Construction | Built to Last

The LP500 is constructed of galvanized steel with the highest quality durable powder-coat paint finish. Portability and ease of positioning are provided with moving handles and heavy-duty casters. Tie-down provisions allow for secure transportation to and from job sites.

Quick Connects | When Time Matters

The LP500 features a set of fully-rated, industry exclusive Cam-Lok power connectors which are color coded for operator safety and ease-of-phase identification. Protective snap-back covers provide added safety during storage and operation.


PowerDyne™ | When Quality Matters

PowerDyne™ Resistors are the most rugged in the industry and can handle the rigors of over-the-road use. They are fully supported across their entire length within the air stream by stainless steel support rods which are insulated with heavy-duty, high-temperature ceramic insulators. Change in resistance is minimized by maintaining conservative resistor designs.

Control Power Transformer

All control circuits are powered by an integral 400:115 Volt AC, 1-Phase, 50 Hertz Control Power Transformer which is wired to the blower motor circuit and is both primary and secondary fused.

Control Power


Cooling System

  • Integrally mounted blower motor with high-performance, direct-driven fan blade delivers the required airflow volume (CFM) for cooling resistor load elements
  • Motor circuit is short-circuit protected by current-limiting fuses and thermally protected by overload relays

The LP500 50Hz Portable Load Bank

Rugged, portable design meets the demand of daily transit and testing.

The LP500 Portable Indoor Load Bank offers the most robust, high-capacity design in the industry. LBD is setting the standard with intelligent operator controls, safety indication layouts, adjustable load step resolution, and lightweight designs. The LP500 is the perfect solution for regularly scheduled maintenance testing and commissioning of mission-critical standby emergency power systems.


Digital Power Meter

A fully equipped, 3-phase Digital Power Metering System that measures a standard range of 16 load parameters. Includes RS485 (Modbus protocol) for remote reading - compatible with PC, PLC, and data loggers.


Operator Protection | When Safety Matters

The LP500 comes equipped with an Emergency-Stop push button allowing the operator to take the unit off-line should a critical hard-stop condition occur. Branch circuit fuse protection provides short-circuit fault protection of all load steps eliminating the potential for catastrophic failure. Blower On, Motor Overload, Air-Flow Failure, and Over-temperature circuits disable all load steps during a fault condition with operator visual indicators. The Load Dump circuit provides the operator visual indication if all load steps have been removed

Operator Controls

  • Emergency Stop (E-Stop)
  • Illuminated Main Power On/Off switch
  • Fan-Phase Reversal switch
  • Master Load On/Off switch
  • Fault condition smart indicators
  • Individual Load Step Switches
