Economical Fast DC Power Supply, 5kW to 4MW
Economical Fast DC Power Supply, 5kW to 4MW
The AL3000 series are high-performance DC power supplies for production and R&D, from 5kW to 500kW (up to 4MW in parallel) at 10–1000V. Delivering clean, low-ripple output with fast response and over 92% efficiency. Flexible modes include CV, CC, CP, and internal resistance simulation, with CP models maximizing output at mid-voltage. AL3000R is available with regenerative power option.

DC Power Supplies with Fast Slew Rates
Using an isolation dual back-to-back full bridge topology, the AL3000 provides efficient and reliable solid state power conversion in non-regenerative mode.
The AL3000 is available in either standard version (max current available at max voltage) or in Constant Power version using a more flexible range where higher output current is available at lower voltage settings. This is illustrated in the diagram to the right.
Multi-turn potentiometers provide precision control over voltage and current set points. Settings can be locked so no accidental adjustment can be made.
Two large LED Segment displays provide continuous readouts of voltage and current to the load.
