12 BSVT Introduction &
Configurations
12.1 Introduction
Since mid 2010 a new and higher integrated VT system is provided for all NMR applications.
The so called BSVT (Bruker Smart Variable Temperature System) replaces all former
standalone BVT3000 (Standard, MAS, BEST) and BSMS integrated BVT3200 variants. By
using a modular BSMS/2 and AV4 BSMS integrated concept all BVT variants and also former
pneumatic units like PNK3, PNK3S and PNK5 as well as the SLCB/2 and SLCB/3 boards are
replaced by the newer Sensor & Pneumatics Board (SPB) and the Variable Power Supply
Board (VPSB). The adaptation of the various probes and temperature control accessory
interfaces is realized with smartVT interfaces (also named VTAdapters). This digital interface
has also been introduced for other new digital sensors (e.g. digital liquid nitrogen level
sensor).
With the introduction of the AVANCE NEO Spectrometer generation, the VPSB is replaced by
the VPSB-DC. This version of the Variable Power Supply no longer requires an AC power
inlet, it is powered by the system AC/DC converter PSM-48V via BSMS Backplane. The
VPSB-DC is available in two power classes, the standard VPSB-DC with a total of 280 W
heater power shared on two channels. The extended version VPSB-DC-E provides a total of
530 W. Thereof 500 W may be diverted to channel 1 which also provides double the output
voltage.
