– Compatibility & Integration
The 81552SM integrates directly into HP/Agilent mainframe platforms: 8153A, 8163A, 8163B, 8164, and 8166 series. Power requirements are managed by the host mainframe. North American installations typically require 20 A, 90–130 Vac, 60 Hz ±3 Hz; international installations require 10 A, 180–260 Vac, 50 Hz ±3 Hz. Dedicated power sources are recommended to prevent mainframe overload.
