Steel Grid Element Resistors
SKU: EPH
Steel grid element resistors (Type EPH-S) are made of heat-resistant steel. The resistance value of the individual elements are temperature-dependent and the temperature coefficient is higher than classic wire-wound power resistors, Type ALW, however much smaller than the cast resistors. The design of these power resistors is a derivative of the Türk + Hillinger plate heater, Type EPH, which is designed with heating capacities of up to one (1) megawatt for applications that require high electrical performance and ruggedness.
WHAT ARE STEEL GRID ELEMENT RESISTORS TYPE EPH?
Key characteristics:
Material and behaviour: They use heat-resistant steel, so their resistance value changes with temperature. The temperature coefficient sits higher than that of classic wire-wound power resistors (such as Turk & Hillinger’s own ALW type) but remains much lower than that of cast resistors.
Energy handling: Stock versions absorb between 50 and 70 kJ (kilojoules) of energy for a 300 K temperature rise in still air, making them suitable for high-pulse or braking duties.
Applications: Engineers commonly use them as braking resistors, load resistors, chopper resistors, starting resistors, current limiters, or for other heavy-duty electrical duties (for example, in drives, energy dissipation, or grid stabilisation). Their sturdy construction suits harsh industrial environments where reliability and high power handling matter.
In short, these EPH resistors provide a tough, high-capacity alternative to wire-wound types when you need something that can take significant electrical and thermal stress while maintaining consistent performance.
ADVANTAGES OF STEEL GRID ELEMENT RESISTORS TYPE EPH:
In addition to the classic application as a heating or chopper resistance, the design can also be used for the following resistances: current limiting, discharge, as crow bar, FRT, LVRT, emergency stop, load, starting, permanent, braking or filter resistance.
BESPOKE DESIGN TO MEET YOUR NEEDS:
The energy absorption capacity of the Type EPH-S, available from inventory, is between 50 and 70 kJ (= kWs) at a temperature increase of 300°K at dormant air. The average thermal time constant is 100 seconds. By varying different individual steel grid resistance elements, it provides and covers a wide range of benefits, energy absorption and ohm values.
