Product Introduction

The SIRL-5500L is a high-capacity Resistive / Inductive (R/L) Load Bank specifically designed for testing large diesel generators, UPS systems, data centers, power grids, and Battery Energy Storage Systems (BESS).

The complete system is rated at 5500kVA and consists of two independent 2750kVA sections, which can operate separately or simultaneously to provide up to 4400kW resistive load and 3300kVar inductive load at a 0.8 power factor.

With its containerized design, top-airflow cooling structure, and smart local/remote control system, the SIRL-5500L is ideal for factory acceptance testing (FAT), site commissioning, and long-duration reliability verification.
