Product Overview
The air compressor control transformer is an essential electrical spare part for screw air compressor control cabinets. It supplies stable low-voltage power for control circuits, solenoid valves, relays and indicator lights. It serves as a direct replacement for Atlas Copco, Sullair, CompAir, Ingersoll Rand and other mainstream screw air compressor brands. Built to withstand harsh industrial conditions including oil mist, dust and frequent start-stop surges, it stabilizes voltage and prevents unexpected shutdowns or control board burnout caused by grid fluctuation, cutting your downtime losses.
Key Features
✅ 100% Pure Copper Winding, Low Temperature Rise High-purity enameled copper wire winding delivers superior conductivity, less heat generation and low temperature rise under continuous load. It avoids burnout and enjoys much longer service life than aluminum-wound transformers.
✅ High Permeability Silicon Steel Core, Low Loss & Quiet Operation Premium laminated cold-rolled silicon steel sheets reduce no-load loss and electromagnetic noise. Stable output voltage with strong anti-interference performance, keeps control signals steady under unstable grid power.
✅ Flame-retardant Housing & Enhanced Insulation Safety Flame-retardant and high-temperature resistant casing with vacuum impregnation treatment, moisture-proof, dust-proof and shock-resistant. Reinforced insulation separates high and low voltage for safer operation in tough workshop environments.
✅ Wide Voltage Options & Direct OEM Replacement Multiple VA ratings & input/output voltage combinations (380V/220V, 380V/24V etc.), custom voltage available. Mounting dimensions match original parts for simple, fast installation.
✅ Heavy-duty Continuous Operation & Strong Overload Resistance Designed for continuous industrial duty cycle, capable of handling frequent start-up surges of air compressors. Ideal for 24/7 running compressed air stations.
