Understanding SCR Power Controls

When selecting SCR Power Controls, it is important to have a basic understanding of how SCRs work. This will help you select the right SCR for your application.

• How SCR Power Controls Work

A silicon controlled rectifier (SCR) is a solid state switching device which can provide fast, infinitely variable proportional control of electric power. Not only does this give maximum control of your heat process, but it can extend heater life many times over other control methods. Since the SCR is solid state, it can cycle on and off over a billion times, if properly used.

• PHASE ANGLE FIRED

controls proportionally turn on a percentage of each power line half cycle. This gives smooth, infinitely variable application of power to the heaters. Imagine a light dimmer and how it provides power to a light bulb. This method will provide the most precise control of heaters. Phase angle fired SCR's will respond the fastest to load changes and provide maximum heater life. Options including Voltage Limit, Soft Start and Current Limit are only available with Phase Angle Fired SCR's.

• ZERO VOLTAGE SWITCHED ( ZERO VOLTAGE CROSSING)

controls proportionally turn on and off each full cycle of the power line cycle. By varying the number of AC power line cycles, the SCR provides power to the heaters. With a variable time base, the optimum number of cycles turned on/off is achieved. The switching is done at fractions of a second during the zero voltage crossing of the power line cycles. For IR heating with a fast element, you would see the elements flickering. On a ceramic heater, or more massive medium wave heater you can control within very tight tolerances.

• ON/OFF CONTROL

works like a mechanical or mercury relay. When the SCR is turned on it fires full voltage into the heater until the command signal turns it off.

• The advantages of SCR Controls over other temperature control methods

- Improved response time

- Closer process control

- Extended heater life

- Reduced maintenance costs

- Silent operation

- Reduced peak power consumption

Remember, a heating element is made of wire in most cases. If you use a mechanical relay to turn on your heater, it will cycle on or off within 30 seconds or longer. The heater will expand and contract, getting more and more brittle each time. This is called thermal shock. Temperature overshoot may also occur. Relays also arc, spark and will burn out on a regular basis.

POWER CONTROL SELECTION GUIDE

The SCR power control can deliver electrical power to heaters in several ways: phase angle

fired, zero voltage switched and on/off control.

Phase angle fired controls proportionally turn on a percentage of each power line half cycle. This gives smooth, infinitely variable application of power to the heaters. It is the most precise method of control. Phase angle firing can increase heater life

up to seven times depending on

heater type.

Phase angle firing also allows options such as soft start, voltage limit and current

limit. These options are not available with any other means of control.

Zero voltage switching controls proportionally turn on and off each full cycle of the power line. By varying the number of AC power line cycles, the SCR provides power to the heaters. With a variable time base, the optimum number of cycles turned on/off is achieved. This method produces less RFI line noise than phase angle fired SCRs.

On/Off controls function the same way as a mechanical or mercury relay, but with the advantage of much faster cycle times.

Chart below shows how to best match SCR power control with typical applications.

APC-TF Series MAINTENANCE Thyristor protection

Thyristor protection

The thyristors in the APC-TF series controllers are protected in the following way:

· external high speed fuses against over-currents (except for short-wave infrared applications)

· RC snubbers and MOVs (varistors) protect against over-fast voltage variations and transient

over-voltages when the thyristors are not conducting.

*** MOVs (varistors) install : Optional

APC-TF Series SERVICING

APC-TF Series controllers must be mounted with the heatsink positioned vertically, with no obstructions above or below which could inhibit or impede airflow.

Attention!

If several units are mounted in the same cabinet, they should be arranged in such a way that air expelled from one

cannot be drawn into the unit located above it.

In order to ensure correct cooling of the unit, users are advised, depending on the degree of environmental pollution, to regularly clean the heatsink and (for 90A rating units) the protective fan guard.

DANGER!

Cleaning should only be carried out when the controller supply is disconnected and at least 15 minutes after it has ceased operating.

Every

six months check that the screws of the power and safety earth cables are

correctly tightened.
