Capacitor charging HV modules add reduced temperature coefficient option

January 30, 2013 // By Paul Buckley
UltraVolt, Inc., has refined the company's of power supplies product line by offering the -25 PPM option on its High Power C Series and High Power 8C-30C Series.

The -25PPM option has been available on product lines such as the A Series high-voltage bias power supply (from 4 W to 30 W and 0 to 62 V to 40 kV), the high performance PPM-level ripple and regulation E Series, and most recently on the smaller size version of the A the AA Series.

Now, High Power C Series and High Power 8C-30C Series high-voltage power supply modules from 60 W to 250 W and 0 to 125 V through 30k V featuring the -25 PPM option will provide an improved temperature coefficient for customers who have critical applications in variable temperature environments. High voltage power supplies with this option maintain a 25 ppm temperature coefficient on both the output voltage and output voltage monitor.

In addition, the modules will provide 0 to+5 V or 0 to +10 V compensated reference. These references have 0.05% accuracy and 5ppm per °C temperature coefficient.

The addition of this option to these series broadens the availability of the -25PPM option to high voltage modules with an output voltage of 0 to 62 V through 0 to 40 kV, configured for either biasing or cap-charging applications. As a result of UltraVolt’s product standardization, units featuring the -25 PPM option conform to the standard package size. This makes them ideal for plug-in replacement in current designs, as well as use in new designs – especially when used in conjunction with the new –I5/-I10 digital-ready interface option for quick integration with DAC & ADC solutions using a PC, PLC, or MicroController.

Modules featuring the -25 PPM Option are available with a lead time of 4-5 weeks.
