MegaBank™ MB555 is an extension to Mosebach's load bank family, building on the
strengths of the original MegaBank™. We have adapted the blower from a tube-axial to a centrifugal design, which offers more uniform airflow at a reduced sound level.

The MegaBank™ MB555 is a continuous duty, lightweight load bank that is easy to transport, set up and operate.

The MegaBank™ MB555 can be used for testing generators, UPS systems and static
inverters up to 555 kW.

Standard voltages available are 480/240/208 3 phase, 60 Hz. A 400 Hz option is also available. 600V and other voltage versions are also available.

Mosebach has a long history in the rail and mining industries, where its resistors are used in large power (4,000 kW typical) dynamic brake systems. Thousands of our resistors are used daily in locomotives and giant mining trucks in the USA and around the world.

Mosebach has taken its expertise in large power resistors and applied it to these smaller power load banks. Specifically, we have developed the SlimLine™ resistor, which has superior insulation and heat transfer capabilities. The resistor element is a stamped stainless steel plate held in place with mica insulators.

There is no ceramic to shatter, no metal rods to short-circuit, and no bailing wire to cause a cascade failure of the load bank's resistors.

FEATURES:

Mechanical
· Rugged steel enclosure with scratch resistant powder-coat paint system.
· Portable, lightweight construction with casters and lift truck channels, making it
  easy to maneuver.

Cooling
· High-volume, low-noise centrifugal blower with horizontal discharge.

Electrical
· Digital meter (50/60 Hz) to indicate volts, amps, kW, frequency, and more. Option
  for 400 Hz or both 50/60 and 400. Option for data logging capability.
· Voltage detection system ensures that the load bank auto-connects itself to match
  the applied voltage.
· Switches for system on/off, blower on/off, and steps on/off.
· Test jacks for voltages.
· Airflow and overtemperature indication lamps.
· Steps are controlled by magnetic contactors.
· Power circuit fuses (optional).
· Control power from the bus or customer supplied. Control circuit fuses are included
  to protect contactor coils and meter, and a motor starter for the blower.
· Customer connection is via cam-lock terminals for easy connect and disconnect.
