Resistor Banks versus Programmable Load

Resistor Banks versus Programmable Loads

Modern electronic devices are a few orders of magnitude more complex today than at the advent of the electronics industry.

Once we have moved past determining if something works, we become more concerned with why and how it fails.

The ability to stress your product beyond normal operating conditions is imperative to identifying design flaws and limitations – before your customer does. Can you achieve those adverse conditions and finely control/adjust them in a repeatable manner while collecting data using a resistor bank? Well, you can try.

The alternative solution is to go with the modern approach and utilize one of Intepro’s Programmable Electronic Loads. They provide a feature-rich environment designed for intuitive operation at cutting edge speed and performance specifications. What you achieve are fast and reliable results in a fully customizable test environment. For the energy savvy customer, we also offer our DC Loads with Regeneration (energy recycling). Instead of being dissipated as heat which then has to be cooled, loaded energy is synchronized and deposited back to the local mains at 93-95% Efficiency. The net result is less heat & fan noise, more energy savings. You will find a snapshot of our load offering below.
