As the maximum output voltage of each amplifier is 100 V, the maximum current in each
channel is as shown:

The amplifier digitises the amplified signal prior to transmission.
Caution: the amplifier contains components that are very sensitive to
static and should be handled carefully. Before removing the amplifier,
turn off the source to prevent voltage build-up on the feed-through pins.
Before fitting the amplifier back on, short the ten feed-through pins to the
collector housing. Only when the amplifier has been refitted and
connected is it safe to switch the source back on.
Caution: never touch or attempt to clean any of the components inside the
amplifier, as this will result in contamination. Such contamination may
produce small tracking currents that could have a serious affect on
performance.
ELECTROMAGNET SUPPLY
The electromagnet power supply is located directly underneath the electromagnet and is
mounted within the electromagnet support. The unit is powered from the mains circuit. It
contains a raw DC supply and a programmable DC-DC converter under the control of the system
controller.
MAINS DISTRIBUTION
The power supply for the IsoPrime100 is provided by a single IEC connector located at the rear
of the instrument on the left hand side. This power input is connected to an IEC distribution
block mounted on the rear panel. Connection leads from this block provide power to the various
electronic units fitted to the instrument.
