High Voltage Insulation Tester
                                                    HV insulation under full control
                                                    
                                                    The S-25DC device is a universal high voltage tester. It stands out
                                                    in a special way. Not only by its modest dimensions. Due to its
                                                    internal rechargeable battery, it allows tests even when mains power
                                                    is unavailable.
                                                    
                                                    Capacitive objects, such as shielded power cables, will be correctly
                                                    and automatically discharged by the integrated discharge module if
                                                    an error occurs or the test time expires. A key switch, a switch-on
                                                    lock and a protective earthing circuit ensure maximum safety.
