Page 112 ReFlex Power™ AC Power Supplies OLTAGE For applications where regulation is important, the contribution of the load wiring to voltage drop from the output terminals of the AC module to the load must be considered. The wire gauge must be selected to maintain an acceptable total voltage drop for the load wiring under the maximum current.
Page 113: Operation
AC Power Supplies ReFlex Power™ Twisting the load wires provides an additional benefit in reducing the parasitic inductance of the cable. This improves the dynamic response characteristics at the load by maintaining a low source impedance at high frequencies. Also, with long load wires, the resultant inductance and resistance could produce high frequency voltage fluctuations at the load because of current variations in the load itself.

Page 115: Modes Of Operation
AC Power Supplies ReFlex Power™ 4.5.2 ODES OF PERATION The AC power supply module is capable of operating in either standalone or in groupings of parallel, and multi-phase output configurations. This allows extending the power, voltage, and current ratings while minimizing the number of unique modules comprising a system.
Page 116: Figure 4 9. Cv And Cc Regulation
ReFlex Power™ AC Power Supplies through software. In a multi-phase group the load could be connected in wye or delta configuration, but the module outputs must be wye connected. CAUTION Do not connect the AC modules in a delta configuration. Modules must be set to the same output range when multi-phase connected.
Page 117: Load Connection Configurations
AC Power Supplies ReFlex Power™ ONSTANT OLTAGE The AC power supply will operate in constant–voltage regulation whenever the load current is less than the programmed current setting. In this mode, the power supply maintains the output voltage precisely regulated to the programmed voltage setting while the load current varies with the load requirements.
Page 118: Figure 4 10. Standalone Output Configuration
ReFlex Power™ AC Power Supplies TANDALONE ONFIGURATION Single loads are connected directly to the front panel output terminals, and the AC power supply module is configured to operate in the standalone mode. Twist the load wires or maintain them closely in parallel for their entire length to minimize parasitic inductance and coupling from external circuits.
Page 119 AC Power Supplies ReFlex Power™ The paralleled modules are programmed as a single, virtual channel with a current rating equal to the sum of the number of modules connected in parallel. The master and slave supplies will share the output current equally. Fault shutdown is coordinated across all modules: a fault within any module of the group will result in shutdown of all modules.

Page 248 ReFlex Power™ DC Power Supplies OLTAGE For applications where regulation is important, the contribution of the load wiring to voltage drop from the output terminals of the DC modules to the load must be considered. The wire gauge must be selected to maintain an acceptable total voltage drop for the load wiring under the maximum peak current.
Page 249: Operation
DC Power Supplies ReFlex Power™ Twisting the load wires provides an additional benefit in reducing the parasitic inductance of the cable. This improves the dynamic response characteristics at the load by maintaining a low source impedance at high frequencies. Also, with long load wires, the resultant inductance and resistance could produce high frequency voltage fluctuations at the load because of current variations in the load itself.

Standalone Output Configuration ARALLEL ONFIGURATION DC power supply modules of the same model can be connected in parallel. The paralleled supplies operate in a master/slave configuration, where the master controls the output voltage and total current, and provides control signals through the Mainframe backplane to the slaves to set their output current.
