Loading Devices

Available with IEC/ISO 17025 Certificate of Calibration
Sometimes you may need additional loading for abnormal testing (i.e. overload test). Other times, you may need additional loading to simulate worst case normal operation conditions (i.e. input test, temperature test). No matter what your application, we have the loading device to fit your needs!

TECH NOTE: Be sure to request our outline titled "Selecting Loads" for assistance in determining the proper rated device for your application.

EXCLUSIVE! NEW! A SAFE and EFFICIENT alternative!

Instead of building a test rig with innumerable wires, and risking equipment damage or fire hazard, ED&D has designed and developed a cutting-edge line of Resistive Load Banks.
  • Built-in fans provide sufficient cooling
  • Self-contained unit eliminates hazards due to exposed wiring
  • Fine tuning mechanism allows for ultra precise measurements
  • Units are on casters, providing a portable test station!



Grid, wirewound, and helicoil wire wound resistor options for different ohm / wattage / amp needs. Open screened or louvered racks available. Provide your ohm, wattage and amperage specifications for quotation.

Product Details

Nichrome wire resistive loads are perfect for loading higher voltages, especially line voltages! Open frame design.
Model Voltage Current
ACL-05 120/240V 5.0/2.5A
ACL-10 120/240V 10/5.0A
ACL-15 120/240V 15/7.5A
ACL-20 120/240V 20/10A
above: The PEL Series is perfect for loading power supplies
Product Details

Electronic loads can greatly simplify the loading process. Constant voltage, constant current and constant resistance settings allow you to simply dial in your desired loading. Integral display gives direct readout. Perfect for loading power supplies. Incorporate overload protection circuitry. Also includes RS-232 and IEEE488 interfaces. Contact ED&D, Inc. for additional details and specifications.
above: Adjustable power resistors
Product Details

Rheostats are adjustable power resistors. Perfect for low voltage applications (i.e. 5V, 12V, 24V). The low cost option for loading. Another benefit is that they can be adjusted under load. Knobs and stands available.
