Detailed Product Description

Description:

Libratherm offers ready touse two zone and four zone temperature control panel for heater control inplastic injection moulding machines. The control panel comprisesmicrocontroller based PID temperature controller, Auto/Manual selectorswitches, manual potentiometers and current meters on the front. Back side ofthe panel has provision for easy connection of sensors, heaters and power cable.Maximum Heaters of 4KW @ 230VAC can be connected per zone and the heater poweris controlled through suitably rated Solid state relays, using PID controllersin the Auto mode and using potentiometer in the Manual mode. The Auto/Manualselection is through the toggle switch on the front panel.

The heart of the panel isLibratherm make PID controller model PID-723, which accepts J, K or Pt-100 sensors as the input andprovides PID control output in the form of DC pulses to control outputs tocontrol the SSRs. The front panel current meter shows the heater status and thecurrent flowing through each heater. The manual control operation is performedby using special PWM card accepting input from thepotentiometer. Each heater is protected against short circuit using the individual MCB switches.Heaters are connected using standard 16A plug/sockets for easy connections anddisconnections. AC supply to the panel is also connected through heavy duty plug and socket. Cooling fan isprovided to exhaust the heat generated inside the panel.

The panel can be mounted onthe bench close to the injection moulding machine, it is user friendly to operate and easy to maintain.
