SI48-1U (48V / 8-16A)

SI48-1U power systems have been designed to power 48V loads with the uninterruptible power of up to 16A (SI48-1U-16) or 8A (SI48-1U-8) loads in a system with a common positive bus.

The system of the device provides direct floating mode operation (rectifier units and powered devices are connected with rechargeable battery banks in parallel).

All the connections of the power system are made on the back panel, but the entire servicing process, including exchanging fuses, is done on the front panel.
