Introduction
The 300 Series amplifiers are second generation products designed for low cost and high
performance. They can be mounted on chassis or p.c. boards and operate from 16 to 160
volt single-output DC power supplies. A wide range of inductive loads can be driven:
64 uH to 50 mH depending on model and supply voltage.
All units feature fully differential inputs for the control, or reference voltage. Enable
inputs for output control, a status output, and a current monitor signal ease system
interfacing.
The 22 kHz. PWM switching frequency eliminates audible noise from motor windings
and fast rise and fall times give high efficiency.
A Eurocard mount is available for 3U x 220 mm. rack mounting applications. A header
socket with plug-in components makes it easy to change compensation components for
different loads.
The amplifier is protected against over-temperature, over-voltage and under-voltage, and
output short circuits.
Getting Started
To install the amplifier you will need a control, or reference voltage, a power supply, and
a load. The reference voltage can be from something as simple as a potentiometer, or as
complex as a digital control system. The power supply can be supplied by the user, or
ordered from Copley Controls along with the amplifier to create a complete amplifier
subsystem. Loads are usually motors, but magnet coils, inductors, or other non-motor
loads can also be driven.
The amplifier is typically used as a voltage-to-current converter. ±10V reference signals
will drive the amplifier's peak rated current to the load in the 'flat-gain' mode. If a
tachometer is used, the amplifier is still operated as a voltage to current converter, but
the header components are changed to increase the gain of the servo preamplifier.
Use of the MB4 and Eurocard provides additional (optional) features such as voltage-
mode operation, armature-resistance(IR) compensation, PWM inputs, and output filters.
Eurocard mounts adapt the amplifiers to 3U subrack installations. Consult the factory for
Eurocard subrack systems.
