Telecome DC power supply and rectifiers systems by ETC Power.

SDC 500

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 a system controller which allows to fully remote control the 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 a 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).

	SDCB 250 The SDCB 250Z power supply system is intended for uninterruptible supply of 48dc loads by direct current in direct full-float operating mode. The construction of the system using cooperation of rectifiers type PDC 48/41-200w and batteries under control of advanced Pi1 controller. The SDC system was placed in an IP54 outdoor cabinet resistant to harsh climatic conditions. Cabinet provide protection devices installed in it from the negative influence of atmospheric factors for the European dimate zone according to ETSI EN 300 019-4 class 4.1 standard. The SDCB 250 system is supplied from three-phase AC supply line. Failure of one or two phases of mains supply does not cause the whole power supply system to be switched off (individual rectifier units are supplied from different phases).
