The Remote Power Supply (RPS) system designed for MRI Series features Silent Source™. This technology is engineered to meet the stringent requirements of the MRI room, including reduction of Electromagnetic Interference (EMI).
Our RPS houses low-wattage drivers that require smaller filters, which produce less noise and are less expensive than traditional larger filters. All filters are also contained in this specially-designed enclosure. The 0-10V dimming circuit, which runs from the RPS to the control room outside the MRI room, does not require a filter.
Electrical devices can radiate and conduct electrical noise to other electronics, especially those designed to sense electrical signals. The lighting fixtures are identified as a source of radio frequency (RF) noise, creating interference with other sensitive equipment in the room or artifacts in the scans. For over a decade, Military Standards have been used to determine whether a luminaire operates within safe levels of Electromagnetic Interference in rooms such as surgical suites and imaging suites.
This standard relates back to aircraft and ships as the equipment is fixed in place (as in an MRI room), and the testing has to be within one meter of the device. This testing correlates the closest with what’s happening in these sensitive healthcare environments. If the luminaires can pass these testing requirements, it ensures that they will perform effectively in an MRI suite.
Information
For Linears – Target Total Luminaire Lumens, calculate by multiplying the original length by your desired lumen value. For example, if you want 800 lumens, multiply 800 × 4 (original length). Target Total Luminaire Lumens input would be 3200.
For optimal accuracy, always use a maximum length of 4ft. Anything beyond this includes only one light source. Note: Direct/Indirect scales proportionally and cannot be adjusted separately.
