DX5300 Rack multichannel TEC controller
DX5300 Rack multichannel TEC controller allows simultaneous driving and characterization of up to 24 independent TECs or TEC assemblies. It is an ideal instrument for control of thermoelectric coolers and assemblies during reliability and lifetime studies.
DX5300 key features
- Simultaneous testing of up to 24 TECs
- 32 W per channel
- TEC parameters monitoring during testing
- Self-switching-off reaching preset end-of-test criteria
- Tests according Telcordia, MIL-STD-883 and others
- TEC testbed control block for accelerated testing
- Custom test programs
- Custom testbeds for TECs and assemblies
DX5300 combines all features of our TEC controllers and Z-meters including a number of various TEC operation modes and precise measurements and characterization of changes of TEC parameters during operation. TEC operation modes possible are PID, constant voltage, relay. TEC parameters controlled are TEC current and voltage, temperature, AC resistance R, figure of merit Z, time constant Τ. Additional optional TEC testbed control unit allows heating and temperature control of testbed with TECs and is very useful in case of accelerated TEC testing.
The software allowing various test programs including cycling test according to requirements of Telcordia GR468 Core and MIL-STD-883 F is supplied together with the system. The software analyses TEC performance in time and automatically highlights particular channel where changes require special attention. Every particular channel will self-switch-off if any TEC parameter will reach its preset end-of-test limit. The software may be also used for generation of test reports.
The rack consists of Power Supply unit for supply of temperature controllers and other internal electronics, TEC Control Unit and (optional) TEC Testbed Control unit. Interfaces available are RS 485, and USB.
PL Engineering Ltd. also offers development of custom testbeds for testing of particular coolers and assemblies and custom software to fulfil various specific test requirements.
