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.
