processed) Designed for critical testing and measurement systems, the 20VAR transformer leverages Vacuum Pressure Impregnation (VPI) technology to deliver unmatched accuracy, efficiency, and quiet operation. Ideal for labs, calibration setups, and sensitive electronics, it ensures reliable performance in environments demanding ultra-low noise and stability. Key Features: 1.VPI-Enhanced Insulation System a. Vacuum Pressure Impregnation ensures complete resin penetration, eliminating air voids for superior dielectric strength (≥50kV) and moisture resistance. b. Extended thermal lifespan (H-class, 180°C) with reduced partial discharge (98% efficiency, minimizing energy loss in continuous duty. b. Noise levels <40dB via vibration-dampened laminations and epoxy-encapsulated windings, critical for EMI-sensitive environments. 3.Sub-1% Precision Stability a. Tight voltage regulation (±0.5%) and near-zero temperature drift (±0.02%/°C) ensure repeatable results in precision instruments. b. Shielding layers and twisted-pair leads suppress electromagnetic interference (EMI/RFI) to µV-level signals.
