Using Technology True On-Line Double Conversion Technology, the Cover Energy 30kVA UPS 30000VA MZ 30 Online Unit provides the perfect output voltage parameters, regardless of the input voltage and the load. It can be used in applications such as; Large computer networks, Data processing centres, Industrial facilities and equipment, Laboratory equipment, Telecommunications, Automation and control systems.

Its IGBT Rectifier technology is the most advanced and provides THDi load and a high-power factor. An automatic bypass provides continuous loads supply in critical conditions, such as overheating or inverter failure. Having a modular design and a “hot swap” feature on both the power and the bypass module makes maintenance or a repair on the inverter supply simple.

An automatic bypass ensures uninterrupted power supply (UPS) to critical loads such as overheating or failure. As well as a service bypass to allow servicing of the device without switching off powered receivers. A separate power supply bypass track provides the ability to provide a reserve power source for receivers. Even in the event of a device failure or UPS protection in the main track.

Communication Interfaces on the Cover Energy 30kVA UPS 30000VA MZ 30 Online Unit

There is a RS485, ModBus to monitor and manage the operation of the power supply and receivers, also a DryContact in / out relay contacts for support with the BMS systems. Also, the unit comes with a SNMP integration with systems management network (NMS).

There is a remote emergency power off (REPO) to provide remote shutting off of the load and UPS in the case of emergency. As well as an emergency power off (EPO) on the UPS, provides very quick shutting down of the load and UPS. Lastly, an against fire switch (LEPO) on the control panel enables immediate disconnection of power from the receivers.

A touch control and monitoring panel gives the possibility of diagnostics of parameters and operation mode of the power supply and also enables logging of events.

Compact Design and Efficiency of the Cover Energy 30kVA UPS 30000VA MZ 30 Online Unit

The compact dimensions of the Cover Energy 30kVA Online UPS Unit means that it takes a small area up. High efficiency (>96%) reduces heat dissipation and limits power consumption costs. An ECO-Mode gives the prospect of significant reduction in running costs and heat emissions. With a possibility to program periods of time when UPS will work in ECO mode, for example during night.

The unit has automatic diagnostics with FTM (Fault Trace Management) and fully digital control (32 bit DSP x2) guarantee, full device efficiency, with a component control and operating parameters without the need for user intervention.

Simple to use – easy to connect to the network and simple switching on and off the device does not require special qualifications from the user. Advanced battery management guarantees optimal charging and use of batteries, to increases their lifespan and lowers operating costs.

The excellent quality of the output voltage is achieved thanks to the use of the IGBT inverter using highly advanced PWM control technology. This ensures that voltage with a stable parameter is supplied, regardless of the power disturbances and the type of devices being powered.

Configurable work parameters – nominal voltages, frequencies, preferred modes of operation, communication method – significantly broadens the range of possible applications.

The unit is ready to accept 2 x 36 x 9Ah batteries – contact us for available options.

Redundant configurations:

– redundant work for increased reliability

– capacitive parallel operation for increased power

– HotStandby work

When will I receive my order?

In most cases, a product on our website will give you an indication of the current stock availability, but shipping is not uniform for all products. We maintain fantastic relationships with all of our suppliers and we aim to get products to customers within 3 business days of the order being taken. This availability is based on information from our suppliers and from sales and supply patterns. The availability information given is a guide only and not a guarantee as there are external factors that we may not have control over.

Coronavirus Update – UK couriers and transport companies will not currently guarantee delivery times and we are seeing a slight delay in deliveries – please bear this in mind when ordering.

1500rpm machines or larger diesel gensets however are typically priced on application and all depend on the destination. We will be happy to quote on any large diesel generator and discuss your needs over the phone or via email.

Most orders placed before 12pm on a business day will be shipped from our suppliers on the same day provided the product is in stock. If you need to be certain an item is in stock and available, or if you need a lead time, it’s worth calling our sales team on 01329 722390. Pricing for extended shipping areas like Northern Ireland, the Scottish Highlands and outlying Islands, Outer Hebrides, Channel Islands, Isle of Man, Scilly Isles, and other postcodes not considered as UK mainland can be obtained also by calling our offices.

Please note that the processing of a payment and acknowledgement email does not constitute a legally binding contact. In the case of mispricing, changes in stock quantity, or if we believe the machine will be misused, we reserve the right to cancel the order and provide a full refund.

Heavy Items

You will be contacted by phone after ordering a larger item to confirm a delivery date before your order is dispatched. Large or heavy items are dispatched through a pallet network, so if we can’t get in contact with you, we may be unable to send out your item on a next day delivery. Please be sure to include a working phone number with your order.

Heavy items will require the recipient to make arrangements to take delivery of the goods and may require the recipient to help the courier unload the item. For items that are delivered on a pallet the courier will leave the pallet as close to your door as possible.

1500rpm diesel generators will require forklift (or similar) offloading; if this is not available then we can arrange a Hiab offload at an additional price – please call us to discuss any delivery requirements.
