The PS125 power amplifier series provide high quality power
amplifier in an economical and rugged construction. The unit has a
toroidal power transformer and linear rectifier unit mounted in a
heavy duty aluminum chassis that acts as the heat sink for the
power amplifier. The PS125 uses a heavy duty toroidal power
transformer. The PS125 is ideal for OEM applications, powered
amplifiers, for driving precision servo motors, instrumentation
and so on. The amplifier is short circuit protected, and also has
thermal protection, making these units almost indestructible.
Typical power bandwidth of the amplifiers is DC to 25KHz. The
amplifiers
have differential inputs that can be used with a unbalanced or
balanced source. An internal jumper selects between AC or DC
coupling. Typical harmonic distortion is 0.01% or less. Typical
load capability of the amplifiers is 8 Ohm, but the amps are
stable with most loads, resistive and capacitive. For different
load requirements consult factory.
