In daily life and various professional scenarios, apart from power strips and PDUs (Power Distribution Units), do you know other types of socket devices? Do you know what type of socket is required to power a professional power equipment management system? This article will introduce a socket that can connect and control multiple professional devices – the power supply sequencer!
Difference Between Power Strips/PDU and Power Supply Sequencer
First, in the field of electrical device connection and management, power strips, PDUs, and power supply sequencer is often confused. However, there are significant differences between them. Let's break down how they differ from the power supply sequencer.
Power Strip: Entry-Level Power Expansion
The power strip is one of the most familiar electrical distribution tools. Its main function is simply to expand the number of sockets, serving as a basic power interface extension.
Primary Function: It can connect one or more electrical devices, with a limited power load, and meets the needs of households or small offices where multiple devices are used simultaneously.
PDU: Intelligent Power Distribution
A PDU is mainly used for electrical equipment installed in rack-mounted systems. It provides overcurrent protection and a main control switch, with optional features such as lightning protection and surge protection.
Primary Function: PDUs typically have larger wire specifications and can handle higher currents, making them suitable for factories, data centers, schools, and similar environments.
Power Supply Sequencer: Precise Control for Professional Scenarios
A power supply sequencer is designed to control the power-on and power-off sequence of multiple electrical devices precisely. It effectively prevents equipment from being damaged by sudden current surges, voltage fluctuations, and other issues, thus greatly extending the lifespan of the devices.
Primary Function: It provides orderly power control to protect devices, simplifies operational processes, enhances work efficiency, and ensures the stable operation of the power supply system. It is particularly suited for professional scenarios where the startup sequence of devices is strictly required.
Delving Deeper into the Appeal of the Power Supply Sequencer
Power sockets come in various specifications, commonly 10A, 16A, 20A, 25A, and 32A, among others. Most power supply sequencers have output sockets rated at 10A. To ensure the 10A current output and prevent issues like electric leakage or short circuits, what measures are taken inside the power supply sequencer?
Take an 8-way power supply sequencer as an example:
Output: 8-way sequenced control output with single-phase three-wire 10A universal sockets.
Includes a 16A relay to ensure that the rated current of 10A flows smoothly.
Uses numerous 1.5mm pure copper cross-wires to ensure stable and reliable operation when high currents are in use.
Configured with 13A purple copper universal sockets, suitable for various plug types. The purple copper has a high copper content, providing excellent conductivity, thermal conductivity, ductility, and corrosion resistance.
Insulation paper is used to prevent leakage, and sufficient space is left between the relay board and the socket. The central terminals are specially lengthened for overcurrent and short-circuit protection.
With the advancement of technology and the widespread application of electrical equipment, when selecting power management equipment, users should choose the solution that best suits their needs. For users running multiple devices simultaneously, requiring precise control over the device startup sequence, and aiming to prevent current damage to equipment while ensuring stable operation, the power supply sequencer is an indispensable professional tool.
