Cape Town-based Rhomberg manufactures and distributes power surge protectors that can withstand surges of up to 300 kA.
Originally designed by McAllister Technologies of Pietermaritzburg, the Rhomberg Hi-Power range of surge protectors safeguards sensitive commercial and household electronic equipment and industrial process control systems from the destructive effect of lightning surges, industrial switching, and electrostatic discharge and radio frequency interference.
"We did extensive research before introducing this range and found there to be an enthusiastic response among our customers, particularly in lightning-prone areas in the northern parts of South Africa as well as overseas," said John MacDonald, managing director of Rhomberg.
One of the key features of the Rhomberg Hi-Power surge protectors is the use of silicon carbide components as opposed to the more conventionally used metal oxide varistors. They operate within an extremely short response time (less than one microsecond) and have a significant advantage over other makes by continuing to operate efficiently, even after repetitive conduction.
There are as many as 40 different types in the standard range of Rhomberg Hi-Power surge protectors, ranging in price from hundreds to tens of thousands of rands. Specials are available to meet customers' specific demands. Rhomberg will undertake on-site investigations on premises to determine surge protection requirements.
