DIGITAL DATA ACQUISITION INSTRUMENTATION AND CONTROL SYSTEM
- Drop-in retrofit capability to the multi-amp model CB-9116, model CB-8130, and model CB-8160 circuit breaker test sets
- Digital Signal Processing (DSP) technology
- Variable pulse time and firing-angle output-current control
- Complies with NEMA AB-4 test guidelines
The DDA-16, DDA-30, and DDA-60 are digital data acquisition instrumentation and control systems designed for the high current circuit breaker test systems. The system is designed not only to be installed into new Megger high current circuit breaker test sets but also to be reverse compatible. Each unit in the series can be easily installed into existing multi-amp model CB-9116, model CB-8130, and model CB-8160 circuit breaker test sets:
- Model DDA-16 (as retrofit to Model CB-9116)
- Model DDA-30 (as retrofit to Model CB-8130)
- Model DDA-60 (as retrofit to Model CB8160)
The DDA series use the latest in DSP technology to control the circuit breaker test sets and also measure the reactions of the breaker under test. The retrofit capabilities give the user of multi-amp circuit breaker tests sets the ability to upgrade their existing systems without the expense of purchasing a new system. The DSP technology provides complete digital control of the SCRs and digitally samples the output current for high accuracy measurements.
