1 year warranty

SSA offers two separately ordered AC power supply models:

Stainless steel -AC-PS-625W
SSA-AC-PS-1000W
The SSA AC power supply automatically adjusts to the input voltage and frequency, allowing an input voltage of 100 to 240 VAC and a frequency of 50 to 60 Hz. View the specifications in Operation SSA Specifications. No additional adjustments are necessary. For North American installations, a 15 amp power cord is required. For more details, see Start SSA.

You can install up to two power supplies in the rear of the SSA chassis. Supports two power supply redundancy modes:

Redundancy mode, in which the power supplied to the system is equal to the maximum output of the lowest rated power supply. If you choose to use two power supplies in a redundant power supply configuration, you can guarantee system power redundancy if one power supply is lost. In this mode of operation, the power supply is hot swappable.
Non-redundant or additive mode, where a combined output of two power supplies is available for system use. If you choose to use two power supplies in a non-redundant power supply configuration, the loss of a single power supply may result in a system reset. In this mode, the power supply is not hot swappable.
The following power configurations are supported:

redundant
625 Watts (2 x 625)
625 Watts (625 + 1000)
1000 Watts (2 x 1000)
Non-redundant (Additive)
625 Watts (1 x 625)
1000 watts (1 x 1000)
1250 watts (2 x 625)
1625 watts (1000 + 625)
2000 Watts (2 x 1000)
