DRIVES FOR STEPPING MOTORS FOR ELECTRIC CYLINDERS SERIES ELEKTRO

6A - 140VDC DRIVE FOR STEPPING MOTORS, CODE 37D1442000

10A - 62VAC DRIVE FOR STEPPING MOTORS, CODE 37D1552000

These are two ministep bipolar chopper drives made by RTA S.r.l.

They come with a STEP & DIRECTION interface for piloting medium/

high-power two-stage STEPPING motors with four, six or eight terminals.

They consist of a board housed in a metal box, which does not require

external ventilation, and come with separate logic and power pull-out

screw connectors.

Drive code 37D1442000 is characterised by a voltage range up to

140VDC, compact dimensions and considerable operating flexibility.

This drive can control STEPPING motors with a nominal current up to 6A,

the perfect choice for medium-power applications requiring a DC supply.

Drive code 37D1552000 is characterised by a voltage range up to

62VAC, compact dimensions and considerable operating flexibility.

This drive can control STEPPING motors with a nominal current up to 10A,

the perfect choice for medium-power applications requiring an AC supply.
