Electrical Specifications
The amplifier is a brushless type trans-conductance linear amplifier for sinusoidal commutation. The amplifier
outputs a motor current proportional to the command signal input.
DC Supply Voltage: 15-40 VDC
In order to run the AMP-43640 in the range of 15-20 VDC, the
ISCNTL – Isolate Controller Power option must be ordered
Continuous Current 1.0 Amps
Peak Current (per axis) 2.0 Amps
Amplifier gain: 0.2 A/V
Power output (per channel): 20 W (see section below)
Total max. power output: 80 W (assuming proper thermal mounting and heat
dissipation)
The amplifier has built in thermal protection which will cause the amplifier to be disabled until the temperature of
the transistors falls below the threshold.
