HZF Series

HZF Series

The Indramat HZF combining filter is used at the mains connection of the power supply unit to suppress current leaks and provide interference suppression. There are three versions of the HZF filter, each with different requirements for the nominal current and losses.  This combining filter was designed specifically to be used with HVR supply modules and must be mounted either to the left or right of the supply unit. The supply line to the HZF must be shielded to avoid possible interference for optimal performance. Additionally, the connection for the DC bus must always be connected to the HZF filter in order to operate properly.
