Signal Reference Grids (SRG)
ERICO Signal Reference Grids (SRGâ€™s) provide a low impedance equipotential plane to protect sensitive electronic equipment from transients. Because typical signal voltages are quite low, equipment can be very sensitive to transient noise.
- Pre-engineered welded grid of copper strips reduces voltage differences between interconnected electronic equipment
- An effective SRG has many conductors creating a very low impedance to noise at all relevant frequencies (DC to 100MHz). The multiple paths within the SRG allow any noise currents to divide at each intersection which reduces voltage drop
- Welded connections do not deteriorate, corrode or loosen with time
- Can be easily field-welded to suit any size computer room
- Complies with IEEE Standard 1100-1992, and is UL Listed
SRGâ€™s can be used for proper grounding and bonding of sensitive electronic systems, such as telecommunications, RF and computer installations.
