The converter grade thyristor range extends upto 4350Amps with PIV upto 2800V incorporating standard packages of 14" unf stud in to hat range to 3"in capsule type. The inverter range is divided into two distinct types. One meant for standard low frequency inverter upto 4350 amps and 2800 volts and the other for high frequency applications such as induction heating and high frequency welding. The high frequency range has thyristors upto 1200 amps with voltages upto 2000 volts., 'turn off' times as low as 10 microsecs.

Starting with the supply of diodes for traction application, Hirect now caters to wide range of rectifiers for rolling stock application. High power electric locomotive, AC Electrical Multiple Units are powered by Hirect̢۪s on-board or under slung rectifiers. Hirect rectifiers are also installed on board Diesel locomotives and Diesel-Electric Multiple Units. Rectifiers for special purpose like OHE cars, Mobile Maintenance Units, Accidents Relief vans etc. are also catered. On-board Installation and Under-carriage slung version of rectifier sets are manufactured by highly trained work force and specially created infrastructure for a high degree of reliability in critical traction application.

The modules package concept has now gained acceptance as it offers compact and easy to handle designs. The semiconductor junctions are electrically isolated from the base allowing common heatsinks and compact designs. The insulating materials used between chip and base is carefully chosen so that the impedance is minimised. The Hirect range extends upto 350 amps and 2200 volts and is available in Diode-Diode, Diode-Thyristor and Thyristor-Thyristor configurations

HIRECT has developed specialized power electronic equipments for a range of applications. Thyristor control constant voltage and constant current power supply are used by R & D organizations like BARC, CAT, IPR etc. Constant Current Regulators are being supplied for Airport runway lighting. These are used for guidance during aircraft landing and take off at civil airports as well as air force stations. HIRECT systems are used for Naval frigates and submarines on high sea or patrol vessels on coast guard duty.

The power Diodes available from Hirect Include Standard Rectifier diodes starting from 6Amps to 6000Amp It(av), with voltages upto 4800V(piv). These devices are offered in a variety of packages starting from M6 stud in top hat range to 3" in capsule types. In addition to rectifier diodes, a number of fast recovery diodes and other special devices with avalanche characteristics are available

Power Supply for Electrostatic Precipitator Environmental protection concerns take centre stage today when it comes to fossil-fired power stations and particulate polluting industries. Improved efficiency and enhanced pollution control not only helps to get closer to the objective of a clean environment but also helps industries save valuable raw material going waste. Hirect Power Supplies for electrostatic precipitators with their particularly high efficiency and control leads the way towards clean Environment.

DC power Systems for Electrochemical Plants like, Potassium & Sodium Chlorate, Soda-ash, Caustic chlorine Production, Copper, Aluminium, Zinc refining all require modest voltage and high DC current. DC power is also required in other industrial process like hydrogenation, electrolysis, chlorination. Such continuous process industries look for a reliable, economical and trouble free form of DC power supply system. Hirect offers a complete range of rectifier equipment of all such applications and provides engineering, design and technical support in choosing the right solution equipment.

With the Indian Railways introducing three phase drive systems in electric locomotives and electric multiple units, Hirect also joined hands with CLW to become a partner for the manufacture of static converter for locomotives with three phase drive systems. with the absorption of technology, Hirect has become an indigenoussource for auxiliary converter and other panels required in this locomotive. Hirect is the major supplier of 25kVA inverters for AC coaches. The under slung Inverters are built on Technical known-how from our collaborators. It offers unique features like Natural cooling. AC Coach Inverter 25kVA. To keep pace with new technology. Hirect has entered into foreign technical tie-up for static converter for replacement of rotary arno converters of Electric locomotives manufactured and operated by the Indian Railways, A large number of 180kVA converters have been manufactured and installed. Hirect also offers 3 x 100kVA converters for the three phase electric locomotives.

To obtain the optimum level of protection under varying conditions, it is necessary to vary the impressed current continuously so as to maintain a constant level of protective potential at the structure. This continuous monitoring and control can be achieved by providing an automatic control for the cathodic protection system. HIRECT offers several types of TRU which are designed, manufactured and tested under strict quality assurance system to achieve highest quality standards.
