RPS9 Power Supply INTRODUCING THE RPS9 The RPS9 is a linear power supply which, like other linear supplies, produces DC voltages by rectifying, smoothing and regulating AC voltages from the secondary windings of a mains transformer. Allen & Heath mixing consoles employ a number of DC voltage supply levels in their operation and these are provided at the output of the power supply unit.
Installation of the RPS9 Free Standing The RPS9 can be operated as a free standing unit without requiring any special cooling arrangement, but should not be accidentally or deliberately covered in any way. Always stand the unit on a firm flat surface well away from any soft furnishings such as carpets or curtains. Rack Mounting The RPS9 is designed as a 19 inch rack mount unit and will occupy 2U (3.5 inches) of rack space.
THIS UNIT CONTAINS NO USER SERVICEABLE PARTS, REFER ALL SERVICING TO A QUALIFIED ENGINEER, THROUGH THE APPROPRIATE DEALER NETWORK Mains Voltage Setting SPECIAL ATTENTION SHOULD BE GIVEN TO THE FOLLOWING INFORMATION The RPS9 is capable of operating over a wide range of AC mains input voltages by means of a mains voltage selector. It is important to check that the RPS9 has the correct voltage setting as marked on the rear panel of the power supply.
Replacing Mains Fuse The AC mains fuse is located on the rear of the RPS9 unit next to the AC mains connector. In the event of a mains surge or underrated fuse value, the mains input fuse will rupture. Switch off the power supply and remove the mains lead plug from the “AC MAINS IN” socket on the rear of the unit. Check the fuse and replace if necessary. Check also the AC mains input voltage setting is correct for the mains supply in your area before switching the unit on again.
Servicing THIS UNIT CONTAINS NO USER SERVICEABLE PARTS. REFER ALL SERVICING TO A QUALIFIED SERVICE ENGINEER, THROUGH THE APPROPRIATE ALLEN & HEATH DEALER Initial operational tests on the power supply can be carried out by switching the unit ON and checking the front panel LED indicator is illuminated. If the LED indicator is not illuminated, check the fuses are intact in the mains plug (where fitted) and the unit fuseholder on the rear panel.
