As the global shift toward electrification accelerates—with lithium-ion batteries powering electric vehicles, energy storage systems, and consumer electronics—safety and reliability have become non-negotiable standards for manufacturers. A critical step in ensuring product integrity is withstand voltage (hi-pot) testing, which verifies insulation performance and detects potential breakdown risks. Addressing this critical need, AOT-RK2674 Series Battery Hi-Pot Tester, a versatile, high-precision instrument designed to deliver accurate insulation breakdown and destructive testing across industries. From battery components to household appliances and high-voltage cables, this series sets a new benchmark for electrical safety testing, combining durability, usability, and adaptability for modern manufacturing workflows.
A Versatile Series for Diverse Testing Needs
The RK2674 series stands out for its comprehensive product lineup, catering to a wide range of voltage requirements and application scenarios. Available in five models—RK2674-15, RK2674-AC20, RK2674A, RK2674B, and RK2674C—the testers cover AC/DC voltage outputs from 0–15KV to 0–50KV, with testing current ranges of 0–2mA up to 0–40mA. This flexibility makes the series suitable for everything from small electronic components (e.g., diodes, connectors) to large-scale high-voltage equipment (e.g., EV battery packs, industrial cables).
Notably, the series supports both alternating current (AC) and direct current (DC) testing modes, except for the RK2674-AC20 model which focuses on AC applications. This dual-mode capability allows manufacturers to comply with diverse international safety standards (e.g., IEC, UL, GB) and tailor tests to specific product requirements. For instance, DC testing is ideal for evaluating insulation in battery cells and modules, while AC testing is preferred for household appliances and power tools.
Core Performance: Precision, Durability, and User-Centric Design
The RK2674 series is engineered to deliver reliable results in demanding production environments, with performance features that address key pain points for quality control teams:
1. High Accuracy and Real-Time Monitoring
Equipped with high-brightness LED digital displays, the testers provide clear, real-time readouts of test voltage, leakage current, and duration—critical for identifying insulation weaknesses. With a test precision of ±5%, the series ensures consistent, repeatable results, minimizing false positives and negatives. The RK2674B and RK2674C models, capable of outputting up to 50KV, are particularly suited for destructive testing of high-voltage insulation materials, such as those used in EV battery casings and power cables, where detecting breakdown thresholds is essential.
2. Flexible Testing and Alarm Customization
Manufacturers can tailor test parameters to their needs: test time is adjustable from 0.0 seconds (continuous testing) to 999 seconds, while alarm current values can be preset continuously. This flexibility allows for both quick spot checks on production lines and long-duration stability tests in R&D labs. When a test object fails (e.g., insulation breakdown occurs), the tester triggers an immediate alarm, stopping the process to prevent defective products from advancing to downstream stages.
3. Industrial Compatibility and Safety Features
The series prioritizes integration with modern manufacturing workflows: optional PLC signal input/output interfaces enable seamless connection to automated production lines, forming comprehensive testing systems that reduce manual intervention. Safety is also a top priority, with built-in high-voltage warnings, grounding protection, and durable voltage regulator technology that ensures reliable operation even in high-stress environments. The testers’ robust construction—ranging from desktop models (33.4KG) to cabinet-type designs (68.84KG)—accommodates both lab and factory floor use.
Wide-Ranging Applications: From Batteries to Industrial Equipment
The RK2674 series’ versatility makes it a cornerstone tool across seven key sectors, underscoring its relevance beyond battery manufacturing:
Battery and Electronic Components: Tests insulation performance of lithium-ion battery cells, modules, diodes, transistors, and high-voltage silicon stacks—critical for preventing short circuits and thermal runaway in EVs and energy storage systems.
Household Appliances: Ensures safety in TVs, refrigerators, air conditioners, and chargers by verifying insulation between live parts and casings.
Insulation Materials: Evaluates heat shrink tubing, capacitor films, PCB circuit boards, and protective gear (e.g., insulation gloves) to meet industry safety standards.
Instruments and Meters: Validates the insulation of oscilloscopes, DC power supplies, and switching power supplies, ensuring accurate performance in professional settings.
Lighting and Electric Heating Appliances: Tests ballasts, road lights, electric drills, and welding machines, reducing fire risks caused by insulation failure.
Wire and Cable: Conducts high-voltage tests on power lines, silicone rubber cables, and industrial cables, ensuring reliability in power transmission.
Industry Impact: Advancing Safety in the Electrification Era
As the demand for high-performance, safe batteries and electronics surges, the RK2674 series plays a pivotal role in upholding quality standards. For battery manufacturers, in particular, the tester’s ability to detect insulation defects early in production reduces recall risks and ensures compliance with strict safety regulations (e.g., UN 38.3 for battery transportation). In EV manufacturing, where a single insulation failure can lead to catastrophic consequences, the RK2674 series provides an added layer of protection, boosting consumer confidence in electrified transportation.
The AOT-RK2674 Series Battery Hi-Pot Tester is more than a testing instrument—it is a critical enabler of safety and reliability in the electrified world. Its versatile voltage ranges, high precision, and user-friendly design make it indispensable for manufacturers across industries, while AOT’s decades of expertise and global support ensure seamless integration into production workflows. As the world continues to embrace clean energy and smart technologies, the RK2674 series stands as a testament to how precision testing can accelerate innovation while prioritizing safety—ultimately building a more reliable and sustainable future for all.
