Multi-SWITCH多路切换开关改善了供电的连续性。比单台UPS（在线式，具有手动旁路）或多台UPS 并联具有更高的可靠性。
运行原理
Multi-SWITCH多路切换开关可为多达8台的网络设备提供配电和远程管理，输入电源可以是两路市电，或两路UPS电源，或者两者结合。
Multi-SWITCH 可以将每个用电设备（多达8 台，每台最大电流要求不超过4A）连接到输入电源任何一路（A或B）。负载电流在LCD 上显示。
针对电源故障的保护
如果其一电源故障或者超出范围，Multi-SWITCH将切换负载连接到另一路电源上。（切换在瞬间完成，即使两路电源不同相）
针对负载故障的保护
如果其一负载设备发生故障（例如短路或超载），Multi-SWITCH 将切断此负载，以防止其他设备的中断。Multi-SWITCH 保护敏感型负载远离电源和硬件故障。
Technical specifications of the model
Operating principle
Multi Switch provides direct distribution of eight 10 A IEC outlets in a system with two input power lines (two mains inputs, or two UPS). Multi Switch is able to connect to either of the two input power lines, whilst simultaneously monitoring the power uptake.
Protection against load faults
If one of the loads fails (e.g. short circuit), Multi Switch disconnects the group of sockets where the load is connected, thus preventing other loads from being switched off (i.e. in the event of poor discrimination of the protection devices).
Protection against power supply faults
If one of the two power sources falls outside tolerance levels, Multi Switch will transfer the load to the second power source (switching is instantaneous if the two sources are in phase).
Multi Switch units switch power with no impact on IT equipment. Depending on the ITI Curve, typical power supplies will operate 20 msec. after AC voltage drops to zero.
The IEEE 1100-1999 standard also references the ITI curve. The SSI (Server System Infrastructure) standard recommends a hold-up time for power supplies to be a minimum of 21 msec. for a voltage range of 100-240 V.
Multi Switch units switch sources under these industry standard times. The switching time includes the time for the built-in intelligence to determine whether the voltage and frequency are in range. Any point of failure in the electronics does not cause a drop out of the output voltage because the unit incorporates redundancy of its electronic circuitry to avoid fault tolerance.
Features
- Full protection for loads against mains and load failures;
- Redundant power supply;
- Versatile to use: Multi Switch can be powered with 2 different power supplies (including 2 UPS of different sizes/types);
- 19” cabinet installation;
- LCD Display panel;
- Can be connected to PowerNetGuard supervision software;
- No signal connection between the Multi Switch and the power sources or loads is necessary;
- Slot for communications boards: the optional network card allows for remote in network connectivity, and management through HTTP, SNMP, and SSH protocol.
