Roper Electronics specialise in the design, manufacture and repair of Automatic Voltage Regulators. Our main business is the manufacture of replacement AVR's for obsolete unit's and those for special applications. In a
ddition to our own range, we also stock a number of other manufacturers models in common use, including those from Newage/Markon, Contrology, Basler, Leroy Somer, Mecc-Alte and Marelli/Ansaldo.
We normally hold around 1000 units in stock at any one time for same day despatch, and custom built units can be supplied on short lead times.
Our range covers AVR's for small 2 pole generators up to Static Exciters with excitation currents in excess of 100 amps, as well as AVR's for use with high tension machines up to 11Kv. Our designs include both thyristor phase controlled and transistor pulse width modulated types with accessories such as Power Factor Controllers and Diode Failure Indicators. We can also supply AVR's for DC generators.
Other spare parts associated with generators, ie Paralleling C/T's, Rotating Diodes, Power Resistors/Rheostats and Volts Trim Potentiometers are also held in stock.
Most other manufacturers AVR's can be repaired if not encapsulated, and a service exchange facility can be provided with certain models.
With many years of experience in AVR's and generators, and in particular ECC/ECL, we are able to give advice and assistance for any technical problems which may be encountered.
