- Article number:
- SK 3311.491
- Version
- LCU DX 3 kW redundant
- Benefits
- Space-saving solution by installing the redundant internal unit in the VX IT server enclosure or the Micro Data Center
- Maximum energy efficiency due to EC fan technology and IT-based control
- Control of the server inlet temperature
- The inverter-controlled compressor matches the cooling output to the current level of heat loss in the enclosure
- Absorbed thermal energy is emitted directly into the ambient air at the location of the (inverter controlled) external unit , without heating up the installation room
- Applications
- Cooling unit for VX IT server enclosures and for Micro Data Centers
- Function principle
- Within the internal unit, the redundant versions each have two cooling circuits and two controllers, plus two inverter-controlled external units. The fault and operating hours switchover mechanism ensures regular switching between the external units and a switchover in the event of a fault or a failure.
- The device supports "front to back" air routing typical of IT applications, and regulates the server inlet temperature to the set value
- Material
- Carbon steel, spray finished
- Color
- Internal unit: RAL 7035
External unit: white - Supply includes
- Internal unit (condenser)
2 external units (inverter controlled)
482.6 mm (19") mounting bracket cover with control and display elements
Condensate hose - Installation options in VX
- 19" profile rails, standard or dynamic, must be off-centered by 50 mm in regards to width
- The distance between the front of the 19" profile rails and the front edge of the VX frame must be at least 100 mm
- Two system chassis for the inner mounting level are required to fasten the internal unit
- Air baffle plates are required to separate the hot/cold zones within an enclosure
- A base/plinth is needed to route cables downwards
- Note
- If the cooling output falls below its minimum value, fluctuations in the air intake temperature may result
- The electrical connection is made to the external unit, the internal unit is supplied by the external unit
- A separate power supply is required for each external unit
