ESPEC's new P-300 programmer/controller with USB

New P-300 controller with USB

Get improved performance, energy savings, plus USB or Ethernet access

The exclusive ESPEC P-300 controller now has USB and Ethernet features to make programming and data collection easier than before. The updated user interface uses tabs for faster access to any screen. Standard USB and optional Ethernet interfaces make programming and data acquisition much simpler. In addition, improved algorithms make operation faster and smoother.

Built on the success of ESPEC's SCP-220 programmer, existing users will find the user interface familiar, yet streamlined. RS-232 and GP-IB protocols have not changed, so existing custom software and LabView apps can be used. The system is still built on a dedicated PLC controller for robustness and long-term reliability.

New USB port for upload/download of test profiles and test data

  • Test programs can uploaded or downloaded from the P-300 via USB thumb drive.
  • Create, edit, and store programs on a PC using the included Pattern Manager Lite software.
  • Accurate, repeatable testing by uploading the same program to multiple chambers.
  • Create your own back-up archive of programs, and get additional profiles from ESPEC's library.
  • Retrieve and download test operation data via USB thumb drive. Data timeframe is selectable.
  • For integrity, viewing test data on a PC and exporting to Excel requires included Pattern Manager Lite software.

Energy-saving operation

Invisible to the end user, the P-300 uses advanced cooling control via an electronic expansion valve, saving energy and improving temperature stability. Sophisticated future-looking algorithms make temperature ramping faster and smoother. These high-end features are unique to ESPEC. Additional improvements in refrigeration and heater operation will make the next generation of ESPEC chambers the most energy efficient ever.

Additional capabilities

  • Store up to forty programs, as well as three different constant-mode set-ups.
  • Multilingual display in English, Japanese, Chinese, or Korean.
  • Alarm diagnostics and history, plus a ‘back trace’ feature for troubleshooting.
  • Three programmable timers allow the user to set reminders for maintenance or other actions.
  • Energy saving by using only one compressor when testing above -10°C (for cascade refrigeration models).
  • Optional Ethernet/browser-based Web Controller access can also be used to upload and download programs, as well as data.
  • Optional Product Temperature Control allows faster ramping to the desired conditions on the sample.
  • Computer interface options for specialized programs: RS-232/serial or GP-IB with LabView drivers.
