48 VDC 33.5 A Enclosed Supply

This NShi server chassis is an enclosed switching power supply delivering 48 VDC at 33.50 A for a total of 1608 W. It accepts a wide AC input range from 90 VAC to 264 VAC at 47 Hz to 63 Hz with active PFC. The desktop form factor uses lug terminal female connectors for secure wiring. It suits integrators building rack or bench systems that need a single high-current 48 V rail.

Suited for Fixed 48 V Loads

This unit fits builders who need a single 48 V output at up to 33.50 A continuous current. It is not for systems requiring multiple voltage rails such as 12 V, 24 V or 36 V simultaneously. Buyers who need redundant or hot-swap power modules should look elsewhere. The fixed desktop enclosure also limits use in compact 1U or blade environments where a different form factor is required.

Lug Terminal Female Output Connection

The output connector type is lug terminal female, which determines cable termination and current handling. Installers must use correctly sized lugs and torque them to the manufacturer specification for safe operation at 33.50 A. If your wiring harness uses a different connector style, an adapter or custom cable assembly will be needed before the supply can be commissioned.

Questions about this item

How is the lug terminal female output connector attached to the power supply?

The lug terminal female connector is the fixed output interface on the 1608 W unit; secure cables with ring lugs and tighten the terminal screws to the specified torque to avoid loose connections.

What maintenance will the internal fan require over time?

The internal cooling fan should be cleaned of dust every 6 to 12 months and replaced if bearing noise appears, as airflow loss will trigger thermal protection on the 1600 W supply.

At what input voltage does the power supply reach its 1608 W limit first?

At the minimum 90 VAC input the supply draws maximum current, so sustained 1608 W operation is constrained by the AC circuit capacity before any other limit is reached.
