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 (see
note) 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.
