Substrate Heater Controllers and Substrate Heater Power Supply

Our range of heater controllers and power supplies offer the complete solution to powering and controlling every possible kind of heating element. All our controllers are fitted with a Eurotherm 2216e PID temperature controller which enables the heater to be held at exactly the set temperature. A tuning facility enables the controller to accurately tune to the heaters requirements and therefore avoid overshooting during temperature ramping. The control enables ramping and cooling between two set points at a specified ramp rate. The heater controller can also be controlled remotely and integrated in system computer control programs via modbus RS232, RS485 and other protocols.

All our heater controllers have power on / off switch to the whole unit, and an output enable switch to isolate the output from the controller. 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 output 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.

Our standard units are 50v or 115v burst-fire output (240v x 13 amp 50hz input). The 1kw unit is available in 3U x full 19" wide rack mount, or 3U half rack mount, both with integrated transformer. Our 1.5kw unit is available in 3U half rack mount only.

Above 1.5kw a separate transformer box is required.

Graphite Substrate Heater Controller and Substrate Heater Power Supply

Graphite elements require a special kind of temperature controller to accurately control them across the complete temperature range. Graphite has a lot of electrical peculiarities that occur at various points across the complete temperature range from ambient to 2000C+. Standard controllers and power supplies that use burst fire thyristors are not really suitable. Ceramisis has developed a heater controller specifically for graphite elements. The controller is 3U half rack mount or bench top mount, with a separate transformer box. Our heater controller and power supply offers the complete solution to powering and controlling graphite heating elements. Fitted with a Eurotherm 2216e PID temperature controller which enables the heater to be held at exactly the set temperature. A tuning facility enables the controller to accurately tune to the heaters environment and therefore avoid overshooting during temperature ramping. The control enables ramping and cooling between two set points at a specified ramp rate. The heater controller can also be controlled remotely and integrated in system computer control programs via modbus RS232, RS485 and other protocols.

Our graphite substrate heater controllers have power on / off switch to the whole unit, and an output enable switch to isolate the output from the controller. 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 output 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.

The graphite substrate heater controllers run on 240v 50hz supply as standard, current requirements vary depending on the size of element and the element temperature. Other voltage inputs can also be catered for on request.

 

"Power Block" - 3KW Substrate Heater Power Supply
The Ceramisis "Power Block" substrate heater power supply is a very basic power supply that is controlled by a front panel mounted potentiometer, which controls the output from 0 to 100% via a phase angle control thyristor. There is no heater controller, this is purely a manual power supply that will supply a set power from 0 to 100%. The actual maximum voltage and current output can be specified by our customer depending on their individual requirements. The 3KW power block shown here is for a graphite element and has a maximum output of 30 volts x 100 amps. It is possible to set an internal current limit, so that it is not possible to overload the element being powered, even if the pot is set to 100%.

The power block also has our 24 volt safety interlock circuit, the same as our temperature controllers. This enables safety interlocks to be set up via make - break sensors or switches, which will cut the power output from the power block if the safety interlock circuit is broken. This can be used to interlock enclosure doors, over temperature safety, cooling water flow, vacuum level etc.
