  PRESENTATION OF THE DEVICE 
 BASIC VERSION 
 
The SEFELEC 5x range is a range of products for performing dielectric tests and ground conti-
nuity measurements very simply and in a comprehensively.  
The SEFELEC 56-H and SEFELEC 506-H are used to perform tests of dielectric strength at 
powers of 50 VA and 500 VA respectively. The SEFELEC 56-D and the SEFELEC 506-D are 
combinations of a 50 VA or 500 VA dielectric strength tester and a Megohmmeter. The SE-
FELEC 56-S and SEFELEC 506-S combine the functions of insulation measurement, dielectric 
strength testing and ground continuity measurement in a single device.  
 
The SEFELEC 5x range devices allow the user to do the tests and measurements referred to 
above on all types of insulation, such as resin, porcelain, oil or plastic, as well as on finished 
products such as capacitors, transformers, switches, cables, connectors or electrical devices 
connected to the mains or powered by batteries. They allow the user to make ground continuity 
measurements in compliance with most of the existing standards in the fields of measurement 
devices, medical equipment, office equipment, machinery, etc. 
 
The SEFELEC range devices include a high-resolution graphic colour display with a touch 
screen for easier use. A single output for dielectric strength tests and insulation resistance 
measurements facilitates connection to the elements to be tested. Messages in colour indicate 
the outcome of the tests visually, simply and without any possibility of error.
