DC power systems

The offer of our company is being updated with new products, which are adjusted to current situation on market of telecom power supplies.

Our designs are basing on advanced, constant-power, modular rectifiers. All rectifiers are designed with hot-swap philosophy (all DC and AC connections are located on rear sockets). Rectifiers are individually supervised by system controller, which allows to full remote control of power system.

Concerning variety of clients needs (wide range of load power, back-up time, system cabling and mounting), Our company offers telecom power supplies in different versions with wide range of optional equipment (e.g. small power supplies are made as ready to fit in 19"/21" standard cabinets or in wall-mounted enclosure).
Systems installed in 19" standard may be prepared as Front Terminal (all terminals and connectors are located on the front panel of the system) or in version with terminals located on the rear panel of the system.
