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 PM224 module is a MOSFET single amplifier. The PM21 is a dual
integrated circuit amplifier. The PS125 uses a heavy duty 160VA
toroidal
power transformer.
The PS125 is ideal for OEM applications, powered amplifiers, for
driving
precision servo motors, instrumentation and so on. The amplifiers are
short
circuit protected, and also have thermal protection, making these units
almost indestructible. Typical power bandwidth of the amplifiers is DC
to
25KHz. The amplifiers
all 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 any load. For
diferent
load requirements consult factory. The high voltage version can be
ordered
with an output voltage range of up to +/- 200V; consult factory for
details. For example, the PS125HV-140-224 has max. output voltage of
+/-170V and is thus able to output up to 120VRMS.
