Product Description

The Bosch VMA 20 KB 001-D is a power supply module for Servodyn-D systems. It is a power module with internal ballast switch. The rated current output of the module is 20 Amps at 45 degrees Celsius. The supply voltage for the module is 380 to 415 Volts AC. The VMA 20 KB 001-D is a standard variant module without a digital interface or additional functions. The power supply is air cooled. The supply modules are configured for required rated power. A corresponding reserve should be provided for short-term overloads. The rated power of the power supply is determined by the rms rated current of the module and the rated voltage at the installation site. In case of heavy loads it should be verified whether the peak output made available by the VMA 20 KB 001-D module will be sufficient.

The peak output for short-term overloads VMA 20 KB 001-D is limited by pre-loading of the power section. The DC link voltage for the VMA 20 KB 001-D is 670 Volts AC. The rated current is 23 Amps. The rated power is 16 kVA at 45 degrees Celsius which derates by 0.62 Watts per K between 45 and 55 degrees Celsius. The peak output of the VMA 20 KB 001-D is 20 kVA. The maximum one-time braking energy is 6500 Watts and the maximum continuous braking power is 400 Watts. The power demanded by the VMA 20 KB 001-D from the 24 Volts power supply is 1 Amps. The rated maximum power loss inside the switch cabinet is 220 Watts. Weight of the power supply module is 15 kilograms. Width of the power supply module is 100 millimeters. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
