Emax 2 Harness automatic double power conversion system

Intelligent and efficient

New third-generation technology - Emax 2 Harness dual power conversion system

- Embedded control system for more efficient power switching

- Intuitive user interface and user-friendly human-machine interaction

- Comprehensive safety features

The Emax 2 Harness dual power conversion system is designed for ‘two inlets and one busbar’ power supply lines.

Using ABB's latest third-generation circuit-breaker power conversion solution, the Emax 2 Harness eliminates the need for a traditional external stand-alone controller.

Emax 2 Harness can be directly through the intelligent off-trigger embedded logic to achieve efficient cooperation between the circuit breaker control, while supporting a variety of control modes, wiring, and so on.

The Emax 2 Harness supports multiple control modes, simple wiring, high reliability, shorter changeover times and intuitive control.

Emax 2 Harness is a high-performance automated power conversion system on the Emax 2 Ekip intelligent protective circuit breakers.

It provides safer and more reliable power switching without the need for additional control equipment, whilst providing circuit protection.

In industrial and power applications where efficiency and performance are delivered through digital communications, ABB is reinventing the way digital systems are embedded to help users achieve more efficient, safe and reliable power conversion.

ABB is reinventing the way digital systems are embedded to help customers realise more efficient, safe and stable power system solutions.

Efficient and simple control systems: smart circuit breakers with integrated embedded logic for shorter changeover times.

Simple connectivity: no need for a separate external controller for the circuit breaker, eliminating the need for complex wiring to external protection devices.

Higher Reliability: Ekip release provides a wide range of circuit breaker protection to ensure higher reliability. In the event of a fault, local and remote alarms can be realised, so that faults can be dealt with quickly.

The Emax 2 Harness automatic double power conversion system is equipped with power supply voltage and frequency detection functions.

In addition to the conventional conversion function, it also provides the closed-loop control function (parallel conversion) required by power plants and industries.

This ensures uninterrupted power supply for special applications and brings new solutions for power electronics, semiconductors, airports, petrochemicals, data centres and other industries.

Control Functions

The Emax 2 Harness dual power conversion system comes standard with the Touch intelligent tripper, which not only provides full mains circuit protection, but also supports multiple power sources.

switching functions:

- Automatic switchover - self-recovery - no self-recovery

- Manual changeover (not in parallel)

- Parallel switchover

The system can be fitted with control buttons and mode changeover switches mounted separately on the instrumentation door of the switchboard cabinet.

Manual/automatic/parallel switching is achieved by means of a mode switching button.

The system can be switched automatically according to a predefined procedure or switched to manual mode to exit automatic operation.

In the event of planned maintenance or power failure, manual parallel switching of the power supply is also possible to ensure that important loads are not interrupted by the switching process, thus ensuring continuity of the power supply.

Measurement functions

The Emax 2 Ekip Touch is equipped with a measurement module, which automatically collects and measures the status and parameters of the power supply and displays them visually on the circuit breaker's LCD screen.

Status indication

The Emax 2 Harness system can also be equipped with a status display function to show the operating status of the system to the user, which is convenient for on-site management.

Voltage Status Indication: The line voltage status of power supply 1/power supply 2 can be indicated by the LEDs. If the power supply voltage status is normal, the indicator light will be always on; if the voltage is abnormal (under/over-voltage), the indicator light will not be on.

Circuit breaker status indication: The status of power supply 1/power supply 2 (normal/abnormal) and the status of CB1/CB2/CB3 actuating circuit breakers (bright - closing; non-bright - opening) are visually displayed in the form of a single-line diagram of the system.

Synchronisation status indication: In parallel conversion mode, the synchronisation conditions (voltage/frequency/phase angle) of the two power sources of Power 1/Power 2 need to be met before parallel operation can be carried out.

Synchronisation indicator is on, it means that the two power sources are in synchronised state and parallel operation can be carried out; if the synchronisation indicator is not on, the two power sources are in unsynchronised state, then the circuit breaker will start safety blocking.

At this time, the executive circuit breaker starts safety blocking, and the switch can not execute the closing command in parallel operation mode to ensure the safety of the line.

Alarm Indication: The alarm indicator lights up when abnormal release occurs in the line.

Communication function: After installing communication module, the circuit breaker can have communication function, which can realise remote communication and intelligent control.
