and resilience), physical Capacity and cooling Efficiency - (ACE). It presents a new way of assessing, balancing and visualising these critical indicators of data centre performance. ACE Performance Score works by mapping data
Future Facilities, a provider of predictive modelling for data centres, has introduced its ACE Performance Score - a tool that enables data centre owner/operators to accurately track and improve the performance of their data centres, to avoid costly overspend. Critically, it allows them to track performance in
a sustainable and repeatable way, meaning that they can exercise much greater control over increases in down-time, cost per kW of IT load and total cost of ownership. The score is derived from the three
interconnected variables that ultimately determine how costly a data centre is - Availability (up-time

Wieland Electric has increased its range of standstill monitors with the addition of the SVM 4001K, a new device that has been designed to monitor AC drives
without the need for
additional sensors. Standstill detection is achieved by the evaluation of the induced residual voltage during the run down of single or 3-phase AC motors. The SVM 4001K is connected directly
to the supply voltage connections of the monitored AC motor and, when the motor is switched off, should the voltage at terminals L1, L2 and L3 of the device exceed the pre-set threshold voltage, the relay contacts will open instantaneously. When the monitored voltage falls
below the set threshold voltage during the run down of the motor, the output relay will be turned on after an adjustable delay of up to 20 seconds. The SVM 4001K provides safe
control of guards and interlocks and has adjustable threshold voltage and ‘on-delay’ times. The device operates with a supply voltage of up to 690V AC and relay outputs of 230V AC/ 8A. The new SVM 4001K standstill
monitor is part of Wieland’s range of safety products.

Meeting the requirements of the white goods market while also being well suited for smart meters and smart sockets, Panasonic’s new DW-H relay switches power surges of up to 100A for a period of 5ms reliably and nominal switching capacities of up to 16A/277V AC. Its compact design and low coil power dissipation
of 200mW for the one coil latching type or 400mW for the two coil latching type, make this relay well suited for the white goods market. Advantageous when designing the relay in an application are its

6mm creepage and clearance distance between contact and coil and its breakdown voltage of 5kV between contact and coil. The surge withstand voltage here is 12kV. For this market segment, the DW-H relay is available
in an LCP housing (for reflow soldering) and also, upon request, in PBT, which fulfills the VDE standard EN 60335 (glow wire test, creepage resistance).

(for example, inventory and ‘real time’ power) from DCIM tool sets into a powerful 3D virtual facility model. With that automated process accomplished, it then simulates the resulting distribution of airflow and temperature in the space. This confluence of predictive modelling and DCIM data is called Predictive Modelling for DCIM. The ACE Performance Score plots the data centre’s
Performance Gap - the difference between maximum design potential and what can be achieved in day to day data centre operations. Once the performance gap has been identified, data centre professionals can make informed decisions about which variables to protect, which to sacrifice, where to save money, how to lessen the impact of change and how to ensure data centre investments are maximised.

Enter 228 SAFE AS HOUSINGS
Rittal is offering its housings with a protection category of IP65, which provides device shielding from exposure to dust and water jets They are designed to accommodate
TFT screens up to 24" (measured along the diagonal) in the 16:9 and 16:10 widescreen formats. A full width viewing window made from a single pane of safety glass maximises the display area and a combination of rounded edges and aluminium grips prevent injury. Housings containing TFT screens can
be mounted quickly and efficiently thanks to a holder with the VESA 75/100 mounting hole pattern. A hinged door on the back of the housing provides easy access to the device. Manufactured from sheet steel, Rittal’s housing measures 650 x 450 x155mm.

Enter 229 PRESSURE SWITCH FOR FAN AND FILTER STATUS
Sontay has introduced the new PA-DPS-W air differential pressure switch to its product family. The PA-DPS-W switch includes IP65 protection without the need for an additional outer box. Providing reliable switching for filter or air flow monitoring, the PA-
DPS-W is an easy to install solution as only one screw is required for the housing cover and each unit includes a duct fixing kit, enabling faster installation. These sensitive switches are suitable for providing an indication of fan status and dirty filter conditions. The PA-DPS-W has a scale in Pascal’s force per unit area, for easy
measurement. Each PA-DPS-W is individually laser etched for high accuracy switch setting and the switching set-point is adjusted by means of a knob mounted under the main cover.
