PST/PSX Series Unregulated Power Supplies for PWM Servo Amplifiers FEATURES • Linear, unregulated power for PWM servo amplifiers. • Power, Mounting, and Cooling for 1~6 amplifiers • Optional fan-bar holds three 3.15” fans. DESCRIPTION • PST Models utilize an internal toroidal transformer 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 1-6 servo amplifiers. • PSX Models require an external transformer ( single or 3 phase ) • Thermal circuit breakers on AC power inputs eliminate inrush tripping at power on, permit fast reset in field. • Screw-terminal connections for mains wiring and motor power connections. THE OEM ADVANTAGE • Add amplifiers for complete drive subsystem. • Small footprint ( 7” X 11.5” ) • Dual AC-voltage models for OEM flexibility when shipping to international markets 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 750W output rating of the PST models (630W 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 1500W. The PSX series require either single or three-phase isolation transformers and incorporate extra capacitance internally. Model PST-075 and PST-150 provide +75VDC and +150VDC respectively for powering Copley Controls Corp. amplifiers that operate from +24 to +90VDC, and +24 to +180VDC. When utilizing lower voltage amplifiers such as Models 403, 405, 503, and 505 that operate from +18 to +55VDC, Model PST-040-13-DP supplying +40VDC is available. , PEM fasteners on top plate provide easy mounting of 1 to 6 amplifiers in a 7.0 X 11.5 in. footprint. An optional fanbar mounts three high efficiency 3.15” fans for direct, forced-air cooling when required. An optional extension plate adapts the larger amplifiers (Models 513 and 5xx1 series), increasing the footprint to 9.35” X 11.5”. Standard PST models operate from USA standard mains (120VAC at 60Hz) and output 75 or 150VDC with a 750W rating. For international power operation, PST-DP models offer switchselection of mains voltages: 115/230VAC at 50/60Hz in three output voltages. 261
