application example energy-saving systems Within energy-saving systems, variable transformers are used so that single-phase and multi-phase alternating voltages and currents can be set steplessly between zero and maximum value under load. Variable transformers have a high self-heating and must therefore be cooled by continuous air supply. With the help of our vent-captors a controlled air supply/cooling is guaranteed. www.captor.de [email protected] [email protected] [email protected] Sensors GmbH Strohdeich 32 DE-25377 Kollmar Tel.: +49(0)4128 - 59T Fax: - 593 Sensors Ltd, 66 Eastbourne Road, Southport Merseyside PR8 4DU.
