Compact control unit for ECOTAP® VPD® on-load tap-changer
Achieve precise voltage regulation with ECOTAP® VPD® Control – the compact
control unit designed specifically for the ECOTAP® VPD® on-load tap-changer
(OLTC). Intuitive to operate and adjust – it continuously monitors low-voltage
levels and ensures optimal tap-changer performance, delivering stability and
efficiency for today’s dynamic power grids.
ECOTAP® VPD® Control is the dedicated controller for the ECOTAP® VPD®
OLTC, engineered to provide reliable voltage management in evolving grid
environments. By measuring voltage on the LV side and actuating the tap
changer motor-drive unit, it guarantees consistent voltage.
Its intuitive interface simplifies on-site handling, offering clear displays and easy
navigation for technicians. For advanced connectivity, the unit supports
MODBUS RTU communication, enabling seamless integration into existing grid
architectures and SCADA systems.
Compact yet powerful, ECOTAP® VPD® Control combines robust design with
smart functionality – making it the ideal choice for utilities and industrial
applications seeking cost-effective voltage regulation without complexity.

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.
