SD-700 STEPPING MOTOR DRIVER

A MOTOR DRIVER FOR 3 STEPPING MOTORS, WITH POWER SUPPLY
Introduction
The SD-700 is a fully featured miniature stepping motor driver for up to three motors, designed especially for OEM applications. Its high reliability, small size and low heat dissipation makes the SD-700 a perfect solution for driving small bipolar stepping motors at currents of up to 2.3 Amps per phase, in Full Step or Half Step modes.

Features

  Drives 3 motors - taking up only 70 x 30 x 206 mm (2.75 x 1.18 x 8.1 Inches).
  Optically isolated inputs for high noise immunity.
  Built-in power supply for motor and logic - only power transformer needed.
  STEP, DIRECTION, FULL/HALF STEP, ENABLE control inputs.
  Current limiting resistor for each drive.
  Interfaced to standard TTL level signals.
  Operating software for PC available (for up to 6 motors).
  Low-cost - only $110 per motor.
  Single, dual and triple motor drivers available.

Technical Specifications
  AC input voltage: 12 - 24 Vac (rms).
  DC input voltage (if power supply not used): 14 - 32 Vdc (motors) + 5 Vdc (logic).
  Transformer current : sum of phase currents x 1.5.
(example: 3 motors of 1 Amp/phase each, will require a 4.5 Amp transformer).
  Isolation: all control inputs are optically isolated.
  Input levels: TTL compatible level.
  Input current: High - 5 mA, Low - 0 mA.
  Input levels: High - 3.5 - 5.5 V, Low - 0 - 2 V.
  Chopping frequency: 18 or 25 kHz. (please specify).
  Stepping rate: up to 20,000 Steps/Sec.
  Operating Temperature: -20 to +50C.
  Operating Humidity: 5% - 95%.
 Physical dimensions (H x W x L):
- One motor driver with power supply: 30 mm x 70 mm x 106 mm.
- Two motor driver with power supply: 30 mm x 70 mm x 156 mm.
- Three motor driver with power supply: 30 mm x 70 mm x 206 m.
- Above drivers without power supply (DC operated): reduce 30 mm from length.
