1. PDU profiles

 

In order to save costs, ordinary PDUs will choose low-cost plastics as profiles; cost-effective PDUs will choose aluminum alloy profiles. Compared with plastic profiles, aluminum alloy profiles have the advantages of high strength, good heat dissipation, good fire resistance, and anti-static.

 

2. Conductive materials inside the PDU

 

 

The internal material of ordinary PDU is single-strand copper wire, and the wiring is easy to loosen, short-circuit, desolder, etc.; the cost-effective PDU uses copper bars to run through the integrated welding process, there is no hidden danger of desoldering and loosening, and the conductivity is high.

 

3. Maximum load current of PDU

 

The maximum load current of an ordinary PDU is the sum of the total power of all devices in the cabinet, and the maximum load current is calculated; the maximum load current of a cost-effective PDU is the sum of the total power of all devices in the cabinet plus 20% as redundancy to calculate the maximum load current. load current.

 

4. The number of output bits of the PDU (the number of sockets)

 

The number of digits of ordinary PDUs is determined according to the number of servers; for cost-effective PDUs, the number of output digits is determined according to the number and format of servers, and two more jacks are reserved for redundant configuration or maintenance testing. use.

 

5. The brand of PDU

 

International brands: complete parts certification, quality assurance; but high price, long lead time, generally takes 6-8 weeks, single-bit type, poor compatibility with equipment plugs, is a standard model product, can not be customized.

 

Domestic high-end brands (high cost performance): complete parts certification, complete factory qualifications, factory inspection of single products one by one, high cost performance, complete service, and high degree of product customization.

 

Domestic low-end brands: parts certification is incomplete, product stability is not high, it is possible to piece together products, without qualifications or under the guise of others, and the price is extremely low.
