• Magnet side kit contains Voltage Regulator Box, Mega Switch, RRX, cables and base plate.
It is mounted on the left side of the magnet through insulating board, and a ground wire
is connected between base plate and system cabinet.

Box regulates the DC power from DCPS for Mega SW & RRX. Mega SW combines the
function of 8ch switch, MUX, UTNS and receiver. RRX used in SV system is 8 channels.
• Mega Switch select different input RF signal, and amplifies them according to R1 value,
and transform the center frequency of RF signal to 16MHz, then send them to RRX. RRX
converts the analog RF signal to digital signal and transfer them to VRF in ICN by optical
fiber.
