The DYNAMIC BRAKE is also supplied in the UNIVERSAL version, i.e. it can also be used with non-PAE INVERTERS. In this configuration, the indication of the current is obtained directly from the reading of the current of a power supply phase of the inverter. The conductor of the phase of which the current is detected is not interrupted but it is sufficient to insert it in the appropriate duct for non-contact reading. The other connections remain the same as the NCT238A version.
