DDA-16,
DDA-30 and DDA-60
Digital Data Acquisition Instrumentation and Control System
- DDA-16, DDA-30 and DDA-60.
- Drop-in retrofit capability to
models CB-9116, CB-8130 and CB-8160 test sets.
- Variable pulse time and
firing-angle output-current control.
- Complies with NEMA AB-4 test
guidelines.
The DDA-16, -30, -60 use DSP
(digital signal processing) technology to control the circuit
breaker test sets and measure the reactions of the breaker
under test. The retrofit capabilities allow a user of circuit
breaker tests sets the capability of upgrading existing
systems without the expense of purchasing a new system. The
DSP technology provides complete digital control of the SCR's
and digitally samples the output current for high-accuracy
measurements.
