Getting the power to where it is needed

19 October 2005 Power Electronics / Power Management

Sinetech recently announced further products which advance the power resources available to the telecoms industry. Sinetech is a Randburg-based supplier of a wide range of general power protection and power conversion products, and is the sole distributor for European inverter manufacturer CE&T.

Says Sinetech general manager, Herbert Teubner, "Key among the CE&T products is the Miniflex, Arcon and RDI modular inverter products. The Miniflex range is a state-of-the art rack-mounted system from 2 kVA up to 6 kVA with inverter modules of 1 kVA, an input range of 48 V d.c. and outputs at 120 or 230 V a.c.

"The flexibility of the system in a telecoms environment makes it a prime choice for the industry," he notes. "With the Arcon and RDI products, standalone or parallel products with unique characteristics provide telecoms users with huge flexibility. Systems are available from 3 kW up to 72 kW."

Users can choose either totally programmable input or output voltage at a variety of VA ratings with the ARCON range, or parallel a number of units at various VA ratings with the RDI product. "The RDI Telecom Series are 100% digital inverters which provide AC current to utilities by taking power from a range of DC sources. With a full range of options from small standalone applications to large data centre systems, we are able to provide almost any inverter solution required for today's demanding markets," adds Teubner.

He says that the products fully meet international standards and in Africa present a highly effective way to provide AC power from a DC source. There have been active enquiries from customers in Nigeria, Sudan and Uganda, says Teubner.

New to CE&T's range is RLP (remote line powering) which makes use of original copper telephone lines that have been replaced by fibre-optics.

"Using the 'old' cables with new technologies results in a unique power transmitter that ensures reliable power to a remote site," Teubner says. "Supplying 48 V d.c. up to a distance of 10 km, RLP is a safe and effective means of remote power. RLP is already in use in many African countries where reliable power is an issue."
