EPOWERSYS - Model RPSu Series -Superconducting Magnets

RPSu range. Superconducting magnets. Highest current output in the market in ½ 4U Standard Converter. RPSu can deliver up to 500A of maximum current and 10V or 20V voltage, up to 12kW of maximum power. 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 less than 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. The power supply uses a high frequency transformer designed to minimize the dispersed flow, preventing induced currents and noise generation.
