Switchgear Tripping Units

Overview

FAST Technologies battery chargers for switchgear tripping and closing have been developed in partnership with industry veterans. Designed to provide a continuous DC supply for operating switchgear and protection equipment, FSTU series units are supplied with status indictors, test points and alarms. The robust, reliable units, with a remote monitoring as an option are very simple to install and competitively priced.

One of the most critical components of a switch tripping unit is the battery technology used. FAST Technologies have integrated Nickel Cadmium cells due to thier inherent reliability over a 20 year plus service life, the chemistry also eliminates the fear of the unpredictable "sudden death" failure sometimes encountered with lead-acid batteries, as well as enabling the user to benefit from savings over regular replacement, maintenance and down-time costs.

A further advantage of the NiCd cells is that they provide high power output within a narrow voltage "window" and can also provide very high currents of up to 20 times the battery's nominal capacity.

Compared with VRLA batteries, NiCd batteries are also more tolerant of electrical abuse such as overcharging, deep or even complete discharge, and offer superior performance at extremes of temperature, with an operating range of -20 to +40C.

We also can supply a range of VRLA options to meet you exact application requirements.
