Brahma MF2 18015002 burner control unit is designed for full control of the combustion process of fuel. Technical specifications Supply voltage: 220V (-15%+10%) 50 Hz (±5%) Consumption - maximum 30 kg /hour. Operating temperature range: -10°C +60°C Degree of protection: IP40 Power consumption at startup: 9 VA Power consumption during operation: 3.5 VA Rated contact current: - Burner motor: 4 A - valves (EV1, EV2): 2 A - Ignition transformer: 2 A - Alarm: 1 A - regulators (T, PA, PG): 6 A Time: - pre-preparation time (TV): 30 s - response time (TS): 3 s - shutdown time when the working flame is turned off: <1 s - delay between EV1 - EV2: 30 s - time after purging: 5 s Flame control: - minimum ionization current: 0.5 µA - recommended ionization current: 7 µA - minimum insulation resistance of the cable and the flame detection device relative to the ground: > 50 mOhm - voltage on the detection sensor: 350 V - recommended operating voltage with phototube: >15 µA Weight with socket: 600 g Power consumption: 9 VA. Application    - Suitable for gas and fuel oil traction burners designed for both civil and industrial use.    - Works with burners having two flame levels. Construction The components of the Brahma MF2 18015002 relay are securely mounted on a frame made of pressed heat-curing material with high dielectric resistance. For additional protection of the control panel from mechanical damage, as well as from dust and dirt penetrating inside during installation, a durable housing is provided. Flexible unipolar conductors of various sizes connect all components of the control system, excluding only the flame detection and pre-purge circuit, which are effectively integrated on the printed circuit board. This constructive approach ensures reliable communication between the elements of the system, preventing possible malfunctions and ensuring a long service life of the equipment. Flame detection sensor - Can alternatively be used as a probe using the flame rectification property (ionization).    - Can also work with UV phototube. Certification and compliance with standards    - According to TÜV Bayern, Monaco, the control system complies with the German regulations DIN 4788, Part 3, for power up to 350 kW.    - Received the approval of DIN-DVGW 89.09fBN, although its validity has expired and is not subject to renewal. Testing and certification    - "Macintosh and Thermal Engineering Laboratory at the Studi ed Esperienze Center" in Rome - Capannelle tested the MF2 control system with a power of up to 2332 kW.    - The system has received certificate No. 3704/187/77/21.    - The approval of the Ministry of Internal Affairs on Fire Safety (Circulars No. 68 and No. 42) emphasizes the safety and compliance with the standards of this control unit.
