Unidad de control de combustión Brahma NDE31, C00100433

Brahma NDE31 burner control unit (art. C00100433) is a microprocessor-based burner manager designed for automation of ignition, control and safe operation of forced draught (fan-assisted) gas and liquid fuel burners. The device operates in intermittent mode and provides a full cycle: pre-purge, ignition, continuous flame monitoring and safety lockout. The NDE31 model features a full pre-purge, making it an optimal choice for burners with forced air supply. Main technical specifications: Parameter Value; Supply voltage 220–240 V, 50/60 Hz; Flame control Ionization or photodiode FD; Burner type Forced draught, two-stage, progressive; Fuel type Gas, liquid fuel; Operating mode Intermittent; Pre-purge time 15 seconds (fixed); Safety time (Ts) 5 seconds; Operating temperature from -20°C to +70°C; Protection class IP40; Dimensions (H×W×D) 10.7 × 8.1 × 3.6 cm. Key features: Built-in high-voltage ignition transformer — no external unit required. Microprocessor control with self-diagnostics and LED indication of modes/faults. Full pre-purge (15 seconds) — cleans the combustion chamber of residual fuel before ignition. Universal flame control — ionization electrode for gas or photodiode FD for liquid fuel. Multiple ignition attempts — increases start-up reliability. Flame loss protection — lockout if flame disappears within Ts. Electrical lockout reset — simply disconnect power briefly. Compact housing — convenient for mounting in a control cabinet. Applications: Forced draught gas and diesel burners (including two-stage and progressive); Industrial and domestic heating boilers.
