Field Mod for Replacing Power Supplies on Dual-PS VS2.5 Transmitters
Replacing UG69 and NAPS53 with UG132 and NAPS58A on VS2.5 transmitters with 2 Power Supplies
The original UG69 power supply modules are no longer available, and the UG132 modules are the replacement. The field modification kit (Nautel Part # 211-5112) provides all the required parts to complete the upgrade. The upgrade requires both power supplies be replaced at the same time and should take about 3 hours to complete. Nautel recommends two people for moving the VS2.5 due to its weight.
