Simplex

Simplex is a manufacturer of portable AC load banks engineered for commissioning, testing, and validating power generation and distribution equipment. Their load bank product lines — including the INFINITY and SWIFT-E series — are designed to provide controllable resistive loads for testing generators, uninterruptible power supplies, and related power infrastructure under realistic operating conditions. Portable load banks are essential tools for verifying that power equipment meets its rated output capacity, performs stably under load, and responds correctly to transient conditions before critical systems are placed into service.

The SWIFT-E PLUS and SWIFT-E ULTRA portable AC load banks are designed for field deployment, offering compact form factors with robust load step control. The INFINITY-200 series provides higher-capacity testing suitable for larger generator sets and data center power systems. These units enable scheduled maintenance testing, acceptance testing, and generator load bank testing in accordance with NFPA 110 and other relevant standards.
