AC & DC Aging Test Equipment for Arrester Valve Plate
-
Shanghai Guantu Technology Co., Ltd.
The arrester is usually connected between the live wire and the ground, and is connected in parallel with the protected equipment. When the overvoltage value reaches the specified operating voltage, the arrester will act immediately, flow the charge, limit the overvoltage amplitude, and protect the insulation of the equipment; when the voltage value is normal, the arrester will quickly return to its original state to ensure the normal power supply of the system.

Programmable DC Electronic Loads (conventional and regenerative)
-
Elektro-Automatik GmbH & Co.KG
Our programmable electronic loads are composed of an optimum mix of analogue- and digital technology (µ-controller/FPGA based). By combination of standardised electronic platforms out of a modular structure, we generate a large portfolio of electronic-load series, perfectly adapted in power, function, performance and cost to the numerous applications in industrial environment and R&D. EA programmable electronic loads are available in conventional technology (heat dissipating) and as “regenerative” loads. The latter allows, specifically under long-term testing condition (e.g. battery discharging) a full amortisation of its invested value by its energy-saving capability, similar as with Photovoltaic installations.

"Soft Grid" and Parallel Operation AC Generator Excitation Regulator
svrsp
-
The Kinetics model SVRSP Exciter/Regulator rectifier is designed and rated in capacity and operating parameters for the application of exciting the DC fields on an AC generator operating in parallel with other AC generators and the power system is a "soft system" in relation to loading. A "soft system" is a generating system that may not be able to sustain the rated AC voltage under impulse/step loading conditions and results in voltage reduction when tan impulse/step load is applied.

Stand Alone/ Bench Top Load Cell Amplifier/ Conditioner Module
MODEL TMO-2A
-
The TMO-2A Transducer Modules is a complete differential amplifier/signal conditioners with self contained power. The unit provide excitation, balance and span adjustment via precision 10 turn pots, and shunt calibration necessary to couple a user supplied bridge type transducer to an indicating instrument. Zero to full scale output is specified at 4-20 mA. The TMO-2A provides a floating shunt calibration circuit which applies calibration at the transducer, thereby eliminating errors due to line losses. The excitation supply incorporates a Wagner Ground to greatly improve Common Mode Rejection. The factory set bandwidth of the module is narrow to improve stability. The removal of a single capacitor will increase the frequency response DC to 60K Hz for dynamic data applications.
