2 DESCRIPTION AND SPECIFICATION
Simplex Saturn load banks are precision test instruments
designed to apply a selectable load to a power source and measure
the source’s response. ey are used for routine maintenance
exercise to ensure the long-term reliability and readiness of the
standby generator. Load banks can also eliminate the detrimental
eects of unloaded operation of diesel engine generators as well
as prevent damage from reverse power generation.
Saturn load banks are available in models ranging from 1400
kilowatts up to 3200 kilowatts. All standard Saturn models have
a step resolution of 25 kilowatts.
Saturn load banks feature a Human-Machine Interface
(HMI) touchscreen, which controls load bank operation and
displays the unit’s status. With the HMI, the operator can apply
a desired load and measure the response of the test source.
e load bank can also be integrated into your facility’s BMS/
BAS system via standard Modbus RS-485 or optional Modbus
TCP/IP, as well as a set of dry contacts for status reporting.
Saturn load banks are cooled by forced air, delivered by an
aluminum fan blade directly driven by a TEFC motor. e air is
brought in on the bottom of the load bank and expelled through the
top. Optional equipment allows the exhaust to be driven through a
customer-installed duct, providing for indoor installation.
e load system comprises independently controlled Simplex
Powr-Web resistors, which have been designed specically for
use in load bank systems. e load elements are supported by
high-temperature, ceramic-clad, stainless-steel rods across their
entire length, virtually eliminating element-to-element short
circuits. e elements are arrayed in discrete trays, which are
independently serviceable.
e Saturn is protected by sensors to ensure that the load
bank is suciently cooled and that the exhaust does not exceed a
safe temperature, which could damage the load bank or present
a safety hazard to the operator. When a failure occurs, the safety
system immediately removes the load to protect the equipment
from permanent damage.
