Voltage:
• Nominal STS input voltage ratings are 600VAC, 480VAC, 400VAC, 240VAC, 208VAC, LL RMS 3- phase, (3)
wires + ground.
• Voltage Range: +/-10% of nominal
• Source Voltage Distortion: Up to 15% THD plus notches, flat topping, and/or ringing transients
• The STS output voltage is the same as the input voltage.
• Frequency: (60) Hz. +/-0.5 Hz; (50) Hz +/-0.5Hz
Current:
• The STS continuous current rating is 2000A input and output.
• If the STS output is to a PDU, the STS continuous current rating must match or exceed the PDU input
rating.

The STS will safely withstand without mis-operation or damage:
• Transient voltage surges on either AC power input as defined by ANSI/IEEE C62.41 for Category B3
locations (high surge exposure industrial and commercial facilities)
• Electrostatic discharges (ESD) up to 10 kV at any point on the exterior of the unit
• Electromagnetic fields from portable transmitters within 3 feet (1 meter) of the unit
Grounding for the WaveStar Static Transfer Switch must comply with local building codes and National Electric
Codes.
