Drive/power electronics for LM-80 testing form the foundation for successful testing. Selecting the best drive electronics is a very important decision.
Selection criteria for your LM-80 drive/power electronics should include the following:
LM-80-08 Testing Requirements
- Constant Current (DC mode) (yes, with SpikeSafe current source; user selectable currents)
- Pulse mode current (allowed LM-08-15) (yes with SpikeSafe current source; user selectable currents and pulse settings)
- Current accuracy less than 3% (yes. SpikeSafe current source accuracy is less than 1%)
- Temperature measurement monitoring and data logging (thermocouple – special limits wire) (yes)
- Alternate temperature measurement monitoring techniques – RTD or thermistor (yes)
- Minimum 6,000 hours test time (10,000 recommended) (SpikeSafe MTBF 10,000 hours)
- Duration timers set by operators stop testing and alert users that it is time for light measurements
- Test Timing Uncertainty for the software application must be calculated to ensure minimum testing is achieved (yes)
- RH less than 65%
- AC ripple less than 2% (yes, with SpikeSafe current source)
- NVLAP Self Certification
- LM-80 audit (Vektrex systems have been successfully audited and are in use in many countries)
Other criteria for selection of your LM-80 drive / power electronics
- Is the system constructed from high quality components?
- What is the uptime and MTBF?
- What is the Energy Efficiency?
- Does the system include safety mechanisms for operators and devices?
- What is the worldwide installation base?
- Does the system meet the LM-80 Specifications?
- Is the system NVLAP auditable?
- Does the software support the test requirements?
- Does the software include management functions that simplify test management?
- Are you able to easily detect test anomalies?
- Is the system scaleable and modular?
- Does the system support a large voltage and current range ?
