The DBx Module is a performance-enhancing series-connected add-on module for MagnaDC programmable DC power supplies, delivering ultra-high stability, low ripple, high precision and high accuracy, with voltage, current, and power control modes. The combination of the two products provides a broad range of magnet power supply solutions for high-energy physics and medical applications, including driving dipole, quadrupole, and steering magnets, as well as powering coils to establish stable magnetic fields. In addition, the high power density coupled with the high accuracy and low ripple characteristics make the combined solution ideal for ATE calibration applications.

Ultra-Stable, High Accuracy, and High Resolution. An ultra-stable fluxgate direct-current current transformer (DCCT) is used to take high accuracy isolated measurements from a series connection with the power supply’s DC output. This ultra-stable transducer, combined with the DBx Module’s low temperature drift resistors and temperature stabilized digital programming circuit, provides highly granulated programming (18-bit) and readback (24-bit), and enables long-term stability less than 5 ppm. Critical components are carefully laid out within a specially designed temperature compartment to accelerate the time to temperature stabilization.

Configurations of DBx Module

The DBx Module is offered in three different configurations—A1, B1, and C1—differing in maximum current capability and internal stages.

The DBx Module Configuration A1 contains all stages, including the linear regulator, differential- and common-mode DC EMI filters, temperature-stabilized ultra-high stability controller, and DCCT. Configuration A occupies a 1U (1.75” high) rack-mount enclosure and is available for voltages from 10 Vdc to 1,000 Vdc and three different max current ratings, at 75 Adc, 150 Adc, and 225 Adc.

The DBx Module Configuration B1 is intended for applications that do not require additional DC filtering and contains only the temperature-stabilized ultra-high stability controller and DCCT. Configuration B occupies a 1U rack-mount enclosure and is available for voltages from 10 Vdc to 1,000 Vdc and three different max current ratings, at 75 Adc, 150 Adc, and 225 Adc.

The DBx Module Configuration C1 is intended for high-current applications, where the 1U rack-mount enclosure contains only the temperature-stabilized ultra-high stability controller, with a provided external DCCT that ties into the DBx Module through a rear connector. Configuration C is available for voltages from 10 Vdc to 1,000 Vdc and max current ratings from 300 Adc to 6,000 Adc.

Model Ordering Guide

DBx Module models are defined by the configuration type and number, the maximum voltage rating, and the maximum current rating. Any voltage from Magna-Power's standard Magna DC power supply offering is available, from 10 Vdc to 1,000 Vdc. The DBx Module resolution step size and calibration is a function of its maximum ratings, therefore it's recommend to specify a model most closely matched to the requirement.
