Does a 3000 W AC&high-voltage DC power module support AC power input on CE12800 series switches

0

A 3000 W AC&high-voltage DC power module supports 220 V/110 V AC power input and 240 V DC input, and provides 53.5 V DC/3000 W output.

Description:
When AC power supply is used and the input voltage is lower than or equal to 175 V AC, the rated output power reduces to 1500 W.

Do CE series switches support high-voltage DC power supply
China's national standard for high-voltage DC power supply was released in December 2011 and took effect in February 2012. The standard defines power supply with 240 V DC (192 V to 288 V). The International Electrotechnical Commission (IEC) released the 380 V DC (260 V to 400 V) power supply standard, ETSI EN 300 132-3-1 V2.1.1, in February 2012. Because the two standards were released not long ago and define different voltage ranges, power supply manufacturers have not released power supply products complying with the high-voltage DC power supply standards. All the manufacturers use AC power modules in 240 V DC power supply scenarios. AC chassis modules on CE series switches can work in a certain high-voltage DC voltage range. For security purpose, power modules of the switches provide overvoltage protection function and will cut off power supply when the input voltage exceeds the upper limit. The voltage protection function prevents damage to power modules or other dangers caused by abnormal input voltage. The voltage upper limit triggering overvoltage protection is larger than the maximum input voltage allowed by a power module. The 240 V DC input standard has higher requirements for power module protection components and secure distance than the 220 V AC input standard. Currently, AC power modules can work with 240 V DC power input.

Requirement for using 2200 W AC power modules
Requirements for using 2200 W AC power modules are as follows: - Select the power cables with the maximum current of greater than or equal to 16 A. - If country-specific power cables are required, ensure that the power cables used on a device comply with standards of the destination country or region. - Electronic and electrical cables cannot be used outdoors.

Do S series switches support AC and DC power modules simultaneously
Fixed switches: - In versions earlier than V100R006C01, the S2700, S3700, and S5700 cannot use AC and DC power modules simultaneously. - In V100R006C01 and later versions, the S3700-26C-HI, S5700-28C-HI, and S5700-28C-HI-24S can use AC and DC power modules simultaneously. - In V200R001C00 and later versions, the S5710-28C-EI and S5710-52C-EI can use AC and DC power modules simultaneously. - In versions earlier than V200R005C00, the S6700 cannot use AC and DC power modules simultaneously. - In V200R005C00, the S5700-EI (non-PoE), S5700-SI (non-PoE), and S6700 can use AC and DC power modules simultaneously. - In V200R006C00 and later versions, the S5720-HI (non-PoE) can use AC and DC power modules simultaneously. - In V200R007C00 and later versions, the S5720-C-EI (non-PoE) and S5720-PC-EI (non-PoE) can use AC and DC power modules simultaneously. - In V200R008C00 and later versions, the S5720-SI (non-PoE), S6720-EI, and S6720S-EI can use AC and DC power modules simultaneously. S7700 and 9300:

When a switch is running a version earlier than V200R010C00, it does not allow mixing of AC and DC power modules or power modules of different power values in the same type of power slots (system or PoE power slots).

  • When a switch is running V200R010C00 or a later version, it allows mixing of AC and DC power modules in its system power slots.
    • Two 800 W AC power modules and one 1600 W DC power module are interchangeable in different power supply areas, that is, two 800 W AC power modules in area A (or B) and one 1600 W DC power module in area B (or A).
    • Mixing of 2200 W AC and DC power modules are supported.
  • S9700 and S12700�?When a switch is running a version earlier than V200R010C00, it does not allow mixing of AC and DC power modules or power modules of different power values. When a switch is running V200R010C00 or a later version, it allows mixing of 2200 W AC and DC power modules.
