The SR series inverter is designed to convert 24V or 48V DC power to a continuous AC output for telecom, IT and industrial applications. It is 1U high and is supplied with mounting brackets for fitting into a 19in rack if required. The SR inverter includes a powerful digital signal processor with intelligent control software that allows easy programming of the main parameters via the front-panel keypad and LCD display; this can also be done remotely via RS-232.

The DC-AC inverter system is designed with advanced microprocessor technology and power electronics. The inverter features IGBT technology which, minimises size and weight, while enhancing output short circuit reliability and overload capacity.

The SR Series Inverters are designed to operate in one of two user selectable modes:

  1. Off-line/bypass mode: AC power is supplied from the incoming AC supply in normal operation with the inverter taking over in the event of a failure of the incoming AC supply.
  2. On-line mode: AC Output power is always supplied from the incoming DC supply. In the event of an incoming DC failure AC power will be supplied in bypass mode (if available).

In both cases, operation will revert to default once the incoming supply has been restored.  Operation with the AC source is synchronised at all times allowing the transfer to be interruption-free for sensitive equipment.

The inverter is equipped with a self-diagnostic microprocessor that is able to identify and show all failure messages on the LED/LCD display, with associated visual/audio alarms. The fan is fully monitored; any air flow restriction or fan failure will result in an alarm.

By combining the SR inverter with a suitable battery charger a fully backed system can be created.

At Relec Electronics the philosophy is to help design engineers build better solutions.

At Relec Electronics the philosophy is to help design engineers build better solutions.

We are proud to have one of the most comprehensive power supply ranges available, for both DC to DC and AC to DC applications. In addition, we offer a range of complementing products including EMC filters, switches and displays. Our aim is to build partnerships with customers and suppliers to both understand their requirements and to ensure a reliable supply of robust, yet technically advanced components that can be relied upon in the long term.

Power supplies, circuit protection and interface products form the backbone of our business. We work very hard to bring high-quality competitive products to the market, and our customers can be assured that any product we are promoting will not have reached them without full dialogue with the supplier together with a personal factory audit.

We believe the future is to offer our clients more choice thereby ‘adding value’ to their projects. This is achieved by offering custom products in all the lines we supply and by offering manufacturing services such as sub-assemblies and finished products. In our UK warehouse, we hold significant stocks of both standard and customer-specific parts and offer all the commercial services you would expect, including JIT, KANBAN, and specialist agreements tailored to suit individual customer needs.

Relec’s sales and technical support personnel, including our QA department, are all qualified engineers and are committed to ensuring that all aspects of our service meet and exceed today’s high expectations. We pride ourselves on providing extensive technical support for design engineers and full commercial support for our customers. By working with a limited number of manufacturers, who are leaders in their various technologies, Relec can provide the best solutions available.
