LPA05 User Guide
LPA05
High frequency, high power, dc accurate, power amplifier
for laboratory and industrial applications.
Description
LPA05 is a wideband power amplifier with
40V peak voltage output
at 3A rms from dc to 500kHz. At lower output levels, the gain
extends beyond 1MHz. It uses an innovative balanced high
frequency design to give a slew rate of greater than 120V/us, while
maintaining dc accuracy and high reliability.
LPA05B is a higher current, lower voltage version capable of
delivering 5A rms from dc to 1MHz at
16V peak.
LPA05 is generally stable driving any load - resistive, capacitive or
inductive – but as with all high frequency amplifiers, care must be
taken when connecting to pure capacitive loads. An appropriate
resistor or inductor may be needed in series with the capacitive load
to minimise peaking in the frequency response or to prevent
spurious oscillation.
LPA05 is powered by a universal input power supply monitored by a
pair of indicators on the front panel. Internally the LPA05 is floating
from ground to minimise earth loops, but can be grounded by linking
the output 0V to earth via the 4mm connectors.
LPA05 is housed in a robust steel cabinet.
Do not obstruct the ventilation holes on the sides,
underneath or rear of the amplifier.
