High-Stability, Efficiency and Low-Noise performance in a single 19"-3U power converter!
The NGPS – New Generation Power Supply – series is a set of power converters that combines our know-how and technology together with the high-end ones of our partner OCEM - Power Electronics into a power supply with outstanding performance and functionalities.
High-efficiency, low-noise and extreme temperature and long-term stability, obtained by the use of a DCCT of the 0-FLUCS technology allow the NGPS units to be the perfect fit for high demanding applications – e.g. particle physics and medical accelerator magnets.
The control loops of current and voltage are performed via a combined FPGA – DSP – ARM technology that enables to obtain the desired dynamic response with any type of different load connected to the power unit.
The architecture allows to get rid of a precision DAC board and a power amplifier: less components, more reliability, less noise, better performances!
CUSTOMIZATION of output ratings is available upon request!
Temperature stabilization, Ethernet, Fast Interfacing and embedded Linux OS.
The NGPS power units have a temperature stabilized section internally that makes the ambient temperature variations almost negligble, reaching a typical Temperature Coefficient (TC) value below 0.0001 %/°C.
The interfacing to the unit is straightforward: the standard fast interface is a 10/100/1000 TCP-IP Ethernet which gives industrial reliability and performance.
An ultra-fast interface used also to parallel units, is available on the front panel as SFP slot that enables users to digitally run the power unit at an outstanding 10-kHz update rate.
The embedded Linux OS gives maximum flexibility, creating a higher-level of interfacing to the external world. This also allows implementing customer routines and scripts on the unit directly.
Waveform, Oscilloscope, Trigger Input, Remote Sensing and Analog Control capability.
The NGPS also has the capability of having its operation synchronized to external events by using an external trigger signal fed via a BNC connector on the rear side.
Remote sensing terminals are also present in order to compensate external voltage drops when running the power unit in C.V. (Constant Voltage) mode - e.g. on the resistance of the cables - thus guaranteeing that the voltage at the load is exactly at the desired value.
An extra analog input, rated at 0 - 10 V and bandwidth at 1 kHz, is also provided for compatibilty with older systems where a DAC was used in order to control the power unit. This feature gives the possibility of gradually upgrading the setups from the older one to the newer ones.
Current and voltage waveforms can also be performed by the NGPS using its capability of easily pre-loading a point-by-point desired waveform and then executing it once needed. In cases where ramping is necessary this feature is extremely useful and improves reliabilty on timings respect to the standard solutions.
Parallel up to 4 units for higher current and higher power ratings.
The NGPS power converters can be easily connected together and by configuring a master device and multiple slaves, higher power ratings can be reached maintaining the same level of stability and TC.
An active current balancing is performed using the fast SFP connections: each module can run at its maximum ratings without any de-rating of current and/or voltage.
The parallel connection is performed at the output terminals and the units simply "communicate" together via the fast SFP interface present on the front panel (see accessories for paralleling in the ordering options).
This allows using the NGPS as the basic building block for more powerful and complex system, still operating the power supply "bundle" as a single logical unit via a single communication interface.
Paralleling four (4) NGPS 100-100 or four (4) NGPS 200-50 units, for example, allows obtaining equivalent power converters of 400 A / 100 V and 800 A / 50 V respectively.
