RTA Pavia SAC25 ministepping drive

Introduction:

•     High efficiency bipolar chopper circuit.
•     Protection from motor short circuit, overtemperature and overvoltage.
•     400 to 4000 steps/rev for smooth running at low speeds.
•     Low power upto 6 Amps @ 65V. Drives 23 & 34 frame motors.
•     LEDs for supply voltage, thermal protection, overvoltage and motor fault.
•     Optocoupled signal inputs & outputs for protection.
•     Electronic damping reduces low speed resonance.
•     Suitable for two phase motors, 4, 6 or 8 leads.
•     Powered by simple transformer AC power supply.
•     Compatible with 5V TTL indexers.
