EDITOR'S NOTES

SpinZoneSmiley guy goes into battle

The green smiley guy has been appearing on our company-sponsored BattleBot named SpinZone, (the result of a design contest sponsored by Product Design and Development magazine). SpinZone was built by Christian Carlberg, who has several winning BattleBot designs to his credit. SpinZone entered its first battle recently and won the first round and advanced to the second round. Unfortunately, SpinZone was defeated in a brutal battle in the second round and sustained some damage. SpinZone is on the disabled list for now. We are hoping for a full recovery.

What is a Control Transformer?
by Carl Tolbert, Tech Support Specialist

A control transformer is an isolation transformer designed to provide a high degree of secondary voltage stability (regulation) during a brief period of overload condition (also know as "inrush current"). Control transformers are also known as: machine tool transformers, industrial control transformers, or control power transformers.

CPT transformersDesigned with PLCs in mind
With the advances of high-speed electronic trip devices in circuit breakers, low impedance devices, and fuses, safety conscious engineers and panel designers responsible for creating control systems have become increasingly aware of the phenomena of transformer inrush current. Inrush current, although unavoidable, can be limited with the deployment of high quality control transformers like the CPT series from AutomationDirect.

The CPT series of control transformers are specifically designed for high inrush applications requiring reliable output voltage stability. The CPT series of control transformers gives unparalleled performance stability to our DirectLOGIC line of PLC's and PS series of power supplies. In addition, they are designed to meet the basic needs of industrial applications where electromagnetic devices such as relays, solenoids, and starters are used.

Robustness of design
The CPT series of control transformers uses Mylar, Nomex and other high quality insulating materials. These materials electrically insulate turn-to-turn windings, layer-to-layer windings, primary to secondary windings and ground. The integration of these materials prevents phenomena such as high and low frequency transients and a capacitive coupling effect between the primary and secondary windings. It gives the desirable low temperature rise, providing a wide margin of safety and reliability.

All our CPT transformers are vacuum impregnated with VT polyester resin and oven-cured, which seals the surface and eliminates moisture. Filling the entire unit provides a strong mechanical bond and offers protection from the environment. The robustness can be seen through the UL/CSA/CE approvals.

Information required for proper transformer selection Selecting a control transformer requires that you have a first hand knowledge of the specific application for the transformer, and that you understand some basic terms used
in the selection process. By using the following information, you will be sure to select the correct control transformer for your application.

To select the proper transformer, you must first determine three characteristics of the load circuit. They are:

  1. total steady-state (sealed) VA
  2. total inrush VA
  3. inrush load power factor

Total steady-state "sealed" VA is the total amount of VA that the transformer must supply to the load circuit for an extended length of time. Calculate this by adding the total steady-state VA of all devices in your control circuit. (The operating VA data for the devices should be available from the manufacturer.)

The inrush VA is the amount of VA that the transformer must supply for all components in the control circuit that are energized together. Consideration for the start-up sequence may be required. (Inrush VA data should be obtained from the device manufacturer.)

The inrush load power factor is difficult to determine without detailed vector analysis of all the control components. In the absence of such information, we recommend that a 40% power factor be utilized.

With this information, you can use the 6 sizing steps outlined in the Volume 8 2002 catalog from AutomationDirect.

Common control power transformer questions:

Q. When you calculate the VA requirements of a transformer, do you use the primary or the secondary voltage?
A. When selecting the VA requirement, you use the secondary voltage.

Q. Can you use the control transformer in reverse?
A. Yes, a control transformer can be used in reverse. However, keep in mind the output voltage will be less than its rating, due to the compensation factor of the windings.

Q. Can a control transformer regulate the output voltage?
A. A control transformer will not regulate voltage. Output voltage is a function of the coil's turn ratio only, times the input voltage.

Q. Explain the "VA" or "Volt Ampere Output" rating.
A. The VA or volt ampere output rating designates the output which a transformer can deliver for a specified time at its rated secondary voltage and rated frequency, without exceeding its specified temperature rise.

Q. What is the effect of "Overload"?
A. When a transformer is continually overloaded, excessive heat develops and the insulation system will begin to break down. As a result, the life expectancy of the transformer is shortened due to the heat exceeding the rating of the insulation system.

TECH TALK

Application of the month: Think & Do Live! software and Terminator I/O system offers data logging and remote programming for electroplating systems

Products used: Think & Do Live! software, Terminator I/O

Description: We inherited a product line of laboratory and small production electroplating systems from another division of our parent company. We decided to convert the control architecture from the previous D250 PLC/Exor touchscreen system to a system with Think&Do running on an industrial PC with Ethernet Terminator I/O. By doing so, we were able to offer the following:
· Extensive data logging
· Remote programming by modem
· Improved alarm and fault handling and logging
· Better product recipe capability · A better operator interface

All of this was accomplished for a slightly lower hardware cost and less programming time than the previous control system. The system controls tank heating, variable flow rate pumps, rinse water, and plating rectifiers.
