DC Filter Inductors
Osborne DC filter inductors (aka filter chokes) are commonly used in AC to DC conversion circuits to present an inductive voltage drop to the AC component of rectified current. This inductive voltage drop acts as a filter. Osborne designs filter inductors to components to function effectively (without saturation) in the presence of the DC current. Osborne will work with you to mitigate the impact of ripple frequency in conversion circuits. Every Osborne DC filter choke is designed for high performance with special consideration given to your circuit´s power supply frequency and conversion configuration.

Scanning Vibrating Electrode Technique
VS-SVET
The Scanning Vibrating Electrode Technique uses a single wire to measures voltage drop in solution. This voltage drop is a result of local current at the surface of a sample. Measuring this voltage in solution images the current at the sample surface. Current can be naturally occurring from a corrosion or biological process, or the current can be externally controlled using a galvanostat.

SparkFun Current Sensor Breakout
INA169
The INA169 is a “high-side current monitor,” which means that you place a resistor (a “shunt resistor”) on the positive power rail and the INA169 measures the voltage drop across that resistor. The INA169 outputs a small current based on the measured voltage drop. If you place a resistor from the output of the INA169 to ground, you can measure the voltage at the output.

Electrical Safety Test Equipment
Making a product “safe” requires an understanding of “hazards” that exist in each electrical product. Electrical shock is one of the four fundamental hazards. Because of that, it must be a part of any product electrical safety evaluation. Even though a product requires an electrical power source and uses electrical or electronic components, it should not present an electrical shock hazard to the user.Ground bond or earth continuity testing prevents electrical shock hazards. Similarly to a fault to earth, test instruments generate a high current. The standard requires that the resistance between protective earth and any conductive surface on the equipment does not exceed 0,1 Ohm. The test is performed by applying a DC current between the conductive surface and protective earth. By measuring the voltage drop, it calculates the resistance.RMO-E instruments are ideal for testing the protective bonding (grounding) of equipment following the standard IEC 61010-1. Applying current up to the value of 100 A and the ability to provide in the Contin menu (continuous operation) test current for the pre-set test duration (equal or exceeding 1 min) gives a user a possibility to easily check the protective bonding/grounding of the equipment. The full load voltage of 12 V assures proper measurement and accurate result. Finally, an instrument displays pass/fail classification according to user-preset parameters.
