Abstract
Details of Electrical and Electronic Apparatus with Applications in the Maintenance and Operation of Aircraft, Missiles and Space Vehicles. K.P.E. Controls Ltd., of Progress Road, Leigh‐on‐Sea, Essex, U.K., have introduced what is believed to be the smallest commercially available solid state temperature control instrument, self‐contained for solid state proportional control of powers up to 1 kW. The instrument is constructed in the Elite 4 panel mounting instrument case which has an accurately calibrated 270 deg. dial for setting of the required temperature. The 5 in. long instrument case houses modern transistor circuitry and includes one Triac or two thyristors for proportional control of output loads up to a maximum of 1 kW at 240 volts a.c. Control of higher powers may be achieved by using commercially available thyristor stacks mounted external to the instrument.
