Product Description


Compact and Lightweight design that is ideal for moving from job site to job site or within your facility.

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

2.Main features and advantages

  1. Power consumption components adopt special alloy resistor, high-temperature resisting, small thermal drift, safe and reliable. Running temperature is 1/3 of design temperature.
  2. Industrial heavy duty blower, horizontal inlet, vertical exhaust, low noise.
  3. Weather-proof structure, suitable for abominable environment.
  4. Multiple control mode: (1)Local panel control, (2)Remote control box/cabinet(3) Intelligent control(by PC software)
  5. Multiple protection function: overvoltage, overcurrent, overheat, low over blowing rate, blower overheat, blower phase sequence reverse protection, smoke alarm etc.
  6. Integrated design, easy to installation.
