Dubas Engineering Pvt. Ltd Hosur, Bangalore, Karnataka

DUBAS designs and manufactures Dynamic Reactive Power compensation systems for Traction Substations (TSS). The power factor of the substation suffers from dynamic load pattern due to a number of trains getting in and out of the substation power loop based on train movements. DRPCE is a dynamic PF and power quality improvement system, capable of both inductive and capacitive compensation instantaneously. Dubas’ DRPCE systems are based on dubas ePFC philosophy and is an IGBT based PWM current generator. DRPCE system is a hybrid combination of several ePFC panels and HT capacitor bank to reach desired compensation capacity. Dubas DRPCE systems are approved by RDSO and are in compliance to RDSO specifications. Dubas offers the DRPCE system on a turnkey basis including HT to LT conversion transformer, HT capacitor, Reactor and all protection systems along with Dubas range of IGBT based panels. FEATURES: IGBT based PWM current generator technique with DSP based digital control, seamlessly parallelable. Dynamic system to maintain input PF near unity irrespective of the load dynamics. Can be built to reach several MVAR ratings and offer most cost economic solution through Hybrid model in combination with existing / new HT capacitor banks. Compensates both Inductive and Capacitive reactive power. Avoids danger of over compensation and resonance. System is expandable by adding incremental rating panels in parallel with the existing DRPCE panels

Dubas designs and manufactures extensive range of DC systems Battery Chargers to suit both commercial and industrial applications.

Dubas designs and manufactures a wide range of UPS Systems for commercial and industrial applications. UPS has a very critical function of providing high quality power output, which should be fully isolated from input electrical and ground noises.

DUBAS designs and manufactures servo controlled stabilizers for meeting almost every application of Industry and commerce. Servo stabilizers are essential to stabilize the prevalent grid voltage variations which cause serious problems to user loads and operation continuity

dubas offers extensive range of solid stage frequency converters for various applications. These systems offer frequency conversion from a particular frequency to the required frequency depending on the application.

Power management is imperative for any industrial or commercial establishment big or small. Without good power management practices, companies could face problems of failed equipments, regulatory penalty and inefficient operations.
