Rittal PDU managed Model No.: DK 7979.439
Compact power distributor for deployment in IT server
and network enclosures. Vertical installation in the
Zero-U space using the supplied universal brackets for
common IT racks. Suitable for tool-free quick assembly
in the Rittal VX IT and TS IT racks using the special
supplied plug-%-play fastener. Robust aluminium housing
with permanently mounted output slots, IEC 60320/C13 or
IEC 60320/C19 as well as CEE 7/3 (earthing-pin) and
BS 1363 (UK), depending on the type
(see below for details). The IEC C13 / C19
output slots can be protected with a lock against
unintentional removal of the connectors. Unused slots
can be closed wicht slot covers available as
accessories.This precludes an unintentional overloading
of individual phases an circuits. The fuse circuits and
phases are colour-coded for multiphase PDU variants.
A fixed-mounted connection cable with IEC C20 or CEE
connector appropriate for the variant makes the PDU
available for immediate deployment.
The PDU managed has extensive measurement and switching
functions for the current and power monitoring of each
output slot. The integral TFT colour display enables
the basic configuration setting and quick access to
the electrical consumption data. Two Gigabit network
interfaces and the integrated Web server allow remote
access and data transmission using various protocols.
The consumption parameters can be forwarded to a DCIM
software via SNMP, OPC-UA, Modbus/TCP. For monitoring
the ambient parameters, up to 16 sensors (for example
temperature / humidity / smoke / leakage / access)
as well as VX IT and TS IT handle systems from the CMC
accessories program can be connected to the CAN sensor
interface.
Optinally, an overvoltage protection module (type3) can
be placed on the PDU at the infeed; the overvoltage
protection module is equipped with arrestors that can
be replaced during operation. For intelligent PDUs, the
status is monitored via the network interface, the PDU
basic has a floating alarm contact for monitoring the
overvoltage protection. As option, intelligent PDU
variants can be supplied with an AC/DC sensitive
residual current measurement (RCM type B) with up to 6
measurement points. This changes the PDU length and the
number of installed slots for each standard length.
The warranty for proper operation is 24 months.
