Open and enclosed power supplies
To ensure reliable operation of Rosahl membrane dehumidifiers under all operating conditions it is important to use a switching power supply (PSU) with the performance specified in the relevant membrane specification sheet.
Service life and reliability of the power supply are affected by the ambient temperature. Depending on the ambient temperature of the power supply installation and the supply voltage used, the PSU may require derating. (Please refer to the specification)
Westside offers a range of CE and UL marked PSUs in open and semi-enclosed construction. Go here for the catalogue page
Open construction: Otherwise known as an open board type PSU has an IP00 rating. The open board PSU has four mounting points on the circuit board.
When using mounting posts to install the open board switching power supply, ensure the posts do not exceed the 8mm hatched area indicated in the installation information. Allow minimum 8mm clearance from the mounting surface.
Model BWT3.3SX-U1A for size 7 membranes
Model BWT3.3SX-P-U1A for size 7 membranes
Semi-enclosed: The semi-enclosed version is also IP00, but with cover plates to provide additional mechanical protection and simpler installation.
The enclosed PSU has four tapped mounting points in the base and two along one side. Use all mounting points and do not over tighten fixings. The semi-enclosed PSU is not suitable for mounding on the underside of the mounting plate
