The need to have a reliable power source 24x7 is more important than ever in today’s business environment. Supplying critical and clean power without interruption, the EA933 series offers high performance Uninterruptible Power Supplies for servers, networking, and other high availability equipment. The EA933 series are high frequency UPS’s with three phase in and three phase out, adopting full digital control technology. With advanced modular design the compactness of layout is ensured and enhances the performance of the unit. The electrical performance of the EA933 series is advantageous and protection of software and hardware of it is perfect. It is applicable for different power grid and can supply safe and reliable power for different loads.The EA933 series can also be configured to provide a single phase output which simplifies power distribution to your critical load when used in smaller business environments.


True Online Double Conversion

The EA933 applies true online double conversion technology, providing users with clean and high quality power. The zero transfer time ensures that power is supplied without interruption, thereby fully protecting mission-critical devices.

Wide Input Voltage Range


The EA933 provides stable power to the connected devices under unstable power conditions. The EA933 is capable of handling a wide input voltage range, supplying clean power in extreme circumstances.


Pure Sine-wave

The pure sine-wave output of the EA933 series guarantees compatibility with all kinds of loads, providing perfect power protection for versatile applications such as high performance, industrial and other mission critical applications. Emergency Power Off (EPO) FunctionThe EA933 is equipped with an Emergency Power Off function, providing users with a way of immediately shutting down all output power from the UPS in the case of emergencies such as fire, flood, and overheating equipment.


LCD Touchscreen

The EA933 is provided with user friendly 5.7 inch LCD touch wide screen display, situated at the front of the EA933. It provides you with instantaneous information about values such as input and output voltage, input and output frequency, load in percentage terms, and available battery capacity. The display can be controlled with the touchscreen application.

Full Digital Control

The EA933 UPS systems offer advanced technologies which significantly increase both performance and reliability. Two high speed digital signal processors ensure the high quality of the power supply and create a high input power factor.


Power Factor 0.9

The EA933 series are equipped with a power factor of 0.9, making the EA933 an efficient and energy saving UPS sytem.

Frequency Auto-Sensing

The EA933 is equipped to fit all environments and every configuration.

Making sure it is maintenance and user friendly design the EA933 is equpped with automatic frequency sensing; allowing the UPS to recognize the frequency (50Hz/60Hz) and automatically synchronize this with the output. Because of its flexible design it is also possible to install frequency conversion of 50Hz input and 60Hz output, or any way customer demands.

Bypass Switch

Maintenance work can be carried out through the use of the manual bypass switch. This completely isolates the UPS’s internal components, so that minor maintenance work and repairs can be conducted without interruption to supply.


Optional External Bypass Switch

The external bypass switch ensures that there is continuous power to the equipment by completely isolating the UPS bridging between it and the mains. Using this tool, users are able to carry out substantial interventions and even change a UPS without interruption to supply.Manual Bypass Switch located on the backside of the EA933

Today’s demands go further than needing a reliable protection for your equipment. It needs to be high efficient, flexible and more over: cost effective. The EA933 combines all those above mentioned providing customer the most complete and cost effective solution without losing a percentage of the reliabilities and efficiency.

All the modules of the EA933 are designed to be hot swappable.The individual kVA modules which will be placed in the rack along with monitoring and charge modules are all hot swappable enabling the MBR to be most efficient as possible.


Modularized Subsystem Design

Through the modularized subsystem design on the EA933, all critical components are equiped to be redundant; when one fails the backup component takes over, increasing the reliability of the UPS.

Ease of Acces

The EA933 UPS series designed to be efficient in more than one way. The UPS and battery cabinets are easily accesible for maintenance by simply opening the front door and pulling out the trays of components, significantly reducing the MTTR (Mean Time to Repair).

Parallel The EA933

systems ensures maximum availability through the use of its advanced parallel system technology. It is easily set up to have a different number of kVA modules inside the UPS cabinet in redundancy via the LCD display. To be as cost efficient the EA933 also has got the option of using the battery packs in parallel; meaning a shared battery cabinet. In an N+1 redundant configuration, there is at least one more UPS module than is required to support the load. As a conjoined system, each UPS is ready to take over the load from another whenever necessary, without disrupting protected loads.



Start Up Service
