Rated at 4kW, 700DNG40-24-8 is smaller and, at 450 to 900Vdc, operates over a wider input voltage range than its 700DNC40-24-8G predecessor.

Size is 285 x 55 x 355mm including protrusions, and it weighs 4.5kg.

The galvanically-isolated output is 28V at up to 143A, and can be trimmed across 20-30V via CAN but with 10bit resolution. Up to eight can be paralleled for more current.

Efficiency is up to 94% (700Vdc in, 28Vout, 143A load).

To dump heat, the PSU needs to be plumbed into a liquid circuit, requiring an anti-freeze/water mixture at 10-20 litre/min at up to +65°C (+85°C with reduced electrical output).

Protections include output over-current, over-temperature, output over-voltage and reverse-polarity.

Sealing is to IP67 and IP6k9k

Applications are foreseen in construction, mining and marine equipment, as well as on and off-highway vehicles.

The company will be at the Battery Show North America next week (12-14 September, stand 936).
