Avtron's complete line of portable resistive load banks ranges in size from 10KW to 700KW. For larger ratings, Avtron can provide trailer mounted models to satisfy most load testing requirements at remote sites.

Built to resist vibration encountered during transportation, Avtron portable load banks are lightweight, compact, reliable, and save money because they are built to last.

These Avtron units feature durable Helidyne (TM) resistive elements cooled by high volume blower assemblies and integral operator control panels. Switches on the control panel actuate 120VAC contactors to safely isolate the operator from high voltage circuits. Control power can be derived from the power source under test, or from an external 120VAC source. The ADMS (TM) Digital Metering system is standard on units rated 25 KW or higher.

Avtron's portable load banks are constructed using heavy gauge aluminized steel for years of reliable service. These units are fitted with lockable casters or rubber shock mount feet for easy movement from one test site to another using common pickup trucks or vans.

Optional equipment available includes:

  • Power cable set with connectors
  • Heavy Duty Shipping Case (standard on Liberty, optional on Freedom)

The Avtron Liberty Load Bank (LPH series) is available in three standard versions including 55 KW at 240 or 480 VAC, 3-phase, 60 Hz, 25 KW at 120/240 VAC, 1-phase, 60 Hz, and 75 KW at 240 VAC, 1-phase, 60 Hz. At only 69 pounds, it is light enough to be easily moved and transported by one technician, and rugged enough to stand up to years of reliable service. The load bank comes standard with a hard-cover protective travel case on casters with a telescoping handle.

The Avtron Minuteman Load Bank (LPC series) provides up to 100 KW resistive load at 480 VAC or 240 VAC, 3-phase, 60 Hz. The unit will also provide a full 80 KW at 208 VAC, 3-Phase, 60 Hz. The fully-rated, quick-connect load terminals and simple manual operation allows the load bank to be set up and operated by a single technician, saving valuable time in the field. Weighing only 78 pounds, this versatile load bank is lightweight and ultra-compact. A 10 foot Load Cable set and rugged hard shell travel case (with casters and telescoping handle) are included with the Minuteman 100.

The Avtron Freedom Load Bank (LPH series) is rated 100 KW at 480 VAC, 3-Phase, 60 Hz and 93.75 KW at 240 VAC, 3-Phase, 60 Hz. Designed for continuous operation, this Avtron Load Bank gives users the Freedom of a high-capacity load in a lightweight and ultra-compact package. Weighing only 105 pounds, this load bank is less than half the weight and size of traditional load banks of similar capacity. Built for indoor operation, the Freedom load bank is ideal for field testing Uninterruptible Power Supplies (UPS) and small AC generators.


Hand Carried Portable Load Banks

^ Back to Top

Standard Models

Avtron produces three small portable load banks. The model K490 is an AC load bank designed for indoor use that provides up to 10KW load at 120 or 240 VAC. Due to its small size, the K490 is easily transported to any job site.

For DC loading in a hand carried package, Avtron offers the model K492. This unit provides up to 150 Amperes loading capacity for testing UPS and other DC power sources at either 26 or 52 Volts DC. This unit also does not require special tools.

These units are "the load banks of choice" as they provide the right mix of transportability, ease of use, and reliable Avtron construction.

  • K580 (1000-1250 KW)
  • K580HC (2000 KW, 2500KW)
  • LTV (1500-3000 KW)
  • LCV (2500 KW; 1875 KVAR)

Optional features available on Avtron trailer mounted units:

  • Cable Reels
  • Cable Storage Box
  • Load Cables

Avtron offers an extensive line of load bank trailer packages for high power over the road, mobile testing at multiple sites. Resistive, Reactive, or DC models are available. The load bank can be supplied mounted to a heavy duty, dual-axle, DOT road legal trailer, or supplied “loose” and “trailer-ready” for easy installation on your own locally purchased trailer. Options include load bank quick-disconnect power connectors, load cable storage box, cable reels, and trailer hydraulic surge brakes (electric brakes are standard).

The K580 load bank is a low-profile horizontal airflow type frame that is available in ratings of 1000 KW or 1250 KW. The K580D is available in ratings of 2000 and 2500 KW.

With the introduction of larger generator sets in the marketplace, the need has grown for very high capacity portable load banks for start up and maintenance testing. To meet this need, Avtron has designed a trailer mounted load bank package with load capacity ratings up to 3000 KW at 480 VAC, 3 phase, 60 Hz. The vertical airflow design offers increased load handling capability in a single stand-alone unit.

ADMS - Advance Digital Monitoring System
ADMS
For further details, see product sales bulletin * ADMS

The Avtron Advanced Digital Monitoring System (ADMS) represents the new standard in Load Bank Instrumentation allowing Real-Time Data Acquisition and Data Logging from customer laptop PC, or PDA.

ADMS is a Multi-Function Digital Power Meter that provides 3-line digital display of Voltage, Current, Frequency, and Power Measurements. Unlike conventional meters, the large 0.56" extra-bright LED's allow the user to clearly monitor the meter display under any condition 24/7. The meter faceplate features an optical IrDA port for data transfer and comes complete with an IrDA/USB adapter for "plug and play" convenience. Meter parameters are captured from the IrDA port and can be downloaded to your PC or PDA. The Communicator EXT software provides Real-Time Monitoring and Data Acquisition from your laptop PC, allowing the user to display meter parameters in Real-Time Trending or Real-Time Data Logging format. Data can automatically be recorded and saved to your computer which can be easily imported into a Windows spreadsheet.

With faceplate, PC or PDA monitoring, this rugged metering system is designed to save both time and money. It virtually eliminates the need to manually record load bank values during a load test.

The ADMS (Advanced Digital Monitoring System) is offered as a standard feature for Avtron Portable Load Banks (Liberty-55, Freedom-100, Millennium-200/250/400, Patriot-700), as well as over the road trailer load banks ranging from 500-3000 KW.
