LS Series Description

LS series load banks are designed for permanent installation suitable for harsh outdoor environments. Featuring the Smartload LSM800D processor, providing accurate load control with incremental load steps to maintain generators at a constant set load, eliminating wet stacking and cylinder bore glazing.

The control software is designed to load and maintain one or more generators, typically a single generator operation or when in parallel. The LSM800D provides user-friendly field settings, digital display and is available with options to include a remote manual override “Mimic” control panel with Auto Exercising function and Modbus interface. For regenerative applications, units are available with the LSM800DRG regenerative control system.

Sephco load banks incorporate immersion proof and vibration proof stainless steel resistors. Safety features include the Sephco “Triple Interlock” load protection system, guarding against fan cooling failure, airflow restriction, high temperature and fan reversal. Unique features of Sephco load banks include circuit breaker protection for each load group and full accessibility to switchgear components and resistors.

Installation of LS type load banks will ensure optimum reliable power from generators. Constant load maintained on generators will prevent wet stacking, cylinder bore glazing and reduce emissions.
