Custom Designs? We build to order!

Custom Resistors For Your Next Project Riedon can modify existing power resistor designs to fit many special applications. For example, it is relatively easy to imbed one of our standard wirewound power resistors into a custom case. Our custom capability is somewhat...

Divide and Conquer!

High Voltage Dividers High voltage dividers are used to scale down a high voltage for any number of reasons including: feedback for power regulation, or simplified monitoring. Potentiometric ratios as high as 1000:1 or even higher are not uncommon. Voltage divider...

The view from up there must be amazing!

Current Sense Resistors High current sensing is where a low ohmic precision resistor is used in series with the load. To determine the current one measures the voltage drop across the resistor. This is the same principal used by a shunt ammeter. The dilemma facing the...

Striking a Balance!

Riedon’s Balancing Resistors Balancing resistors provide a way for sharing a load between two or more DC-DC converters or power transistors. Using two smaller devices in parallel may have cost, thermal, or physical advantages when compared to one device of...

Relax. No need to inrush.

Inrush limiting resistors Inrush limiting resistors of a few Ohms or less in series with the AC line can address a problem with AC-DC converters where a large surge current may occur as the device powers up and the bulk storage capacitors initially charge.  One...
