ACS880-307 Diode Supply Unit

Brand: ABB Group

Built on our all-compatible architecture these diode supply units convert three-phase AC voltage to DC voltage in non-regenerative drive systems. 

The units are specifically constructed to save space, cabling and installation costs and have in-built AC chokes for harmonics mitigation. 

There are two different diode supply unit types, an uncontrolled diode supply unit (D6D to D8D) and a half-controlled diode supply unit (D7T to D8T). 

The uncontrolled diode bridge is typically used in low power drive systems and it is a simple and robust supply for common DC bus configurations where the inverter units have internal charging. 

The half-controlled diode bridge is typically used in high power drive system and has built-in thyristor to charge the inverters connected to the common DC bus.
