Technical data, dimensions and installation notes for the SIME Brakes AC32-50 CP 700V power supply used with 4CA, 3WD, 3CA and 2CA disc brake calipers.
This leaflet (No M10005-03, reference T10005-03-B) gives technical data and dimensions for the AC32-50 CP 700V compact power supply, which operates on two-phase 525 to 690 V AC mains and is used with Stromag France disc brakes fitted with a 50 V coil. It covers electrical data, EC marking of conformity, operating conditions, options and the settings of potentiometer PT1 and switch S1.
The leaflet also lists data for each caliper type (4CA, 3WD, 3CA, 2CA), including maximum number of calipers, resistance at 20 °C per caliper, actuations per hour, mains current absorbed, maximum connecting cable resistance and length, and the fuses or circuit-breakers to be provided ahead of the control contactor. An electrical danger warning states that the product is not insulated and must be installed by qualified personnel. Similar versions of the same leaflet for AC32-50 units on 230 to 500 V AC mains with a steel case are reproduced in the file.
