EPOWERSYS products

RPSu range. High Precision - High Stability Power Supply. 2 PPM. < 2 PPM Long term stability (8h). Zero Thermal Drift. 0 ppm/K, 25ºC stable operation with ±0.1 ºC deviation.ADC and burden resistor for the current digital control loop are located inside a peltier chamber to ensure temperature independent operation. DCCT Technology. The feedback measurement of the current control loop is carried out using a DCCT sensor with a linearity error lessthan 1 ppm. Vienna Rectifier. Active input filter with PFC = 1 in all operating range. LDO references. Digital converters ADC and DAC are powered by LDOs. This linear technology avoids commutations and noise. This means that the converter instrumentation has high accuracy and clean voltage. Power Flow Screen. The digital 7-inch display allows to monitor the complete power flow of the power supply. Active temperature monitoring. Key points temperature is monitored in the converter. Points such as semiconductors, high frequency transformer, input and output fans are controlled to ensure the correct operation of the device and to prevent possible failures. Multiple control modes. The power supply can be controlled in multiple modes, such as constant current, constant voltage, hybrid, constant power, analog reference for voltage or current or as a function generator for current, voltage or power. Remote sensing. Remote voltage sensing to avoid voltage drop in cables by measuring real voltage on the load. Long term data storage. RPSu stores many parameters in a database. Those parameters can be displayed on charts, user can choose which parameters to display. All parameters data are stored from the first day of operation of the RPSu. Those can be downloaded from USB port. Noise immunity. · Switching semiconductors are driven by means of an optical fiber digital transmitter, achieving the highest performance in terms of speed, bandwith, attenuation and noise immunity.· Optic fiber drivers.· The power supply uses a high frequency transformer designed to minimize the dispersed flow, preventing induced currents and noise generation. RPSu: EPOWER SYS range of high stability programmable DC power converters. Switched topology. Scientific research and industrial applications. High current output. Applications. Control modes. Accuracy and resolution. Real time PPM calculation. RPSu displays in real time accuracy in PPM for the present load in screen and in graph. This feature is especially useful for adjusting control loops. Power Flow Screen. Power Flow screen displays converter’s complete control status information in a unified screen. Models. Programmable DC Power Converters 750W - 12kW RPSu Series.

CDG 7000 is presently of standard use at CERN for testing all magnets in the accelerators and experimental lines of any type (normal conducting and superconducting, small and large). CDG 7000 is easy to use and you will save money. The insulation faults between turns are detected either by comparison of the reference’s coil waveform with the coil under test or by observing a change in the ringing frequency of the DUT. You will be able to see faults which you might be missing with your existing tester. You need at least 1µF and 2kV to detect some faults before a problem in operation. CDG 7000 is equipped with: USER-FRIENDLYNESS. You do not need high voltage skilled operators to use it.
