About the DM-150
The DM-150 is a model of 150-amp BRU-500 Servo Drive that was created by Reliance Electric. The drive could have also been mass-produced by Baldor Reliance or ABB depending on when its production years were. Because none of these manufacturers continue to support this drive, it may be a little difficult to find. AX Control, however, makes every effort to keep it stocked as a new surplus or refurbished drive. The DM-150 is a 3-Phase 170/340 VDC, 120/240 VAC, and 50/60Hz brushless servo drive module. Some relevant environmental ratings for this unit include:
- a bus voltage between 125-375 VDC but 325 VDC when it has a 230 VAC input
- an ambient temperature of roughly 0 to 50 degrees Celsius
- a weight of11.0 kg
- a command signal input that ranges between +/-10 VDC
- a continuous amperage of around 65A with a total peak amperage of 150A
- a maximum total wattage loss of 300 watts
- normal wattage loss is only around ½ that amount
The DM-150 is meant to be a device that offers control and power to an Electro-Craft type motor. The specific motors recommended for this drive are in the S-Series. They are the S-8500 and the S-6300.
