The MAC-21 uses proven microprocessor and A/D converter technology to provide real-time waveform analysis. This ensures accurate true-RMS readings of current pulses, even with DC offset and distortion, which are typical in primary injection testing. Intelligent threshold algorithms provide accurate trip time measurement. Integration of measurement and control functions allow advanced features such as preset on times, auto ranging, and optional printer or computer interface.
Front panel controls consist of large rugged pushbuttons with tactile feedback and LED indicators. Time and current are displayed on large, bright LED displays.
Standard components and modular construction are used for high reliability, simple service, and low cost. The Package is a rugged, standard 19″ x 7″ rack mounting assembly that easily mounts in most high current test sets. All inputs and outputs are provided through a standard twist-lock connector, which is compatible with the EIL Accu-Amp, and allows easy removal of the instrumentation package for service or safe transportation.
The MAC-21 Monitor Ammeter Controller is recommended for replacement of older current meters, timers, and control panels in circuit breaker test sets of such manufactures as Multi-Amp/Megger, EIL Instruments, Phenix, Hipotronics and other circuit breaker testers.
UPGRADE TEST SET
The MAC-21 digital ammeter / timer and control upgrade module can be used with many older circuit breaker testers such as the Multi-Amp Model CB-8115, CB-8130 or CB-8160 circuit breaker test set.
