Elmo PSS User Guide Installation 3-2 MAN-PSSUG (Ver. 3.01) The AC power supply can be of any voltage in the range defined in the technical specifications (section 2.4). It must be able to deliver power to the amplifiers (including peak power), without significant drops. A three-phase supply is always recommended whenever possible, in order to provide better DC bus voltage stability (low voltage ripple) under high load conditions. The recommended AC voltage is: 1.2 x VAC (min) < VAC <

Elmo PSS User Guide Installation 3-4 MAN-PSSUG (Ver. 3.01) 3.3.2 Capacitor Reforming All PSS power supplies undergo capacitor reforming prior to shipment to the customer. However, if the power supply has been idle (at the customer site) for a period of nine months or more, the capacitors must be reformed before startup. To perform capacitor reforming: 1. Connect a 25-VAC supply at the AC input terminals and a 100-W/220-V (or 50W/110-VAC) light bulb at the power output terminals. 2.
