Brahma NDM11PR (art. 37505004) is a microprocessor “burner management unit” designed for reliable and safe control of atmospheric progressive burners operating on gas or liquid fuel in an intermittent cycle. The model combines all key ignition control and flame monitoring functions in a compact housing. Main technical specifications Parameter Value Supply voltage 220–240 V, 50/60 Hz Flame control Ionisation electrode or photodiode FD Burner type Atmospheric, progressive Fuel type Gas, liquid fuel Operating mode Intermittent Pre‑purge time 30 seconds Response time on flame loss less than 1 second Operating temperature –20 °C to +70 °C Protection class IP00 Base included No Dimensions (H×W×D) 10.7 × 8.1 × 3.6 cm Key features Microprocessor control system with controlled restart for periodic self‑checking of components. Built‑in high‑voltage ignition transformer – no external unit required, simplifying installation. Integrated EMC filter protects the device against electromagnetic interference. Universal flame control: works with an ionisation electrode (for gas) or a photodiode FD (for liquid fuel). Safety: on flame loss, the automatic system instantly (<1 sec.) interrupts fuel supply and locks out the burner. Lockout reset is manual via a button on the housing. LED indication of current status and fault codes for quick diagnostics. Robust housing made of impact‑resistant, heat‑resistant plastic protects the electronic components. Applications The Brahma NDM11PR burner management unit is used to equip atmospheric progressive burners in: Domestic and industrial heating boilers (gas, oil) Water heaters and water heating installations Hot air guns and IR heaters Furnaces and fireplaces Order codes 37505004, 246.124.240
