The DDA-16, DDA-30, DDA-60 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 allow a user of Multi-Amp 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 SCRs and digitally samples the output current for high-accuracy measurements.

Features:

Drop-in retrofit capability to the Multi-Amp Model CB-9116, Model DB-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
