Power Factor Correction Capacitors

Benefits

Steelman Capacitors are proven to provide the benefits associated with top-quality power factor correction capacitors. Improved voltage, increased system capacity, and a reduction in line losses are the assured benefits of Steelman Capacitors. Of course, an improved power factor, which may result in a lower power bill, is guaranteed as well.

Quality

Steelman Capacitors are engineered for heavy-duty, trouble-free use. Steelman capacitors are built with components that meet or exceed industry standards. The result is an extended life expectancy and outstanding performance in harsh environments. Steelman offers three-phase capacitor cells that have a rated life of 150,000 hours, as well as a design of single-phase capacitors wired in a three-phase delta configuration. This allows replacement of just one phase instead of all three phases of a capacitor. Steelman capacitors are also UL Listed.

Options

An assortment of options provides for special requirements, convenient installation, and inspection.

1. Integral Contactor (/C) -an integral contactor is used to switch a fixed capacitor on & off when it cannot be switched by the motor starter. The most common situation that would require an Integral Contactor is where the motor does not have an across-the-line starter (i.e. open transition, reduced voltage starters). This situation also occurs when the motor is subject to reversing, plugging, or frequent starts; crane or elevator motors, or any motor where the load may drive the motor, or multi-speed motors. On these applications, the Capacitor should be installed on the distribution system ahead of the motor controller, and must not be switched with the load motors.
   
   
2. Integral Circuit Breakers (/CB) -when a Capacitor is installed on the main bus of a power system, a fused disconnect means is required. Steelman can supply an integral circuit breaker that will serve as the fused disconnect.
   
   
3. Internal Fusing (/F) -Internal fusing is a means to protect the "insides" of the capacitor. It will also take a capacitor off-line if there is a problem with the capacitor itself. This keeps problems from traveling up the power system. For example, if a non-fused capacitor is wired to the load-side of the motor starter, and it shorts out, the motor protection device will trip causing the motor to shut down. If the capacitor had been fused, the capacitor would have gone off-line but left the motor up and running.
   
   
4. Blown Fuse Indicator Lights (/FPL) - Blown fuse indicator lights make inspection easy. A quick visual check will let you know if all capacitors are on line.
   
   
5. Pigtails (/PT) - A four foot, four conductor SO cord allows installation without having to knock holes in the enclosure or remove the lid during installation.
   
   
6. Steelman Advantage (/SA) - This option uses higher-grade capacitors to extend the life expectancy of the unit. For more information click here.
   
   
7. Special Enclosures - Steelman will design enclosures based on size requirements, environmental conditions, or any special specifications, including stainless steel enclosures

Rotary Phase Converters

All Rotary Phase Conversion Systems have common components: (1) a three phase motor winding that acts as a generator to produce a three phase output from a single phase power source, and (2) a run capacitor section that provides for a more stable current and voltage condition when loads are applied. Some Rotary Phase Converters also have what is known as a "start circuit" which consists of start capacitors, a contactor, and a control relay. The "start circuit" is the most critical link in these Rotary Phase Converters, since if one of these components should fail, the "generator motor" will not get up to speed, resulting in damage to the generator winding and single phasing the load connections. Steelman Industries has taken this weak link out of the Rotary Phase Converter, by having Baldor Electric Company of Fort Smith, Arkansas, design a three phase "generator motor" that will start on single phase power without the necessity of a "start circuit". Other Rotary Phase Converter manufacturers use foreign brand motors and cut the shafts of the motors and add the "start circuit", thus modifying the motor to do something it was not designed to do, and requiring you to return the unit to the factory for repair. Warranty on Steelman's Baldor "generator" motor is covered by any of the several thousand Baldor warranty stations across the nation. If you should have a problem with your Steelman Rotary "generator motor", Steelman can get you in contact with a local electric motor repair shop, which will be able to assist you promptly.

Steelman utilizes top grade capacitors purchased directly from the capacitor manufacturer, while other competitors buy surplus capacitors that result in inconsistent inventory and quality. Steelman uses 480 Volt rated capacitors in its 240 Volt Rotary Phase Converters and 660 Volt rated capacitors in its 480 Volt Rotary Phase Converters. The voltage across the capacitors in Rotary Phase Converters will run 20 to 40 volts higher than the incoming voltage under no-load conditions. This higher voltage produces extra stress on capacitors that are rated for the incoming voltage. Using higher voltage capacitors greatly increases the life expectancy of these components and also results in a reduction of thermal losses making the Steelman Rotary Phase Converter more efficient and stronger in performance than other brands.

Unlike other competitors, Steelman manufactures its own enclosures and motor bases. Steelman's Rotary Phase Converter is built on a steel base, while other competitors require you to mount the generator motor.

Steelman's Rotary Phase Converter has simple connections and simple installation instructions for a successful operation. It comes with a 2 pole terminal block labeled for Single Phase input and a 3 pole terminal block labeled for three phase output. Other competitors have loose wires, requiring you to make your own connections.
