Field Effect Rectifiers
-
ST field-effect rectifier diodes (FERD) help improve designs with new versions focusing on trade-off upgrades. Field-effect rectifier diodes belong to our STPOWER family. The design of the FERDs has allowed both a decrease in the voltage drop and a decrease in the leakage current temperature coefficient. As a result, the runaway safety margin is improved and maybe beyond the typical safety margin of Schottky barrier diodes.

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.

Earth Contact Resistance Tester
-
SCR ELEKTRONIKS have developed an equipment namely Earth Contact Resistance Tester to test the appliance. To ensure the safety of operator it is essential that the Earth path (connection) should offer minimum impedance to by pass short circuit Current to Earth. This is ensured by measuring Resistance of the Earth path by passing heavy Current say 25 A. The Earth Contact Resistance Tester essentially comprises of a Variable Current source with digital Ammeter to measure the Current supplied. The Voltage drop across the Earth path is measured with a digital Voltmeter. Optionally for a particular Current (25 A) the meter can be calibrated in terms of Resistance. A timer is provided to switch off the Current after the Set Time.
