Resistance Grounded Systems (HRG/LRG)
-
Neutral Grounding Resistors (NGRs) are used to limit the maximum ground-fault current. Restriction of fault current lowers hazards and reduces damage done to equipment. High Resistance Grounding (HRG) systems are often used on industrial and critical power applications to maintain system uptime during a first ground fault. HRG systems are also used in tripping applications to help control touch potential on portable loads and improve personnel safety.

Battery Leak Testers
-
Battery leak testers are crucial tools in the quality assurance process for battery manufacturing. These testers are designed to detect any leaks in battery cells, ensuring that the batteries are safe and reliable for use. Battery leaks can lead to reduced efficiency, potential damage to devices, or safety hazards. By employing sophisticated techniques, such as pressure decay methods or helium detection, battery leak testers can identify even the smallest imperfections in battery casings. These testers are essential in industries where battery reliability is critical, such as in automotive, consumer electronics, and renewable energy sectors, ensuring that the batteries meet stringent safety and quality standards.

Battery Chargers
BAC Series
-
Battery charger BAC series is a portable and universal battery charging solution. It is primarily intended for charging Lead-Acid, Ni-Cd and Li-ion batteries from 1 V DC to 300V DC level. However, the unit can charge the string of any battery type by one of the available charge modes:IU (constant current + constant voltage)UU (constant voltage + constant voltage with a current limit)Charging modes provide a safe regulation of charging procedure and achieves fast recharge and low risk of overcharge.Variety of implemented protections, such as thermal, overcurrent, undervoltage, and overvoltage, assure the charging process will be safe for the battery and the instrument itself.A user doesn’t have to switch off the main charger in order to use BAC series charger. Just the opposite, the BAC series charger should support the main charger to speed up the process. An alternative use is to quickly recharge a battery following a discharge test.The provided display enables users to monitor all relevant information during the charging process and to adjust charging parameters and limits in real-time.The instrument offers the best power-to-weight ratio in the market, weighing only 10 kg / 22 lbs with the maximum output power of 2,7 kW.The maximum charging currents for lead-acid, Ni-Cd and Li-ion batteries, at various battery voltages, are presented in the brochure.
