The Topaz S4 N+1 scalable DC to AC inverter is used by most large telecom providers as well as anyone looking for the highest grade of critical AC power from a DC power plant.

Scalable 3.5 kVA power modules can be added in a N+1 redundant
configuration up to 21 kVA making the S4 ideal to deal with future power requirements.

S4 inverter modules are packaged into a “hot swap” receiver cabinet that allows anyone to safely replace or add modules without interruption to the critical load.

Available as a complete power system, the S4 can be packaged with AC distribution and external maintenance bypass in an open frame relay rack.
