There are four versions available.
Maximum output current
SI48-1U2-151-ET- MF - 15A Single Rectifier
SI48-1U2-152-ET- MF - 30A Dual 15A Rectifiers
SI48-1U2-301-ET- MF - 30A Single Rectifier
SI48-1U2-302-ET -MF - 60A Dual 30A Rectifiers
All have four fused outputs.
The dc power system delivers uninterrupted DC power system to telephone exchanges, radio links and other telecommunication and data transmission devices and industrial automatics systems with a common positive bus.
The devices supplied by the power system must have an extended 48V supply voltage range due to the use of a battery bank.
The power system supports one valve-regulated lead-acid battery banks (VRLA) with a floating mode and bulk charging voltage compensation for ambient temperature and adjusts the compensation coefficient to the battery used.
The power systems are made in the form of a metal cassette with a height of 1U. Due to its design, the enclosure of the power system is designed to be mounted only inside a 19" rack.
The power system is delivered in a unit packaging including a main unit and:
• User Manual
• Temperature probes, 2 m long (2 pieces)
• Relay fault indication system connectors (2-pin connectors) (3 pieces)
• External alarm input circuit connectors (3-pin connectors) (1 piece)
Software (not included, as it is separate product) for remote control and operation of the power system.
Software is available to download.
Communications module is built in.
It will work normally straight buffer (rectifiers and the power devices are connected in parallel with the battery).
All connectors are located on the rear panel, but the whole service, including service fuses are possible on the front panel.
