Power Systems & Controls:

Frequency Converters | UPS Systems | Tactical Enclosures

Power Systems & Controls Inc., (PS&C), is an American manufacturer with World Headquarters in Richmond, Virginia, since 1965.  We have been manufacturing Power Products and Tactical Enclosures in support of the United States Government and Industrial / Commercial customers.  Our manufactured power quality products include Uninterruptible Power Supplies, Frequency Converters, and Power Factor Correction products.  In addition to our Power Quality products, we manufacture Enclosure and Shelter solutions used in many applications worldwide.

Along with our Uninterruptible Power Supply Systems and Frequency Converters, PS&C builds many other Power Conditioning products.  These products include Motor Generator Sets, Power Factor Correction, Voltage Regulators, and Grid Stabilizers to mention a few.  Similar to our converters, (Rotary Frequency Converter and Static Frequency Converter), we offer rotary and solid state versions.

Frequency Converters:

There are 2 typologies for Frequency ConvertersRotary Frequency Converters are manufactured using a Motor Generator set.  Static Frequency Converters are manufactured with solid state electronics and semi-conductors . Although each topology has its own advantages, they can be used interchangeably.  The Rotary Frequency Converters is a harsh environment industrial machine.  Whereas, the Static Frequency Converters are designed and built for non-industrial and less harsh applications.

Another hybrid product built is a converter that will maintain power output when the utility is no longer available.  This converter is also a UPS, called a Frequency Converter UPS.  Lastly, there is an option for the Frequency Converter to clean up a non-stable input frequency.  These type machines can accept a poor frequency range on the input and produce a stable output.  The Dynamic Frequency Regulator is a great solution to produce regulated frequency and voltage.  This unit allows for a very unstable utility, while producing clean electric power to your equipment.

Uninterruptible Power Supply:

An Uninterruptible Power Supply (UPS) only has one job.  Keep the equipment power on when the utility power is no longer active.  When a power disturbance occurs, it is critical for the Uninterruptible Power Supply to be in working condition and avoiding an interruption in power.  The uninterruptible power supply will continue to provide electricity to your equipment until Emergency power is available.  PS&C offers Hybrid Rotary Uninterruptible Power Supply and Static Uninterruptible Power Supply systems to our customers.  This choice in the type of UPS is not common as almost every other uninterruptible power supply manufacturer only builds one topology, which inherently takes your decision away.

Tactical Enclosures

Our Enclosure and Shelter solutions include SCIF’s, Modular Office Space, Portable Data Centers, Modular Operations Center, Forced Entry Ballistic Reinforced (FEBR), Hardened Alternate Tactical Shelter (HATS), and custom Tempest & Hemp Structures.  Our enclosures are Portable, Modular, and Tactical solutions.  This allows our products to be inherently expandable systems.

Power Systems & Controls developed our Sensitive Compartmented Information Facility (SCIF) for critical customer application and the U.S. Intelligence community, for data protection.  These facilities are protected space used to process Sensitive Compartmented Information (SCI) concerning intelligence sources, methods, or analytical processes.  PS&C’s portable Sensitive Compartmented Information Facilities (SCIF) are manufactured to the highest standards required by the United States Government.

What makes Power Systems & Controls (PS&C) unique is our ability to integrate our power quality systems into our Enclosure and Shelters solutions.  This offers our customers a range of special application high quality products.  With 1000’s of machines located worldwide, PS&C is the obvious choice for Power and Shelter products.

Our commitment to quality and our customers ensures we manufacture the highest quality products each and every time.
