Nowadays, rack power distribution units are made to deliver power to networking equipment housed in racks or cabinets while also offering electrical protection.Rack PDU  performance options change along with data centers' needs and specifications. The following list will point you on the right path and ensure that the PDUs you select will work with your data center's current and future designs. 

1. Type of mount: 

A rack PDU can be put either horizontally or vertically, depending on where you wish to place it. A PDU can be mounted vertically on the back or side of the enclosure or installed horizontally inside the rack. Power cords can be installed on PDUs such that they come out of the section at either the top or bottom. 

2. Amperage: 

You will require a certain amount of amperage based on your power rating, which is the maximum sustained power draw a PDU can manage. Because a PDU with a 30A fuse will blow if a 30A circuit is exposed to more power than 30A for an extended period. 

3. Voltage: 

208/240V is the most typical voltage output for computing equipment, with a new trend toward 400V input. There are several input voltage possibilities for rack PDUs and various amperages. Rack power distribution unitrequirements can be determined by verifying the infrastructure voltage. 

4. Single or three-phase power: 

Whether you require a single-phase PDU or a 3-phase PDU depends on the type of power distribution used in your data center. Where the phase is divided up in the distribution system is where the difference lies. When it malfunctions at the distribution panel, power to the rack will only be provided in one phase. 

5. Local meters: 

PDUs with a local meter display are rack PDUs of standard quality. They show when circuits are getting close to their capacity and breakers might trip. Knowing how much amperage is being drawn from the PDU allows you to make decisions and keep an eye out for any issues. 

6. Plug kind: 

On rack PDUs, NEMA-style plugs are the most prevalent. Locking plugs are widely used to protect electrical connections and stop unintentional disconnections. 

7. Size of the power cord: 

Standard power cord lengths can frequently be customized, depending on the manufacturer. For instance, the standard from most manufacturers is 10 feet, but they have designed rack PDUs with power cords up to 40 feet or longer. 

8. Remote observation: 

A device with remote monitoring capabilities can be what you need if you want to know more than just the amperage being drawn from your PDU. This may allow granular power usage effectiveness reporting, depending on your choices. The monitoring system can even provide alarms when the PDU is operating improperly. 

9. Receptacle type and number: 

The number of outlets you require should consider future rack expansion and the number of devices that can be plugged in. Vertically mounted PDUs often offer more outlets per unit since they can be longer. Determining the types of plugs utilized on your rack equipment is also crucial. 

10. Using a remote switch: 

Some rack PDUs can remotely switch outlets on and off if that feature is vital to you. The ability to remotely turn on and off individual outlets and manage equipment reboots gives data center operators improved control.
