PROFESSIONAL rlc load bank MANUFACTURER

Product Overview 

Resistive-Reactive(Inductive)-Capacitive Load Bank is a professional three-in-one composite dummy load testing device that integrates resistive, inductive and capacitive loads independently. Also known as RLC load bank, 3-phase adjustable power factor load bank, anti-islanding test load bank and reactive power simulation load bank, it covers pure resistive, pure inductive, pure capacitive, RL, RC, LC and full RLC composite load modes. It supports continuous adjustable power factor (0–1 leading and lagging), which can fully simulate complex industrial power grid operating conditions including motor inductive load, capacitor compensation load and daily comprehensive power consumption load. It is the standard professional equipment for new energy anti-islanding testing, power factor calibration, generator transient performance testing, UPS and inverter full-parameter verification.

LINGDING RLC 3-in-1 load bank series includes portable mobile type and container fixed type, with full power coverage of 10kW–50MW. It adapts to global 50/60Hz frequency and multi-country voltage standards, with three sets of loads independently controlled and freely combined. Equipped with high-precision data acquisition system, intelligent PLC control and full safety protection, it has passed CE and ISO9001 certification. Widely applicable in new energy power generation, power grid engineering, laboratory testing, power station acceptance and high-end power equipment manufacturing.
