DDA-16, DDA-30and DDA-60
Digital Data Acquisition Instrumentation and Control System

◆　　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

The DDA-16, -30, -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.
