Fonte de Bancada CC de Altíssima Estabilidade Chroma 62075H-30N

Chroma’s new 62075H-30N ultra-high stability DC power supply offers many unique advantages for magnet power supply systems in synchrotron applications.

These advantages include an excellent current stability of 1.25mA/0.5 hour and 2.5mA/8 hour, extremely low current ripple of 2.5mA, current reproducible within 10mA, precision setting and readback of output current via 20 bit DAC/24 bit ADC.

The 62075H-30N output power has a maximum 7.5kW/30V/250A power module with a 4U height cabinet that can be connected easily as either master or slave with three units to 22.5kW/30V/750A in parallel or two units to 15kW/60V/250A in series and operated as a standalone unit via system bus.

The 62075H-30N provides stable DC output current source and power for precision measurement. It offers an advanced 250A/30V ultra high-stable ±10 ppm (current stability ±1.25 mA) with high efficiency and high power factor in compliance with energy savings. In addition it has a 20 bit digital control with bright vacuum fluorescent display readout.

The 62075H-30N ultra-high stability power supply is very easy to operate from either the front panel keypad or the remote controller via USB (standard) and Ethernet/LXI (optional). Its compact size of only 4U can be used either on a bench or be installed into a standard rack without difficulty.

Features include current mode with dual loops control. It is able to provide a stable and fast output response providing excellent protection for different load variations.

The self-diagnosis routines and full protection against voltage phase loss, over/under voltage at input, over voltage/current at output, over power, over temperature, fan fail, and remote inhibit ensure the quality and reliability of the instrument for even the most demanding magnet power supply system in synchrotron applications.

High-Precision DC Current With Ultra High Stability

The 62075H-30N offers a high power density envelop of 7.5kW in 4U that delivers high-precision DC current with ultra high stability 10ppm and extremely low output ripple, excellent line and load regulation, and fast transient response. With the combination of wide range of voltage (0-60V) and current (0-750A), this power supply is ideal for storage ring quadrupole and sextupole magnets in synchrotron application.


Master / Slave Parallel And Series Operation As Standalone Unit

When high power is required, it is common to connect two or more power supplies in parallel or series. The 62075H-30N supply has a smart Master/Slave control mode making series/parallel operation fast and simple. In this mode, the master scales values and downloads data to slave units that makes programming simple and power control run automatically.


Remote Control And Digitizing Trigger Data

The 62075H-30N provides a digitizing function to record the transient current waveform via remote USB and Ethernet interface. It can set the output current level and digitized parameters following the sample time, sample point, trigger source and trig point, etc. The power supply saved data function can be used easily to detect errors and prompt warning message when the operation stops.
