€416.00 tax excl.

Ultra-insulated 4kVA three-phase transformer with metal box that allows the adaptation of tension between line and receiver in three-phase systems, 400Va to 400Vac (generates neutral). It provides separation between primary and secondary circuits, and by means of a safety electrostatic display, filters and grounds unwanted signals and disturbances. Mounted in metal box with an IP-23 degree of protection.
