Description
The Brahma NDE11 37510002 combustion manager is used to equip gas and liquid fuel burners with intermittent operation, without a fan. The microprocessor provides high control accuracy. The compact design includes an ignition transformer and a filter to minimize electromagnetic interference.
More about Brahma NDE11
The Brahma NDE burner control unit, together with connected devices, ensures safe ignition of the fuel mixture and control of flame combustion. Depending on the type of burner, the flame detector is either an ionization electrode or an FD photodetector. If ignition does not occur within the allocated time or if the flame is lost during burner operation, the combustion manager immediately initiates a protective shutdown. Electrical reset is provided to exit the lock-out state.
The controller and working components are protected by a compact housing made of impact-resistant, heat-resistant plastic. The necessary level of dust and moisture protection is achieved upon installation at the place of operation.
Main parameters and features
- operation from a stationary 220-240 V, 50/60 Hz network;
- intermittent cycle, controlled restart after 24 hours of operation;
- self-checking function of components to increase safety;
- high-efficiency ignition transformer;
- EMC filter to reduce electromagnetic interference;
- instant response when flame is not detected, response time < 1 sec.;
- small PCB size to reduce device dimensions;
- ionization electrode or FD photodetector for flame control;
- indication of operating status and faults;
- varistor for protection against peak voltages in the power supply network;
- electrical lock-out reset;
- admissible ambient air temperature range: -20...+70 °C;
- dust/moisture protection class IP 00 (implemented during installation);
- compact design, simple installation and connection;
- fixation in any position.
Protection against low voltage in the power supply network is provided. The automation switches off when the voltage drops below 175V. Switching on occurs automatically after the network parameters are restored.
Application
Brahma NDE burner control units are used in atmospheric burners that burn gas or liquid fuel. They are used to control the operation of heating boilers, combined and steam boilers, hot air generators, water heaters, convector heaters, washing machines, furnaces, IR heaters and other industrial equipment.
