Screw-terminal connections for mains wiring and motor power connections. THE OEM ADVANTAGE Add amplifiers for complete drive subsystem. Small footprint ( 7 X. ) Dual AC-voltage models for OEM flexibility when shipping to international markets DESCRIPTION PST/PSX models are linear, unregulated power supplies designed to be used with Copley Controls PWM servo amplifiers. They provide DC power, mounting, and (optional) cooling for - servo amplifiers. The small footprint takes advantage of the fact that multipleamplifier installations seldom operate at the maximum continuous power rating of each individual amplifier. Particularly in incremental motion applications, machine design commonly prevents simultaneous movement of all axes, and when motion occurs, it requires less than the amplifiers peak rating. This package was developed to put the largest possible transformer into the smallest package that would mount up to six amplifiers. The 70W output rating of the PST models (0W for dual-voltage PST-DP models) is sufficient to drive the majority of applications, given the varying duty cycles and power outputs of the mounted amplifiers. When higher power is required, the PSX models utilize external isolation transformers to increase unit power ratings to 00W. The PSX series require either single or three-phase isolation transformers and incorporate extra capacitance internally. Model PST-07 and PST-0 provide 7VDC and 0VDC respectively for powering Copley Controls Corp. amplifiers that operate from to 90VDC, and to 80VDC. When utilizing lower voltage amplifiers such as Models 0, 0, 0, and 0 that operate from 8 to VDC, Model PST-00--DP, supplying 0VDC is available. PEM fasteners on top plate provide easy mounting of to amplifiers in a 7.0 X. in. footprint. An optional fanbar mounts three high efficiency. fans for direct, forced-air cooling when required. An optional extension plate adapts the larger amplifiers (Models and xx series), increasing the footprint to 9. X.. Standard PST models operate from USA standard mains (0VAC at 0Hz) and output 7 or 0VDC with a 70W rating. For international power operation, PST-DP models offer switchselection of mains voltages: /0VAC at 0/0Hz in three output voltages.

2 APPLICATION INFORMATION PST MODELS These models employ internal toroidal transformers and connect directly to the mains. There is a thermal circuit breaker in the AC input circuit. This protects against external overloads, and internal failures, but permits the high inrush currents into the filter capacitor without false tripping. PSX MODELS These models have no internal transformers, and connect to the secondary windings of external isolation transformers. MODEL PSX- USES SINGLE-PHASE TRANSFORMERS, MODEL PSX- USES THREE-PHASE. EACH TYPE HAS INPUT THERMAL CIRCUIT BREAK- ERS THAT PROTECT AGAINST OVERLOADS AND PREVENT FALSE TRIPPING WITH INRUSH CURRENTS INTO THE FILTER CAPACITOR.
