A purpose-built rack power outlet is usually called a PDU. PDUs typically use a modular structure to guarantee power to critical equipment such as communications gear in the rack, avoiding damage from high voltage or lightning induction. Small as it is, a PDU is one of the longest-working devices of all: as long as any equipment is running, the PDU is running. A poor-quality PDU can cause outages or even fire. Choosing a high-quality, high-performance power distribution unit for your network rack therefore ensures the operating safety of the whole system.
What advantages does a PDU have over an ordinary power strip? Here are the PDU features ordinary strips do not offer:
1. Lightning and surge protection: withstands impulse currents above 20KA; clamping voltage ≤ 500V.
2. Alarm protection: LED digital current display, full-course current monitoring, with alarm function.
3. Filtering protection: fine filtering delivers ultra-stable, clean power output.
4. Overload protection: effectively prevents problems caused by overloading.
5. Misoperation prevention: the PDU master ON/OFF switch has a protective cover against accidental shutdown, with optional dual feeds.
6. Modular design: international-standard, British, German, American and other outlet modules can be freely interchanged to meet the different needs of multinational customers.
