PS&C Offers Many Solutions

In our thirty years of providing products and services to critical power customers, PS&C has observed many changes in the industry. Obviously, the focus for years was on large Data Centers and Telecommunication facilities. The power demands of these applications were considerable and the importance of clean, uninterrupted electrical power was obvious. Over twenty years later, in addition to the large data centers, we now see critical operations being decentralized in the Office, Test & Research Labs, and Manufacturing locations. Quite often power quality is an unexpected problem. In response to this need, we can perform an analysis of a customer’s electrical system to determine the exact causes of their power problems.

Also in response to the smaller electrical loads which require maximum reliability, we now offer the Series MC from 30kVA up to 250kVA. This RUPS, like our larger Series XC, is a true online design. While it continuously produces clean, isolated power from its synchronous generator, the electrical load is provided with a perfect sine wave. When a disturbance or outage is long enough to require the UPS to draw power from the battery, nothing such as a switch or transfer needs to occur. We believe that this is the ultimate in power protection as do all of our satisfied customers.

Power Systems & Controls has a state of the art production and test facility located in Richmond, VA allowing for easy access to Washington, DC and the east coast. PS&C has the unique ability to support both static (solid-state) and rotary (motor generator) UPS, frequency converter, and power conditioning requirements as we are one of the few companies in the world that manufactures both types of technology. Power Systems & Controls is an employee owned company and has a long history of successfully supporting mission critical applications across the world. PS&C – The Power Is On!

PS&C UPS Reliability

The words “simple” and “reliable” are two words often exploited in today’s commercial environment. However, when applied to PS&C’s newest product, the Series MC hybrid rotary UPS, these terms are more than accurate. Available in modules ranging from 30 to 200kVA, the Series MC is extremely easy to operate. The touch screen control panel allows for easy operation and makes complicated and/or confusing operating instructions a thing of the past. To provide UPS protection for the critical load, the operator simply pushes the button labeled “UPS”. To place the load on utility and shut down the Series MC, just pushing the “Bypass” button transfers the load without any interruption.

The Series MC’s claim of superior reliability is backed by 30 years of rotary UPS experience and technology. PS&C uses as an output device, a time proven synchronous generator which is driven by a highly efficient inverted rated induction motor. A highly dependable, conservatively rated induction motor drive provides the power to the induction motors and all Series MC operations are controlled by PLC control technology. With its ease of operation and 30 years of Rotary UPS experience behind its design, you just cant go wrong with PS&C.

Ring Bus Load Management

PS&C recently shipped an UPS system with innovative load management. This innovation was part of the control logic installed in a ring bus UPS system shipped by PS&C. Previously, a ring bus was configured with “X” modules with “X-N” modules required to support the total load. When the number of modules removed (for any reason) from the ring bus exceeds “N”, the ring bus logic was required to split the ring bus. Splitting the ring bus puts part of the load on utility, while the remainder remains on the UPS. This happened because the PLC logic must make a blind decision to split the ring bud whenever the number of modules supporting the load is less than “X-N”.

This condition has been improved by the addition of PS&C’s optional “Intelligent Load Management System” for ring bus applications. By measuring the power required by each load node on the ring bus and measuring the output power of each module, the PLC has a complete picture of available power and total load. With a complete picture the PLC can determine the actual number of UPS modules required to support the actual load. It is not possible in a ring bus system to keep clean UPS power to the User’s load under more scenarios due to PS&C’s “Intelligent Load Management System”.

Ring Bus Ideal for High Tech Manufacturing

PS&C is in the business of solving our customer’s problems. The hi-tech process manufacturing industry has unique problems that demand the unique solutions provided by PS&C’s Ring Bus system. Our latest ring bus site is configured with three (3) 1000kVA Hybrid Rotary UPS Reverse Transfer Modules.

No Tolerance for Down Time…

In a typical process application, like microprocessor chip production, a one second power interruption costs over $1 million in material alone! All conventional single failure points were eliminated (ie. single output, single bypass, common bus).

Expandability for Future Growth…

The process industry like many businesses is very unpredictable. This industry; however, has been experiencing explosive growth, especially the chip manufacturing sector. A system was needed with infinite growth possibilities. The ring expansion link will permit isolation for a future section to be added without shutting down the ring bus switchboard (no down time during the upgrade).

Flexibility…

Loads change often, and maintenance must be performed at regular intervals without effecting process output. The ring bus distribution system has multiple outputs allowing for separation of the load by command and multiple bypasses for load recovery.

Loads Are Very Non-Linear…

Loads consist of many very precise variable speed drives, and process computers which can feedback as high as 70% current THD to the source (UPS system). The low impedance source provided by the PS&C output generators is naturally suited for this type of demanding load.

Fast Delivery…

The company with the best product, and the ability to get it to market the fastest, wins in the high tech marketplace. PS&C was able to design, manufacture, test, and ship the entire system in only 12 weeks.

PS&C Constantly Improving

 

The Series XC contains a six pulse rectifier/battery charger. Previous generation rectifier controls were seldom balanced, seldom stable with respect to firing angles, and were not designed to minimize harmonic content of the input current. This lack of precision and control resulted in distribution of harmonics whose amplitudes were not predictable.

Therefore, PS&C has developed a new Digital Rectifier Control Board to address this phenomenon. The new board eliminates all even harmonics and it makes the distribution of harmonics predictable. These two features alone would justify the design effort, but there is more. The Digital Rectifier Control Board easily maintains 1% regulation of the battery voltage and DC link, provides a timed current limit (walk-up), and accepts an input from an optional battery current limit board. In addition, it monitors the health of its power supplies the utility voltage, and has an upper voltage clamp to prevent excessive DC link voltages. The new Digital Rectifier Control Board is just one more example of our commitment to continually improve PS&C Products and Services.
