Technical capability
We develop STS control electronics, power-source monitoring and embedded software for customer power-management projects. Transfer decisions are assessed alongside load requirements, source conditions and the system's other protective devices.
Your project, your product
We may work with a confidentiality agreement (NDA) before sharing technical details. At the end of the project, we deliver the source codes, design files and technical documents we have developed to you.
VOMRO engineering approach
In static transfer switch control, the acceptable state of each energy source and the transfer conditions of the load must be defined. Voltage, frequency, phase relationship and error information are the inputs of the decision mechanism. These limits are not chosen independently of the usage scenario.
Control electronics work with the power stage, measurement circuits, user interface and supervisory system. VOMRO clarifies the layers it will develop, interfaces and validation responsibilities at the outset.
Evaluation periods and thresholds for measured values are defined. Transient deviations are distinguished from persistent faults, with defined behaviour for interrupted or invalid measurements. A source becoming acceptable again is a separate state. Decision logic that prevents unnecessary transfers is structured for testing.
The preferred power source, automatic or user-commanded operation and actions permitted during faults are represented in a state machine. Command compatibility with the power stage, interlocks and feedback are examined together. The monitoring dashboard can explain why a transfer was rejected as well as report command results.
There is no universal promise of interruption-free transfer; the target load's tolerance and system architecture govern. Mains electrical safety, isolation, thermal behaviour and protection coordination are assessed. A working control prototype does not mean the final STS has completed its required safety and conformity tests.
How it works
Not every project looks the same; however, the measurable requirement, controlled revision, and field verification steps remain unchanged.
We document the power sources, load tolerances and control limits.
We develop measurement, state machine and power stage interfaces.
We evaluate normal operation, loss of a power source and its restoration.
We organise the source files, interface definitions and test findings together.
Frequently asked questions
The technical scope, deliverables and test plan are clarified together according to the requirements of your project.
Yes. A separate development scope can be created by examining the technical information, signal levels and control requirements of the existing power stage.
Power source status and event logs can be sent to a supervisory system. Permissions and safety limits for remote commands are defined separately from the monitoring function.
We can work with NDA. We deliver the source code, design and technical files of the project at the end of the project; We determine the scope and formats together at the beginning.
Yes. We can complete the NDA arrangements together before you share your project's technical details.
