- DK PDU metered, compact basic power distribution incl. energy measurement per phase, with network interface and display, WLD: 44x1695x70 mm, IEC 60 320: 24x C13, 6x C19
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 with 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 metered has extensive measurement functions
for the current and power monitoring of each phase. The
integral TFT colour display anables the basic
configuration setting and quick access of the
electrical consumption data. Two Gigabit network
interfaces and the integrated Web server allow 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.
The PDU has a AC/DC sensitive
residual current monitoring (RCM Typ B).
Residual current in measured per circuit-breaker.
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.
This changes the PDU length.
The warranty for proper operation is 24 months.
