ACS880-304 – liquid-cooled diode supply modules
|
Description
Built on our all-compatible architecture these diode supply units convert three-phase AC voltage to DC voltage in non-regenerative drive systems. The modules are specifically constructed to save space, cabling, and installation costs. There are two different diode supply unit types, a direct uncontrolled diode bridge (frame D8D) and a half-controlled diode supply module (frame D8T). The uncontrolled diode bridge is typically used in single drive configurations and it is designed to be connected to a dedicated supply transformer which acts as an AC choke. The half-controlled diode supply module is typically used in multidrive configurations, it has in-built AC chokes for harmonics mitigation and in-built thyristors to charge the inverters connected to the common DC bus. The supply modules can be connected in parallel for higher powers.
