For Sale Avo Multi-Amp DDA-1 Digital Data Aquisition Curcuit Breaker Tester CB-8130. This unit is in excellent condition and has been fully tested.
Key Specifications
The DDA-1 system provides precise digital control of the output current and accurate metering for the breaker under test.
- Current Output (CB-8130 Base): Capable of testing up to 30,000 Amperes.
- Digital Signal Processing (DSP): Uses DSP technology to sample output current digitally, ensuring high-accuracy measurements and complete digital control of SCRs.
- Test Capabilities:
- Variable Pulse Time: Allows for specific programmed pulse durations to prevent preheating during testing.
- Variable Firing Angle: Ensures output current is symmetrical by initiating at the zero crossover point, compliant with NEMA AB-4 guidelines.
- Measurement Modes:
- Digital Ammeter: Measures true RMS for pulses >0.5 cycles and peak current for shorter pulses.
- Digital Timer: Automatically starts when current flows and stops when the breaker opens, displaying time in cycles or seconds.
- Digital Voltmeter: Measures input/output voltage and assesses contact condition via voltage drop.
- Compatibility: Designed as a drop-in retrofit for existing Multi-Amp models, specifically:
- Model DDA-30: The specific version for retrofitting the CB-8130.
Physical & Safety Features
- Modular Design: Often used in a three-module configuration (Controller, Power, and Output modules) for portability.
- Safety Interlocks: Includes a ground safety interlock that prevents the output from energizing unless the chassis is properly grounded.
- Construction: Built with rugged enclosures designed to withstand vibration and shock during transportation.
