Said to provide the highest rackmount density in the industry, The DLM 3 kW and 4 kW programmable dc power supplies can be stacked on top of one another without cooling space in between. Both units feature a 3,5" high (2U) chassis and have a 0.95 input power factor with a three-phase input and a 0.98 input power factor with a single-phase input.
Both the 3 kW and 4 kW models have output voltages from 0 to 5 Vdc to 0 to 600 Vdc and a current range from 0 to 5A to 0 to 450A. The output RMS noise is as low as 10 mV. The output will recover to 1% of its steady-state voltage within 1 ms for a step load change of 100% to 70% or 70% to 100%. Prices start at $2,650.
