Cofi TRS820PISO ignition transformer

Ignition transformer COFI TRS820PISO (part number 309.820.089) — isolated Italian transformer 115V with single output 8 kV. COFI TRS820PISO is a specialized high-voltage ignition transformer with isolated pole (PISO) from Italian manufacturer COFI. The model is designed for reliable ignition in gas and liquid fuel burners of small and medium power, especially on diesel and fuel oil. Thanks to the isolation of the high-voltage pole and improved characteristics, it provides a stable and powerful spark in various operating conditions. Main technical specifications: Power supply: 115 V, 50/60 Hz, 2 A Output voltage: 1 × 8 kV (peak up to 11 kV) Ignition current: 20 mA Duty cycle: 33% ED (within 3 minutes) — improved cycle compared to standard models Type: Traditional electromagnetic, isolated pole (Insulated) Dimensions (net): 140 × 86 × 66 mm Weight: 1.827 kg (net) / 1.902 kg (gross) Connectors: standard Ø 4 mm for high-voltage cable Compact housing with durable epoxy filling reliably protects windings from overheating, vibration and humidity. The isolated design increases safety and expands application possibilities. Advantages of COFI TRS820PISO: Isolated high-voltage pole — increased safety and installation flexibility. Improved duty cycle (33% ED) — suitable for more intensive use. Excellent ignition on diesel, fuel oil and waste oil. Italian COFI quality according to CEI EN 61558-2-3. Wide compatibility with burners Riello, Ecoflam, FBR, Baltur, Lamborghini, Bentone, Giersch and other brands. The transformer is ideal for service centers, heating equipment manufacturers and boiler houses using 115 V equipment. It ensures reliable ignition, reduces the number of
