高性能即插即用主从控制
通用接口设备47（UID47）旨在大幅简化MagnaDC可编程直流电源的主从配置过程。该设备包含配置Magna-Power直流电源所需的D-Sub通信电缆、连接器及电路，支持主从并联或串联运行。主从并联运行允许两台或多台电源连接后均等分配输出电流。主从串联运行允许两台或多台电源连接后均等分配输出电压。
UID47上额外的37针扩展连接器直接与主电源对应，使主从系统仍可通过模拟-数字用户I/O进行控制和监测。UID47还在印刷电路板上预留了用于互连导线和放置特定用户应用组件的区域，可连接至10针用户扩展连接器。

One UID is required for every slave power supply in the system.
UID46 — Analog Reference Control
[IMAGE: diagram_uid46_enclosure.eps]
The UID46 drives slave units through their 0-10 V external analog references, using the master's own monitor signals as the set point source. This method tightly matches output sharing between units, making the UID46 the recommended choice for current mode control applications and for high-current systems — such as large electromagnet and superconducting magnet loads — where current imbalance between units must be minimized. In current mode control, transient response is identical to the UID47 and UID53.

UID47 — Gate Driver Control
[IMAGE: diagram_uid47_enclosure.eps]
The UID47 configures the master power supply to directly control the gate drivers of its slave units. With a single control loop commanding every unit, the UID47 delivers the fastest transient response performance, making it the general-purpose choice for most master/slave systems.

UID53 — Gate Driver Control + BDx/DBx Module Breakout
[IMAGE: diagram_uid53_enclosure.eps]
The UID53 provides everything in the UID47, plus a dedicated 37-pin breakout connector (JR5) that carries the power supply interface signals required by Magna-Power's BDx and DBx Modules. In a master/slave system the power supply's user I/O connector is occupied by the UID cable — the UID53's breakout and included 37-pin to 15-pin interface cable let a BDx or DBx Module integrate with the power supply while it remains part of the master/slave configuration.

In every configuration, the total output of the system matches the programmed value; a two-unit parallel system delivers twice the current programmed on the master. The comparison above describes only how that total divides between units.
Parallel operation connects two or more power supplies for a total output current equal to the sum of the individual units, with equal current sharing under all load conditions and complete control from the master.
Series operation connects two or more power supplies for a total output voltage equal to the sum of the individual units, with equal voltage sharing under all load conditions.
Systems scale to three or more supplies by daisy-chaining additional UID units, so master control and monitoring signals route automatically to every slave. Each UID ships factory-configured for parallel operation; switching to series requires only moving the internal jumper.
BDx/DBx Module integration (UID53): blocking diode and high-stability modules connect directly to the UID53's breakout connector, preserving full module protection features, including power supply shutdown on module thermal alarm, inside a master/slave system.
Every UID doubles as a development platform for custom control and monitoring. All 37 power supply interface signals are broken out to labeled pad areas on the printed circuit board, a 10-position screw-terminal connector provides user-defined external connections, and a general-purpose prototyping area in the center of the board accepts user components, for example, OR'ing diodes to combine multiple diagnostic alarm signals into a single output.
