STP-PWR-7005

Power supply for stepping systems

The power supply plays a dual role: it supplies the main power to the motors as well as the power to optically-isolated digital inputs.

The motor power is typically provided by a linear non-regulated power supply.

The SureStep™ SSTP-PWR-7005 power supply has a 70VDC@5A (when fully loaded, 86.5 VDC unloaded) output to supply power to the motor via the drive. Also, the digital interface between the drive and the controller/ indexer should be powered by the isolated +5 VDC (500 mA max) regulated output. The motor power and the digital interface power are isolated since the motor power source is extremely "noisy" when loaded. Using the motor power for the interface might lead to false pulse commands thereby creating undesired system movement.

One SureStep™ power supply can provide both motor power and interface power to a least two complete SureStep™ drive/motor combinations.
