AC PSU’s

The Thermic Edge AC Temperature Controller Power Supply Range has been designed to be a simple to use, robust, user definable and accurate heater temperature controller combined with an AC power supply, which, together with the optional communications facility, makes this unit a versatile package.

The AC PSU unit is supplied as standard with a mains cable assembly, suitable for local use, to be requested at the time of ordering the unit. A connector kit is provided for the Output, Thermocouple and Interlock Trip Facility. All AC Power Supplies are supplied with RS-232 input as standard. The RS232 feature allows the controller to be connected to the users computer system through Eurotherms free iTools software, which provides data logging capability.

A 24v interlock circuit is also included to enable the power supply to be integrated with interlocks into other systems, or safety interlocks to be attached directly to the unit; which will switch off the enable signal from the unit if the circuit is broken. This enables safety interlocks via make / break switches for things such as chamber lids closed, vacuum interlocks, cooling water flow, over temperature sensors, etc. All AC PSUs come with soft start to protect against transformer current in rush.

Most thermocouple types can be accommodated with automatic cold-junction compensation. The temperature controller will usually be configured for type ‘K’; other types are available as an option upon request. The unit is compliant with relevant EU directives.

DC PSU’s

Thermic Edge’s new SMP range of Switch Mode DC Power Supplies offer a lightweight, cost effective alternative to AC Power Supplies. DC power supplies, due to their stable current, offer an intuitive, easy to use system for a variety of systems requiring power. The power supplies don’t require a transformer, so are far lighter than AC PSUs while also providing a much smaller footprint in the workplace. The Thermic Edge DC Power Supplies are an excellent solution for powering and controlling any system requiring stable, accurate, and safe power delivery

All DC PSUs are fully compatible with our range of heater controllers. The controller is housed in a separate 3U unit. The Thermic Edge Heater Temperature Controller has been designed to be a simple to use, robust, user definable and accurate heater temperature controller that, together with the optional communications facility, makes this unit a very powerful package. The controller unit is 3U high, half rack width, and is compliant with relevant EU directives.

A 24v interlock circuit is also included to enable the power supply to be integrated with interlocks into other systems, or safety interlocks to be attached directly to the unit; which will switch off the enable signal from the unit if the circuit is broken. This enables safety interlocks via make / break switches for things such as chamber lids closed, vacuum interlocks, cooling water flow, over temperature sensors, etc.

Heater Controllers

The Thermic Edge Heater Temperature Controller has been designed to be a simple to use, robust, user definable and accurate heater temperature controller that, together with the optional communications facility, makes this unit a very powerful package. The unit is 3U high, half rack width, and is compliant with relevant EU directives. The unit operates by outputting a 0-10v control signal controlling either a Thyristor, SSR or PSU.

All controllers are supplied with RS-232 input as standard, as well as extensive safety features to ensure low-risk operation. This package also includes software, making external control extremely powerful and simple to use. A 24V interlock is also provided to cut the enable signal should the circuit be broken, example, to maintain the overall system pressure within limits.

The unit is supplied as standard with a mains cable assembly, suitable for local use, requested at the time of ordering the unit. A connector kit is provided for the Output, Thermocouple and Interlock trip facility. The unit must also be earthed via the rear panel stud provided; use 2.5mm2 cable or braid connected to your system ‘star-point’ earth.

The unit contains a PID controller (Proportional with Integral and Derivative). This provides an auto-tuning function to dynamically tailor the power supply output to the requirements of the heater to reach the desired temperature in an accurate safe, and efficient manner. Thus, overshooting is avoided during temperature ramping. This function is fully compatible with any power supply using a 0-10V input signal.

The Thermic Edge Heater Temperature Controller has been designed to be a simple to use, robust, user definable and accurate heater temperature controller that, together with the optional communications facility, makes this unit a very powerful package. The unit is 3U high, half rack width, and is compliant with relevant EU directives. The unit operates by giving a 0-10v output signal controlling either a Thyristor, SSR or PSU.

• As standard our heater controllers are fitted with Eurotherm PID temperature controllers, to very accurately control heater ramping and set points without over shooting or deviation.
• Alternative PID controllers such as RKC or West can also be used if preferred by our customer.
• Enable switch located on the front of the unit.
• LED Status display on front of unit detailing supply, interlock and output status.
• Data logging capability with Eurotherms free iTools software.
• An auto tuning facility enables the controller to accurately tune to the heater to its environment, and therefore avoid overshooting during temperature ramping.
• Remote control is available via Modbus RS232 or RS485
• All controllers have a 24v interlock circuit, which will cut the enable signal if the circuit is broken. This can be used to interlock many safety features such as lid closed, water flow, high vacuum enabled, over temperature etc.
• Pressure hold facility is available that links to a pressure sensor and will cut the controller enable signal, switching off the psu, if the outgassing due to heating raises the chamber pressure above the set point pressure.

Temperature controllers are utilised to monitor and control a thermal system such as a substrate heater, stage, or furnace. The controller operates by comparing the temperature measured via a suitable input, usually a thermocouple, and the setpoint on the controller. In this way, the controller can then switch on or off the power supply to the heater to either increase or decrease the temperature of the system.

It is important that a suitable temperature sensor is used alongside the controller. Different sensors have different operating temperatures. Thermocouple types should be specified alongside the controller in order to ensure accurate and stable operation. Most thermocouple types can be accommodated with automatic cold-junction compensation. The controller will usually be configured for type ‘K’; other types are available as an option. The thermocouple type and range is software selected, all that needs to be added is the correct type compensation cable and connectors.

The unit contains a PID controller (Proportional with Integral and Derivative). This provides an auto-tuning function to dynamically tailor the power supply output to the requirements of the heater to reach the desired temperature in an accurate safe, and efficient manner. Thus, overshooting is avoided during temperature ramping. This function is fully compatible with any power supply using a 0-10V input signal.

PID tuning is a method by with the controller increases the accuracy and stability of the system through a trial and error process. This process means that PID controllers are the most stable and accurate system of control compared to On/Off and Proportional Temperature controllers.

In normal operation the temperature controller will display actual and target temperatures (whether or not set point ramp-rate or self-tune is invoked) or indicate if the temperature sensor has failed. In the full configuration mode, all parameters and values can be viewed and edited. Control can be PID, PI, PD, P only or ON/OFF, with values automatically set or manually entered. The output power level is programmable if the sensor fails.

For processes where the maximum temperature must not be exceeded, the ramp-rate facility allows the user to define the temperature rise in programmed units (per second, minute or hour). A self-tuning algorithm automatically sets the PID and the under and overshoot values.

All controllers are supplied with RS-232 input as standard, as well as extensive safety features to ensure low-risk operation. This package also includes software, making external control extremely powerful and simple to use. A 24V interlock is also provided to cut the enable signal should the circuit be broken, example, to maintain the overall system pressure within limits.
