Description
The LX Series of brushless servo drives is the latest in analog amplifier design from
Emerson EMC. The wide input voltage range and compact dimensions make it one of
the most versatile amplifiers available.
There are three amplifiers in the LX Series; the LX-400 (4.0 amps of continuous output
current), the LX-700 (7.0 amps of continuous output current) and the LX-1100 (10.9
amps of continuous output current). All three amplifiers have the same physical
dimensions.
Each LX Amplifier is matched with the proven reliable DX Brushless Servo motors.
When correctly matched, the LX Amplifier and DX Motor combinations offer continuous
torque output ratings of from 10 to 100 lb.-in.
The amplifiers incorporate pulse width modulated (PWM) design to provide efficient
power conversion. Sine wave commutation of the motor results in smooth rotation
across the full range of speed.
All LX Amplifiers are designed with their own power supply, heat sink, shunt resistor and
fan (when needed). This allows for simple installation and expansion.
