2. Getting Started

The DBx Module combines ultra-stable fluxgate direct-current current transformer (DCCT) with temperature stabilized controls to drive a MagnaDC programmable power supply at ultra-high stability and precision levels.

To get started, both communication and power connections need to be made to interconnect the DBx Module and the MagnaDC power supply. In addition, the MagnaDC power supply needs to be configured for external inputs. This section provides getting started guide for the various DBx Module Configurations.

2.1. Introduction

DBx Module Configurations A1 and B1 are provided with copper bus bars with threaded inserts for the DC input and DC output connections. In these configurations, the DC power supply output connects to the DBx Module’s DC input and all current sensing is done internal to the DBx Module. The load / device under test gets connected to the DBx Module’s DC output bus bars. DBx Module Configuration C1 uses an external DCCT with a control signal providing feedback to the DBx Module via its external user I/O connector. In all configurations, so that the DBx Module can control the power supply, a provided cable connects the DBx Module’s interface connector to the power supply’s JS1 37-pin external user I/O connector.

Digital programming of set points, trip points, and slew rates are performed using the DBx Module via front panel knob or keypad, front panel up-down arrows for highly granual single-bit control, or using the computer interface connections via provided MagnaWEB software or user defined software using SCPI commands. Included communication interfaces include RS485 and front/rear USB with optional LXI TCP/IP Ethernet or EtherNet/IP.
