Product catalog summary
Overview: The document provides detailed specifications and features of the C.A 771 and C.A 773 Voltage Absence Testers (VATs), designed for low-voltage applications both indoors and outdoors. These devices are suitable for extreme conditions and comply with various international standards.
Specifications: The VATs are rated for CAT IV 1,000 V and can handle voltages up to 1,000 Vac and 1,400 Vdc at frequencies up to 800 Hz. They feature IP65 protection, making them resistant to dust and water, suitable for harsh environments.
Key Features:
  • Autotest Functionality: Integrated autotest with fault type indication. The C.A 773 provides additional text messages for comprehensive information.
  • Continuity and Resistance Testing: Audible and visual indicators for continuity up to 100 Ω. Extended continuity tests available with thresholds at 2 kΩ, 60 kΩ, and 300 kΩ.
  • Phase Detection: Two-pole phase-sequence testing using the "2-wire method" up to 400 Hz, suitable for isolating transformers and generator sets.
  • RCD Trip Testing: Capable of testing residual current devices up to 30 mA.
  • Voltage Detection: Automatic detection with visual (bargraph) and audible signals. Stray voltage detection via low-impedance mode.
Ergonomics and Design: The devices are designed for field use with features like a digital display (C.A 773), molded test probes for better handling, and built-in LED lighting for measurement points. Removable test probes are available for compliance with specific regulations.
Standards and Safety: The VATs comply with IEC 61243-3:2009, EN 61243-3:2010, and IEC 61010 standards, ensuring high safety and performance levels. They include redundant safety features like an Extra-Low Voltage (ELV) LED that indicates hazardous voltage levels.
Applications: Suitable for various environments, including installations at altitude, underground, refrigeration, greenhouses, and service vehicles. The extended climatic class allows operation in temperatures from -22°F to +140°F.
Ordering Information: The document provides contact details for AEMC, the manufacturer, and includes ordering references for the C.A 771 and C.A 773 models.

CAT IV 1,000 V Voltage Absence Testers (VATs) STANDARDS Voltage Absence Testing: a clearly-defined procedure In the context of work on installations connected to the electricity distribution network, the standards stipulate that the measurements must be performed with the power off to avoid electrical hazards (EN 50110-1 standard, DIN VDE 0682-401, NF C 18-510, etc.). To secure the installation and ensure that it is non-current-carrying, there is a procedure called Separation which imposes the use of a Voltage Absence Tester.

APPLICATIONS Voltage up to 1,000 Vac / 1,400 Vdc at up to 800 Hz The specifications of the C.A 771 and C.A 773 mean they can be used for work on all LV electrical networks, whether they are electricity distribution networks or the more specific networks encountered in naval or aviation applications. Climatic conditions The type-S extended climatic class allows use in extreme temperature conditions. This means it offers an operating range from -22°F to +140°F for applications such as: • Installations at altitude (mountains, etc.), underground installations, etc. • Refrigeration installations,...
