Brahma NDM32 Control Box 240v (Powrmatic)
The microcontroller-based controllers of the new digital Microflat series are an evolution of the digital Microflat “N” series and they are specifically designed to control burners with gaseous fuel (with or without fan in the combustion circuit), liquid or solid in non-permanent operation applications.

  • The automatic controllers of this series are suitable for:
  • Combi, Heating, Steam boilers;
  • Hot air generators, Radiant tube heaters;
  • Fan-assisted convector heater, Water heater;
  • Power washer, Furnaces, Monoblock burners;
  • Premix, Biomass burners or decorative fireplaces.

The new digital microflat series keeps the main features and reliability of the previous microflat and digital microflat series, and in addition it’s got accessories related to the control of wireless device, brushless motors, gas pressure and air flow rate and options related to the driving of auxiliary motors, direct current valves, modulating valves among which the new Brahma valve type VCMxx (with or without pressure control). Besides, this series can be employed also in appliances with liquid (oil) or solid fuel (biomass). The flexibility of the microcontrollerbase technology creates different possibilities related to the installation times and to the operation modes.

The systems of this series are suitable to be used in burners of gas in accordance with EN746-2, EN676, EN525, EN1020 and EN1319 standards, of oil in accordance with part 2 of DIN4794 standard (December 1980 edition related to the hot air generators, only in version TW=20s and TS=5s) or of biomass in accordance with EN303-5.

  • Features
  • EC- type certification (CE PIN 0476CQ0671) in accordance with Gas Appliances Directive 2009/142/EC (until 20 April 2018) and with Gas Appliances Regulation (EU) 2016/426 (from 21 April 2018)
  • conformity to EC directives, Electromagnetic compatibility* EMC (immunity) 2014/30/EU and Low-voltage directive 2014/35/EU
  • In accordance with EN298:2012 (European Standard for automatic gas and oil burner control systems and flame detection) and with EN60730-2-5 (European Standard for automatic controls with C class software)
  • A microcontroller based technology for precise and repeatable installation times, two independent safety contacts for driving the valve
  • Possibility to drive the Brahma modulating valve Type VCMxx and VCMxx *S (electrovalve with pressure sensor)
  • Possibility to drive the first direct current valves by means of a high voltage modulator circuit or through a bridge rectifier (integrated)
  • Output employable for the control of the second stage (intermittent pilot system), for the control of auxiliary fans or acting as a NO auxiliary contact (this contact is not isolated from the main supply voltage by reinforced isolation, therefore it not suitable to control SELV circuits – Safety Extra Low Voltage, e.g. 24V)
  • inbuilt ignition device completely of solid state design, highly efficient and equipped with a EMC filter-suppressor Possibility of connecting a resistor (100 ÷ 470 Kohm) in series to the lockout signal output in order to prevent the controller damage in case the lockout button connections are inverted by chance with the lockout signal connections
  • Connectivity
  • to a user interface module with diagnostic and parameters setting functions
  • or to sensor for the measurement of the flow and/or temperature of the air with safety shutdown or lockout.
  • or to sensor for the measurement of the gas pressure and adjustment (VCMxx * S BRAHMA valve)
  • or to adapter for the control of the brushless motors (i.e. BRAHMA B-FAN) and of the rotations with safety shutdown or lockout
  • Possibility to be connected to an infrared receiver for wireless control of the device (i.e., decorative fireplaces), in accordance with guidance B12 of the European Gas Appliance Directive 2009/142/EC (ex. 90/396/EEC)
  • Flame detection using the rectification property of the flame (with electrode probe or by detecting of UV emissions with photodiode FD.., only for gas appliances)
  • detecting visible light (with photo-sensors types FT, FC .. or by detecting of UV emissions with photodiode FD.., only for oil appliances)
  • Electrical service life at max. declared loading >250.000 operations
  • without burner output limits (times and working function must be suitable to the application in the project engineering phase of the same)
  • Direct ignition of the burner or ignition by means of an intermittent pilot
  • Multiple ignition attempts. In the standard mode, lockout condition with no flame detected at the end of safety time. Upon request, with option Ynn, it’s possible to set nn number of recycle attempts before lockout.
  • Possibility to be connected to phase-phase power supply systems.
