Electra
Portable Load Bank
The Simplex Electra is
a very large capacity, high performance Portable Load Bank designed
to provide the manufacturers, distributors and users of large
AC generators and UPS systems with sophisticated testing capability.
The Electra provides 460KW, 560KW or 660 of resistive
load at both 240V and 480V, 3-phase. It can be applied at any
AC voltage to 480V AC, 50-60-400 Hertz, single or 3-phase. Load
step resolution is 5KW.
The Electra is a totally self-contained testing system.
It includes all resistive load elements, load control devices,
load element circuit protective devices, connection cable set,
cooling system, malfunction detection system, control power supply
and test instrumentation.
Principal Sub-Systems
Load Elements: Simplex “Powr-Web” chromium
alloy, open wire, continuously supported, power resistor.
Load Control: 3-Pole magnetic contactors.
Load Element Circuit Protection: Branch circuit fuses.
One set of fuses each 50KW branch. Fuses are current limiting
type, 200,000 AIC, 600V, enabling safe use on large generating
or UPS system.
Cooling System: 3-phase, direct-drive fan, 12,500 CFM.
Malfunction Detection System: Protection against fan failure,
high exhaust air temperature, high intake air temperature, overvoltage
and fan reversal.
Control Power Supply: Dual voltage control power transformer
with supply power switchable to internal (generator) or external.
Test Instrumentation: 3½”, +/- 2% accuracy
panel meters. Options available.
Remote Control: Load control switch panel removable for
remote operation. Connection plugs will accept optional remote
control cables.
Connection: 12’ connection cable set including 3-phase
power cables, ground cable and external control power cord, stored
behind hinged door in rear compartment.
