WATSN Dual Power Distribution Box

Fiber and communications infrastructure knowledge brief Published 14 May 2025

Prepared for preliminary research by the ENSAA knowledge desk. Confirm optical interfaces, port or core capacity, electrical input and output, enclosure protection, thermal design and installation limits against current standards and product documentation.

The WATSN Dual Power Distribution Box is an automatic transfer switch (ATS) designed to ensure reliable power continuity between two sources, supporting multiple operation modes and high current capacities.

Overview

The WATS

N Dual Power Distribution Box, also known as a WATSN ATS, is engineered to manage the transfer of electrical power between two sources, such as dual commercial supplies or a commercial supply and a generator. It ensures continuous power supply and circuit reliability even during power interruptions, optimizing energy management in residential, commercial, and industrial applications.

Key Features

Current Ratings: Available in 32A, 63A, 100A, 160A, 200A, 250A, and 400A, supporting 2P, 3P, and 4P configurations. Operation Modes: Includes automatic change with automatic recovery, automatic change with manual recovery, standby for each other, and manual control. Controllers: Type A (built-in): Transfers between two commercial power sources with adjustable transfer delay.

Type B (external): Adds support for generator transfer, parameter settings, display panel, and optional communication functions. Protection and Reliability: Equipped with standard trips for fault protection, mechanical and electrical interlocks for transfer reliability, and isolated power modules to improve voltage withstand levels. Standards Compliance: Meets IEC and GB standards, CCC certified, and passes EMC testing.

Applications

The WATS

N Dual Power Distribution Box is suitable for: Commercial buildings requiring uninterrupted powerIndustrial facilities with backup generatorsData centers and critical infrastructureAny system needing reliable dual-source power management AdvantagesHigh reliability: Can make, carry, and break currents under normal and overload conditions without damage. Flexible operation: Multiple modes allow seamless integration with different power setups. Safety: Mechanical and electrical interlocks prevent accidental switching and ensure safe operation.

In summary, the WATSN Dual Power Distribution Box is a robust, versatile ATS solution that guarantees power continuity, safety, and compliance with international standards, making it ideal for both commercial and industrial power management systems.
