• AC/DC Disconnect Panels 

Dedicated AC and DC circuit breakers protect the individual power supplies and provide for individual control/shutdown/replacement of any power supply without disrupting operation.

• Cooling System 

Each supply has separate fans, and rack blowers bring cool, filtered air in at bottom and exhaust heat out upper vents. The system is thermostatically controlled and monitored to sense any malfunctions.
