Simplex Neptune Trailer Load Bank (400-650kW)

The Simplex Neptune Trailer-Mounted Load Bank is designed for high capacity load testing of generators, periodic reliability exercise of standby generators, regenerative power absorption of inertial motors with reverse power protection of generators, and other load bank applications. Available with or without trailer.

FEATURES

• Load Capacity Options: Max capacity up to 400, 450, 500, 600, or 650kW.
• Common Voltage Options: Single voltage 208 or 480VAC. Dual Voltage 240/480V – derates at lower voltages. Other 50, 60, & 400Hz voltages up to 600V also available.
• Load Step Resolution: 5kW minimum.
• Duty Cycle: Rated for continuous operation.
