DIGI GTW-WD By Gelco Electronics: Intelligent Protection For Modern Motor Systems

by Gelco Electronics on May 18, 2026

In agricultural and industrial environments, motors and pumps are constantly exposed to unpredictable electrical conditions. Voltage fluctuations, phase failures, overload situations, and dry-run conditions can severely impact equipment performance and lifespan. In such situations, having a reliable motor protection system becomes essential rather than optional.
The DIGI GTW-WD by Gelco Electronics is designed to offer advanced protection, intelligent monitoring, and dependable performance for three-phase submersible motors and pumps. Combining digital technology with practical functionality, the starter delivers enhanced safety and efficiency for agricultural, domestic, and commercial applications alike.

Designed for Demanding Conditions:
The DIGI GTW-WD is specially engineered for operating submersible motors and pumps used in irrigation systems spread across large farmlands and remote areas where power supply conditions may not always remain stable. Its robust functionality also makes it suitable for domestic water systems and commercial pumping applications that require uninterrupted performance and reliable motor protection.
Unlike conventional starters that offer limited safety features, the DIGI GTW-WD actively monitors the electrical supply and motor conditions to ensure smooth and secure operation.

Advanced Protection for Longer Motor Life:
One of the strongest advantages of the DIGI GTW-WD is its comprehensive protection system. Motors are often damaged due to overload conditions, voltage imbalance, dry running, or operating on faulty electrical phases. Over time, these issues lead to overheating, winding damage, and expensive repairs.
The DIGI GTW-WD minimizes these risks through intelligent electronic protection. It continuously monitors the system and protects the motor against overload, under-voltage, over-voltage, and phase failure conditions. This not only increases the operational life of the motor but also significantly reduces maintenance costs and downtime.
Its dry-run protection feature is particularly beneficial in areas where water availability fluctuates frequently. By preventing the motor from operating without sufficient water supply, the system safeguards the pump from unnecessary wear and damage.
Intelligent Water Level Monitoring:
Another standout feature of the DIGI GTW-WD is its ability to automatically monitor and manage water levels. The starter intelligently controls motor operation depending on the water availability and system requirements, reducing the need for constant manual intervention.
For farmers and facility operators, this means improved convenience, better water management, and uninterrupted irrigation cycles. The automation also improves overall efficiency by ensuring that the motor operates only when required.
Digital Monitoring for Better Accuracy:
Traditional analog systems often make it difficult to accurately monitor motor performance. The DIGI GTW-WD solves this issue with a digital display that provides reliable operational readings.
The system displays the current flowing through the motor, allowing users to easily monitor performance and identify abnormal conditions before they become major issues. This digital accuracy improves operational confidence while simplifying troubleshooting and maintenance.
Reliable Phase Protection for Unstable Power Conditions:
In many regions, especially rural and agricultural areas, unstable power supply remains a major challenge. Motors operating under single-phasing or phase imbalance conditions can suffer severe damage if not protected properly.
The DIGI GTW-WD offers complete phase monitoring and protection, ensuring that the motor remains safe even when electrical conditions fluctuate. The system actively checks all phases and prevents operation during unsafe conditions, helping avoid costly motor failures.
This level of intelligent protection makes the DIGI GTW-WD far more reliable than traditional starters that lack advanced monitoring capabilities.
Compact Yet Powerful Design:
Despite offering multiple advanced features, the DIGI GTW-WD maintains a compact and durable design suitable for demanding environments. Built with practicality and long-term use in mind, the starter combines performance with ease of installation and operation.
Its efficient design makes it suitable for a wide range of motor control applications without occupying excessive space.
Technical Specifications:
The DIGI GTW-WD operates on an input supply of 415V and 50Hz frequency, making it suitable for standard three-phase motor applications. It supports a load capacity of up to 20 Amp and can efficiently operate motors up to 7.5 HP.
The starter features adjustable electronic overload protection ranging from 2–20 Amp, ensuring accurate and customizable safety settings according to the motor requirements. It also includes over-voltage protection above 490V and under-voltage protection below 340V, helping safeguard motors against unstable electrical supply conditions.
To further enhance equipment safety, the system is equipped with adjustable electronic dry-run protection ranging from 1–18 Amp. This prevents the motor from operating in low-water conditions and reduces the risk of overheating and damage.
The DIGI GTW-WD comes in a compact structure with dimensions of 23 cm in length, 11 cm in width, and 27 cm in height, while weighing approximately 2.368 kg. Its compact yet durable construction makes it easy to install while ensuring long-term reliability in demanding operational environments.
A Smart Investment for Modern Applications:
The DIGI GTW-WD is more than just a motor starter—it is a complete protection and monitoring solution. For users who rely on uninterrupted motor performance, especially in agriculture and water management systems, investing in intelligent protection can prevent significant losses in the long run.
By combining automation, digital monitoring, and advanced electrical safety features, Gelco Electronics has created a product that delivers both reliability and peace of mind.
