WEAG EVP100D 100A Digital Automatic Transfer Switch (ATS) with Priority Phase Selection – Best ATS Price in Bangladesh | STCMart

Looking for a 100A Digital Automatic Transfer Switch (ATS) in Bangladesh that can intelligently select the most suitable phase and protect your electrical loads from abnormal voltage and overcurrent conditions? The WEAG EVP100D 100A Digital ATS with Priority Phase Selection is a smart power-management solution designed for single-phase loads supplied from a three-phase electrical network. Available from STCMart, a trusted electrical and solar products seller in Bangladesh, the EVP100D combines automatic phase selection, voltage monitoring, current protection, digital display, and automatic recovery in one compact device.

Unlike a conventional Automatic Transfer Switch that simply changes between two separate power sources, the WEAG EVP100D Electronic ATS uses a dual input and single-phase output architecture. It continuously monitors the available phases and automatically selects the preferred healthy phase according to the configured priority sequence. This makes it particularly useful for Bangladesh applications where single-phase loads may experience unstable or unavailable phases in a three-phase distribution system.

100A Digital ATS with Priority Phase Selection

The standout feature of the EVP100D 100A Digital ATS is its Priority Phase Selection function. Users can configure a preferred phase sequence, allowing the device to select the priority phase when it is within the acceptable operating range and automatically move to a reserve phase when the preferred phase becomes abnormal or unavailable. WEAG specifies priority settings including configurations such as L1-L2-Auto.

This functionality can be extremely useful for homes, offices, shops, commercial buildings, and other single-phase loads supplied from three-phase utility networks.

For example, if your connected single-phase load is normally supplied from Phase L1, but L1 experiences an abnormal voltage condition, the EVP100D can transfer the load to an available reserve phase according to its configured priority logic. WEAG specifies a switching delay to the reserve phase of less than 0.2 seconds.

Digital Voltage & Current Monitoring

The EVP100D is more than a basic changeover device. It integrates intelligent monitoring functions and provides real-time electrical information through its digital display.

The device is designed to monitor operating voltage and current while providing protection against abnormal electrical conditions. This makes troubleshooting and system monitoring easier compared with a conventional mechanical transfer switch.

For customers looking for a Digital ATS 100A Bangladesh solution with integrated monitoring and protection, the EVP100D provides multiple functions within a single compact unit.

Overvoltage & Undervoltage Protection

Voltage fluctuation is a common concern for electrical equipment. Excessively high or low voltage can affect sensitive appliances, electronics, motors, inverters, and other connected loads.

The EVP100D incorporates adjustable overvoltage and undervoltage protection. For 220V systems, WEAG specifies an overvoltage setting range of 230V–300V and an undervoltage setting range of 80V–210V. The device can disconnect or transfer the load when the monitored phase goes outside the configured limits.

This makes the EVP100D particularly useful for electrical installations where stable power quality is important.

Overcurrent Protection

The EVP100D also integrates overcurrent protection, helping protect connected loads against excessive current conditions. The model is available with a 100A rated operating current, making it suitable for higher-load single-phase applications when correctly sized according to the overall electrical system.

It is important to note that the ATS’s integrated protection should be considered as part of the overall protection design rather than a replacement for properly coordinated upstream/downstream circuit protection.

Automatic Recovery Function

Another useful feature is automatic recovery. After an abnormal voltage condition is cleared and the preferred power source returns to an acceptable condition, the device can automatically restore operation after the configured delay.

WEAG specifies an adjustable auto-reclosing delay from 1 to 600 seconds, as well as a return delay to the priority phase from 1 to 600 seconds. This allows users to configure recovery behavior according to the requirements of the installation.

Ideal for Bangladesh’s Distribution Systems

The WEAG EVP100D 100A Digital ATS is particularly useful in Bangladesh because many residential, commercial, and industrial buildings receive dual power source utility power while individual loads may operate on single-phase supply.

Instead of manually changing a load from one power source to another when a source becomes unavailable or unstable, the EVP100D can automatically manage the available power source according to its programmed priority.

This can reduce manual intervention and provide a more convenient power-management solution for critical single-phase loads.

Applications of WEAG EVP100D 100A Digital ATS

The EVP100D can be used for a wide range of applications, including:

• Residential single-phase loads
• Commercial buildings
• Offices
• Shops and showrooms
• Small businesses
• Single-phase industrial equipment
• Refrigeration systems
• Pumps and motors
• Air-conditioning systems
• Telecom and networking equipment
• Sensitive electronic equipment
• Backup power distribution
• Three-phase grid to single-phase load management
