EM.1.1 GENERAL CHARACTERISTICS OF THE NON-

REGENERATIVE POWER SUPPLIES

IMPORTANT NOTE: PS-25A and PS-65A power supplies admit a mains

voltage of up to 460 Vac. The rest of their characteristics, connectors and

so forth of previous PS-25 and PS-65 are identical.

See appendix D for compatibility with the drives.
