Repeated Charge Discharge Test Set
-
The IS 13341 : 1992 has laid down the requirements for Ageing Test, Self-Healing Test and Destruction Test on Shunt Capacitors of the self healing type for AC Power Systems. The Ageing Test is to be performed at a specified voltage of 1.25 times the rated voltage for 750 hours. The test is to be followed with a repeated discharge cycle test which involves charging of the capacitor to a DC voltage and discharge of the same through an Inductance. Sivananda Electronics has developed this equipment for the benefit of capacitor manufacturers, for the first time in India.

Modern Prepolarized Precision Condenser Microphones & Preamplifiers
-
Modern prepolarized microphones are designed with newer technology than traditional externally polarized microphones. Prepolarized microphones have many advantages over the externally polarized models. They use ICP® power circuitry invented for sensors by PCB®. By applying a polymer coating to the top of the backplate and embedding a charge on it, expensive 200V power supplies can be eliminated and 2-20 mA constant current supplies or signal conditioners can be used as the power source.

High Temperature Charge Mode Accelerometers
-
Charge mode output accelerometers from PCB® use piezo-ceramic sensing elements that output an electrostatic charge signal proportional to the applied acceleration. These sensors can operate at extremely high temperatures because they do not contain the built-in signal conditioning electronics that limit the temperature range of ICP® accelerometers. Charge mode sensors are used in the testing of gas and steam turbines, jet engines, high power motors, exhaust systems and automobile engines where temperatures can range from 500° F (260° C) to 1200° F (649° C).

Charge Controller
-
The intelligence of an AC charging station or an AC charging infrastructure is largely determined by the charge controller used. A smart charge controller has the primary task of controlling and monitoring the charging process of an electrical vehicle.The features that characterise a smart charge controller include communication with a backend system and the associated authorisation of users, as well as the efficient distribution of load currents by means of dynamic load management to prevent an overload of the existing AC system.

Charge Integrator Amplifiers
AD8488
-
Analog Devices’ charge integrator amplifiers convert the charge acquired by X-ray or photodiode detectors to a voltage. The channels are composed of CMOS transistors, using typical high input impedance CMOS gates. The integrators generate charge dependent voltages using a range of selectable capacitance values that accommodate a broad range of input charge values. The integrators are followed by single-ended input to differential output voltage amplifiers where offset and low frequency noise voltages are subtracted from the input voltages.
