Purchasing

The trainer shown in Figure 1 is available in kit form.

  • The kit does not include the recommended wire ferrules and the UL 508A compliant white-with-blue stripe wire for ground signals.

  • A bench power supply (not included) is required to supply 24 VDC (recommend a current limited supply with up to 1 A capacity).
