Overview


PS Series Frequency Converter

Unitron’s PS-94 Series programmable AC power supply operates from any standard worldwide power source, and provides 50 Hz, 60 Hz or 400 Hz output power in various single-phase and three-phase configurations. The unique design of the low-power bench unit allows the user to independently select operational parameters, such as frequency and voltage, using a field-replaceable programming plug. This versatility makes the unit ideal for use in research laboratories and production line testing.

Unitron's PS series programmable power supply is available in a standard single unit power rating of 3.5 kVA. When higher output power is required the units may be paralleled to supply up to 40 kVA.

NOTES:
  1. Programming plug (PP Series) or parallel cable (PPC Series) required to determine output frequency and phase configuration.
  2. Two paralleled units require one programming parallel cable (PPC Series) only. Three or more paralleled units require a programming parallel box (PB Series) in addition to one programming parallel cable (PPC Series) for each unit. Paralleling for grid expansion up to 17.5 kVA only.
  3. Unit does not include circuit breaker.
  4. Requires one PC-P1 type parallel cable (PC Series) for each unit.
  5. Requires one PC-P3 type parallel cable (PC Series) for each unit. (Limit 3 units.)
  6. Portable power supply and distribution system.
  7. Two or more paralleled units require a paralleling control box (PCB Series) in addition to one paralleling box cable (PBC Series) and one interconnect power cable (IPC Series) for each unit. Paralleling for common output buss grid expansion (up to 17.5 kVA) or for N+1 redundancy/hot swap system configuration.
  8. Units meet EMI requirements per MIL-I-6181D.
  9. Other output frequency and voltage options available. Contact factory.
  10. Includes 100 msec. ride-through option.
  11. Unit input is 115V, 30-800Hz, single OR three phase.
