Control and protection of AV and IT equipment with switchable AC/DC PDU

The new Power Distribution Unit (PDU) from GUDE allows control, energy measurement and monitoring of up to 21 connected devices with AC and DC voltage.

With Expert Power Control 8291-1 GUDE Systems GmbH presents a power distribution system that is used in professional installations with direct current (DC) voltage requirements. The switchable LAN socket allows the connection of up to 21 AV and IT devices. Four different voltages can be operated: 17 switchable load outlets with DC voltages of 24 V, 12 V and 5 V and 4 switchable load outlets of 230 V (AC.) Due to the different connections on the back of the device (IEC C13, terminal clamp and USB type A) and the different supply voltages, a large number of AV and IT devices can be connected. The integrated industrial power supply makes the often unreliable plug-in power supplies of the end devices superfluous. Thanks to its compact design in a stable metal housing, the PDU occupies only one height unit in 19-inch cabinets.

Once in operation, IT users benefit from the following advantages with the AC/DC power distributor. Please click the title for more information:

Power-cycling (reboot) of connected devices helps applications to get back on their feet when they have hung up: Either automatically via watchdog monitoring or by remote access via the integrated web application. In addition, power and residual current monitoring prevents critical system states in the installation.

Short-circuit fuses per output (eFuse) prevent damage to other loads. In addition, an integrated type 3 surge protection ensures greater operational safety.

The integrated energy meters offer precise measurement of power consumption and enable the exploitation of energy saving potentials.

The IP power distributor occupies only 1 height unit in the rack and allows the direct connection of many IT and AV devices thanks to the integrated power supply unit. The space-consuming plug-in power supply units of the individual end devices can be dispensed.

Monitoring of temperature, humidity and air pressure in the installation environment through additional cable sensors. This allows critical conditions to be avoided in advance through preventive measures.

GUDE Systems – PDU virranjakeluyksiköt

PDU (virranjakeluyksikkö) on periaatteessa jatkojohto, joka asennetaan ennen kaikkea 19 tuuman palvelinkaappeihin joko vaaka- tai pystysuunnassa. Nämä kaapit ovat usein palvelinkokoja, joita käytetään palvelinkeskuksissa ja palvelintiloissa. PDU jakaa virran eri laitteille, kuten palvelimille ja kytkimille. Erilaiset laiteliitännät ovat mahdollisia, joista yleisimmät ovat IEC C13, IEC C19 ja turvapistorasiat.

PDU-laitteita on periaatteessa kahta tyyppiä:

✔ Passiivinen PDU: Se on yksinkertainen jatkojohto, joka vain jakaa virtaa.

✔ Aktiivinen PDU: Tehonjaon lisäksi aktiivisella PDU:lla on lisätoimintoja. Sitä voidaan valvoa ja ohjata dataliitännän kautta. Siten aktiivinen PDU kommunikoi LAN-liitännänsä käyttäen TCP/IP:tä sekä protokollia kuten SNMP, Modbus ja HTTP/HTTPS. Tällä tavalla PDU mahdollistaa etäohjauksen ja integroinnin valvontaohjelmistoihin.

Lisäksi PDU-laitteeseen voidaan liittää erilaisia antureita mittaamaan esimerkiksi laitetilan lämpötilaa ja kosteutta. Määrittämällä antureille kynnysarvot ja jos joku tallennetuista kynnysarvoista ylitetään, aktiivinen PDU-laite lähettää hälytyksen välittömästi sähköpostitse halutuille henkilöille.

Aktiivisten PDU:iden sisällä voidaan lisäksi tehdä ero kytkettävien ja mittarillisten virranjakeluyksiköiden välillä. Näitä PDU-laitteita kutsutaan usein myös älykkäiksi virtalähteiksi.
