In Many of the industrial and custom specific applications , the DC power source is available as utility source catering to many of the load requirements. Dubas INVERTERS converts these DC power into a specified voltage and frequency high quality AC supply source. Inverters are critical equipments used in various industrial and commercial applications. Dubas manufacturers a wide range of inverters across the market segments. The major markets where dubas offers its inverters cover:

	Railways (onboard or under slung type)
	Industrial applications
	Telecom applications
	Defense applications
	Solar Inverters
	Wind Power Inverters

Product range
	1 KVA to 300 KVA in applicaitons specific configurations
	Applicaitons specific constructions
	IP 65/ underslung/ onboard models

The product specifications vary quite significantly based on the applications. Importantly, dubas has the capability to build systems to suit specific compliance to various standards, as well meet customer’s application specific requirements.


SALIENT FEATURES
	AdvancedTechnology
	Dubas offers fully digitally controlled systems using advance DSP controllers. All systems are built with IGBT based PWM technique with advanced features for performance and reliability

	Wide Input Range
	System can be offered to handle wide input DC voltage variations to accommodate particular application.

	Pure Sinusoidal Output
	The system employs predictive waveform control technique, providing pure sinusoidal output with very low harmonic distortions and capability to handle non-linear loads.

	Excellent Transient Characteristics
	Dubas inverters provide excellent transient characteristics with maximum transients of + 5% and capability to recover to 97% in less than 5 msec.

	High Efficiency
	The systems are highly efficient and can achieve upto 96% efficiency depending on ratings and specifications. This allows the user to reduce the overall energy bills and reduce the overall heat handling requirements.

	Metering
	The standard systems employ touch pad for monitoring and diagnostics. All essential parameters are displayed alpha numerically. Scrolling facility is provided for user convenient. The system can also be provided with LED indications for specific user requirements. RS 232 computer interface is provided. Remote monitoring facility is provided as optional.

	Protections
	System comes with all essential switchgears like input DC breakers, output MCB / MCCBs. System is electronically protected against short circuits. Other protections like high temperature, DC low or DC high, output low or output high etc. come as standard protections in the system.
