DC Servo Amplifiers

TRM has developed an innovative new DC Servo amplifier which proves to be a breakthrough in amplifier technology. Utilizing the latest in electronic techniques, this compact current mode amplifier is capable of driving brushed DC Servo motors continuously at 80 volts and from 5 to 20 amps depending on the model. The amplifier is built onto a large heatsink and is enclosed in a case that also acts as a mounting bracket. Connections are made via two connectors, one for the low voltage signals and the other for the higher voltage motor supply and drive connections. The DC analogue amplifier has all the major features expected: Gain, Offset, Current limit control, Enable and Error indicators and a ± 10 volt input signal range. The opto-isolated amplifier enable signal is capable of being driven high or low depending on the users application.
