Advanced Servo Controlled Automatic Power Pack with Proportional Valve for 2/4 Frames


The TC-4850 and TC-4860 Automatic Power Packs with Proportional Valve, are advanced power packs can be used on any testing system ideal for R&D laboratories and Universities for advanced tests with P.I.D. Closed loop control. It can perform tests under load and displacement controls. The frequency of the P.I.D controller and data acquisition is 1000 Hz. TC 4850 and TC-4860 Automatic power packs are designed to supply the required oil to the load frames for loading, unloading or low cycle dynamic testing. All the operations of Data Acquisition and Controls System can be controlled from the touch screen front panel of a 240 x 320 LCD display or computer. The TC-4850 can control up to 2 different frames and TC-4860 up to 4 frames. There is one load cell (or pressure transducer) input and one displacement transducer input for control. There are an extra three analogue channels for other sensors such as load cells, pressure transducers, displacement transducers etc. built in the system. The power pack automatically controls and supplies oil to the frame which is chosen by the user via the touch screen LCD digital control unit or by choosing the test type from the computer software. The type of displacement transducer can be TTL or analogue ( It must be same type for all frames ). The main specifications of the TC-4850 and TC-4860 power packs:

Key Features

  • Pace rate control from 0.01 kN/s to 100kN/s (depends on the specimen stiffness)
  • 3 analogue channels for displacement transducers, extensometers, etc. built in the system as an addition to frame load cells/pressure transducers
  • Instrumentation amplifiers for sensor excitation and amplification
  • 1/65.000 resolution and 1.000 Hz control for each channel
  • Ethernet port for connecting to computer
  • 240 x 320 pixel LCD display
  • Touchscreen operator panel
  • Can control 2 frames (TC-4850) or 4 frames (TC-4860)
  • Can execute load, displacement or strain controlled tests for post peak applications TC-4870 must be selected.
  • Free of charge PC software for test control and advanced report printout
  • Multiple language support
  • Real-time clock/date

Advanced Power Pack can be controlled (Start, Stop commands) by a computer with the software (provided free of charge). This software provides data acquisition and management for compression, flexure and splitting tensile test throughout the test execution for TC-4850 and TC-4860 advanced power packs. The software is capable of running the machine in load control, displacement or strain control.The type of graph or test rate can be changed on the fly. The user can set load or displacement values for making machine to wait till the next command.Engineering functions of elasticity modulus, Poisson’s ratio and energy(for TC-4870 and TC-4880) is automatically calculated. The software can adjust the axes of graphs, supports different type of graphs and calculates 3 different type of elasticity modulus valled tangent, linear and secant moduluses. It also calculates Poisson’s ratio. It can set the gains of the closed loop control, make calibration to the pressure transducer or load cell. It has an easy calibration check facility such as machine keeps load constant at %2, %5, %10 of its maximum capacity for easy check of calibration. Online speed or mode change is available by user-friendly buttons. Various types of graphs respect to used sensors can be monitored during the test. The advanced functions for data base management provide an easy navigation of all saved data. The test results certificate includes all descriptive information. Therefore, test parameters can be set and details about the test carried out such as client details, test type, specimen type, user info and other information required can be entered and printed out as well as test report and graph. The results are exported to Microsoft ExcelTM for advanced research purposes. The data can also be filtered for obtaining intuitive results. The software prepares a summary report.
