Description

Features

RADIX brings you a full range of Thyristor (SCR) Power Regulators, which are compact in size, robust in design and easy to maintain.

These Power Regulators control power to the resistive or inductive heating loads which can be single-phase, two-phase or three-phase. They

can switch load power extremely fast providing the means to respond rapidly to command changes, load changes and power supply changes.

This feature allows the control of fast responding loads and eliminates the negative effects of variations in load or supply voltages that can occur

with other types of control.

Radix power regulators comprise of triggering card, suitably rated back-to-back connected SCR modules mounted on special aluminium-alloy

heat sink duly isolated electrically .

The cooling is either natural cooling or forced air cooling using high speed noiseless air circulating fan(s).

Input and output terminals are clip-on type heavy duty connectors or copper bus bars.

For safety, suitably rated semiconductor fuses and thermal cut-out is provided.

The entire assembly is mounted on the very sleek and easy to install Anodized Aluminium enclosure with safety ABS removable covers.

Operates on phase angle zero cross over technology

15 Amps to 750 Amps current carrying capacity

Single phase / 2 phase / 3 phase versions.

Suitable for 3 star without neutral / closed delta configuration.

Auto / Manual operation.

Accepts (4-20)mA / (0-5)VDC / (0-10)VDC control input.

Soft start for smooth control.

Adjustable power and current limit.

Isolated heat sink for safety.

Simple and Modular design for easy servicing of cards and Thyristors.

Ideally suitable for resistive, transformer, inductive or heating loads like Silicone Carbide and Molybdenum which exhibits significant

changes of resistance with increase in temperature.

Cooling fan have temperature control which extends it life.

It has a Relay output for remote supervision under following conditions : Phase failure, Fuse blown and Heat sink Over temperature

Ideal replacement for traditional mechanical contactor / relay accepting DC logic input signal

Advantages

SCR power controllers provide a relatively economical means of power control. SCR power controllers cost less and are more efficient than

saturable core reactors and variable transformers. Compared to contactors, SCR power controllers offer a much finer degree of control and do

not suffer from the maintenance problems of mechanical devices. Features and benefits of SCR power controllers over other forms of control

include:

High reliability

Because the SCR power controller is a solid-state device, there are no inherent wear-out modes. Thus, they provide virtually limitless and

trouble free operation.

Infinite resolution

Power, current or voltage can be controlled from zero to 100% with infinite resolution. This capability allows extremely accurate, step less

control of the process.

Selectable control parameters

The SCR power controller can provide useful features such as current and voltage limiting. The ability to control the desired parameter as a

function of a command signal and to incorporate limiting features is not normally available with other types of control.

Minimum maintenance

Because they are solid state there are no moving parts to wear out or replace. Therefore, the routine replacement required in some forms of

control is eliminated.

Radix Thyristor Power regulators has a varied application and can be used with heating elements like Nichrome, Kanthal - A1, Super Kanthal,

Silicon Carbide/Molybdenum Di-Siliside, Infra Red, etc where precise and accurate temperature control is desired. It can also be used in DC

rectification application.

Few of the industrial application where Radix power regulators are used

1. Heat treatment 9. Extruders

2. Automobile industry 10. Plastic Industries

3. Stress Reliving 11. Environmental Chambers

4. Jewellery industry 12. Upsetting machines for Engine Valves manufacturing

5. Wax burn out 13. Electro magnetic Cranes

6. DC rectifiers 14. Multi zone heating system

7. Low voltage - High Current heating system using Transformers 15. Electrolysis

8. Injection moulding machines 16. Research Laboratories, Atomic power stations and many more

applications

Ready-to-use SCR-based

Control Panels from Radix

RADIX offers Ready to use Control Panel for electrical

furnaces, ovens or any other electrical heating system,

which can be used by the OEMs or the end users. The

panels are fabricated using CRC MS sheet duly powder

coated / EPOXY coated (usually Siemens Grey colour -

other colour shades are also available on request) or in

Stainless steel .

These panels comes fitted with accessories depending on

the application like highly accurate & versatile controller,

safety controller, PLC, HMI. Current meters, Energy

regulator, MCB / MCCBs, safety contactors, etc.

The front facia of the panel incorporates switch gear

components, meter, etc for easy access and user friendly

for safe operation of the panel.

The incoming power line MCBS or MCCBS of suitable

ratings are used for switching the electrical supply to the

panel. Suitably rated fuses are incorporated per phase or

per heating arm. Digital or Analog current meters are

installed on the panel to monitor the current flowing through

the load.
