Kell Systems Soundproof Cabinets (PSEs) enable deployment of servers and network hardware directly in the office workspace, doing away with the need for dedicated computer rooms.
They combine extreme noise reduction and very high thermal capacity with exceptional reliability and a truly all-inclusive, plug-and-play specification. A host of unique, installer-friendly features ensure quick and easy systems deployment and the PSE’s office-quality appearance blends seamlessly into almost any office environment.
Please note that standard Kell Systems PSEs as shown herein are not suitable for use with blade servers. Please contact your Kell representative about alternative Kell solutions for deployment of these types of devices.
External dimensions:
Height 750 mm / 29.5" x Width 750 mm / 29.5" x Depth 1115 mm / 43.8"
Weight:
119 kg / 262 lbs
Physical rack capacity:
12 x EIA 1¾" / 44.5 mm rack spaces
4-post rack, fully EIA-compliant, with fixed rear posts and adjustable front posts
Rack depth 800 mm / 31.5", adjustable down to 720 mm / 28.3"
(option for baying kit to link cabinets together, part code BK12)
Extra internal cabinet depth:
Forward of the front rack posts: 100 mm / 4" space for front frame cabling/patching
Rearward of the rear rack posts: 60 mm / 2" except where fan modules intrude
Floor space requirements:
Individual cabinets are designed to be pushed back flush against a wall. An air space of 200 mm / 8" on both sides of the cabinet is essential for normal operation.
Baying cabinets together:
Baying kit option available. The easy-to-fit baying kit maintains the soundproof seal but opens adjacent cabinets onto each other internally.
Special notes on baying:
1: Unlike single cabinets, bayed cabinets cannot be pushed fully back against a wall. Air space of 100 mm / 6" behind the cabinet is essential for normal operation.
2: Baying PSE12 cabinets together reduces the maximum recommended thermal load in each cabinet from 1.2 kW to 1 kW.
3: In bayed PSE cabinets, it is essential that the thermal load is distributed evenly between the cabinets.
Cooling system:
1 x Kell Systems ultra-low-noise exhaust fan module
1.2 kW maximum recommended total thermal load inside the cabinet
Power consumption:
19 Watts total power consumption by the PSE12 itself, including cooling system
Noise of PSE itself:
40.5 dBA total noise generated by PSE, measured 1.0 m / 39" in front of the cabinet
Noise reduction:
18.5 dB broadband noise reduction, measured 1.0 m / 39" in front of the cabinet
(HP and Dell servers used as noise source in noise reduction measurements)
Mobility:
4 x heavy duty castor-type wheels
Front wheels have 360° rotation for steerability
Rear wheels have fixed front-to-back motion for stability
Rear and side access:
Detachable rear side panels, left and right, for installation and maintenance access
Detachable rear fan module backplane gives completely open rear rack access
Cable management:
100 mm / 4" width full-height vertical cable trays to each side of front of rack
100 mm / 4" width full-height vertical cable trays to each side of middle of rack
100 mm / 4" width full-height vertical cable trays to each side of rear of rack
Option for heavy duty cable management ladders to front of rack for larger scale network cabling applications, part code VCM12
Dust filtering:
Optional air intake dust filters, part code DF12
Internal power distribution:
All power outlets in Kell Systems PSEs feature surge protection
UK & Europe: 7 x IEC 320 C13 (10 A / 220/240 V) sockets, arranged vertically
USA/Canada: 7 x US 3 pin sockets, arranged vertically
Rest of world: 7 x IEC 320 C13, arranged vertically, unless specified otherwise
PSE power input connection:
All Kell PSEs have power input via an IEC 320 C14 (male) trailing lead for connection to an in-rack UPS, and an extension cable for connection to a wall outlet. User may choose the preferred way to connect. The extension cables are configured as follows:
UK: IEC C13 female trailing socket to standard UK 3-pin plug
Europe: IEC C13 female trailing socket to Schuko 3-pin plug
USA/Canada: IEC C13 female trailing socket to standard US 3-pin plug
Custom: IEC C13 female trailing socket to any user-specified 3-pin plug
Grounding/Earthing:
All equipment installed within a Kell Systems PSE should have conventional grounding/earthing via power cables, but unlike conventional metal-case cabinets, the PSE itself has no requirement for additional grounding/earthing in the form of ground strapping or pipe earthing etc. The cabinet shell is constructed entirely from non-conductive materials and the rack is completely isolated from outside contact.
Anti-static measures:
No anti-static measures are required in a Kell Systems PSE installation. The rack has full electrical isolation and is not susceptible to static build up that can originate in conventional metal racks by contact with artificial carpet or other flooring materials.
Door locking:
Key operated lock
Option for high security code-entry lock, part code CEL1
Standards compliance:
Electrical systems meet or exceed BS EN 60950:2000, BS 5733:1995 and ISO 9001- 2000 and are compliant ROHS Directive 2002/95 and UL60950-1 (USA).
Electronic subsystems meet or exceed EN 60950-1:2006 ‘Information Technology Equipment – Safety, Part1: General Requirements’ and EN292: Part 1: 1991 ‘Safety of machinery -basic concepts, general principles for design’. Electronics subsystems are CE- certified, certificate number FTE4412GFM-M00 CE, and are compliant with harmonised international standards IEC60950-1:2001 and UL60950-1 (USA).
Acoustic foams meet or exceed UL94-HF1 'Standard for Tests for Flammability of Plastic Materials for Parts in Devices and Appliances‘, (USA) and acoustic barrier materials meet UL94-V0 (USA). Multi-layer composite acoustic materials meet UL94- V0 (USA) and UL94-V2 (USA). Flammability ratings meet or exceed requirements in BS 60950-1:2002 'Information Technology Equipment - Safety' and harmonized international equivalent standards EN60950-1:2001 and IEC60950-1:2001.
