当使用两个电源时,模块化电源系统II可以分成两个部分,每个部分有四个电源模块槽位。这种2N分割架构提供了高水平的电源可用性。在正常情况下,每个部分仅提供50%的负载,但在故障条件下能够提供100%的负载。50%的低应力保证了较长的使用寿命。
Configuration:
• Input Power: 120/240 VAC, 125 VDC
• Output Power: 5, 15, -15, and 25.5 VDC
Part Numbers: IPSYS01, 6641139G1, 6641138F1
Features:
Supplies Operating Voltages to Both Harmony Block and Rack Equipment
Selectable N, N+1, N+x, and 2N Power Supply Redundancy
260 Watts Output Per Module
The ABB Harmony Modular Power System II is designed to be flexible so that it can be easily adapted to the needs of the application.
When two power sources are utilized the Modular Power System II can be split into two sections with four power module slots per section. This 2N split architecture offers the highest level of power availability. Each section supplies only 50 percent of the load under normal conditions but is capable of supplying 100 percent of the load under a failure condition. The low stress at 50 percent of capacity assures a long lifetime..
