ECOTAP® VPD® Control – Compact control unit for reliable voltage regulation
The ECOTAP® VPD® Control measures the voltage on the LV side and controls the ECOTAP® VPD® on-load tap-changer by actuating the motor drive. Intuitive operating and display elements support efficient on-site operation. For seamless integration into specific network environments, the unit includes a MODBUS RTU interface.
Specially configured
- Available in specific variants (e.g., with special Modbus parameter settings for e.on group) or as Control DS with dynamic adjustment of the voltage setpoint
- Compatibility with all variants of the ECOTAP® VPD® on-load tap-changer
Easy commissioning
- Plug-and-play: Connection completely via coded plug-in systems to prevent incorrect connections
- Parameterization possible without a laptop through direct setup of the device on-site
Intelligent voltage regulation
- Automatic operation with single-phase voltage control algorithm
- Extensive status indicators on the display with automatic updates to highlight key parameters
Compact and flexible design
- Space-saving dimensions: only 10 cm wide and 35 cm high
- Flexible installation options: on the transformer, in the control cabinet, or directly on the busbar
Suitable for all versions of the ECOTAP® VPD® on-load tap-changer®
The ECOTAP® VPD® Control product family comprises three variants, each tailored to different application requirements. All variants feature automatic voltage regulation, intuitive operation, and compact design. However, the Control DS offers additional features such as an input for single-phase current measurement and dynamic setpoint adjustment depending on active power flow. The e.on variant is specifically preconfigured for distribution network operators of the e.on group with corresponding Modbus parameter settings.

FAQ - Frequently Asked Questions
What else do I need in addition to this control unit?
This control unit provides the switching pulse for the motor drive, which switches the ECOTAP® VPD® on-load tap changer. These three elements turn a standard distribution transformer into a controllable transformer that can maintain the voltage within a defined voltage range. The control units can be used for all ECOTAP® VPD® on-load tap changers, including the single-phase versions.
What is the difference between the ‘Standard’ and ‘e.on’ options?
Both versions have the same functionalities. However, the ‘e.on’ version has different MODBUS settings for the applications of this distribution network operator.
What can I do with the MODBUS RTU interface?
This interface allows the control unit to be connected to an additional “Control PRO” unit or to a gateway including a MODBUS converter for remote communication. This enables data to be read out or switching commands to be issued externally. For commissioning, the control unit can also be connected to a laptop, from which data can be uploaded.
Can I replace old control units with new ones?
Yes, all control units supplied with the ECOTAP® VPD® load tap changer to date can be easily replaced with a new control unit. The dimensions are identical, as are the dimensions of all three variants.
