REO has launched a new range of switch-mode, infinitely variable output, DC power supplies, which have been designed for industrial applications such as electroplating, cathodic-protection, electro-chlorination, vacuum-coating or for product testing. The largest unit in the range runs off a 3-phase 400V supply and produces 0_24 Vdc x 0_200A. The range can be extended to give a higher output voltage or current by using several units together, connected in series or parallel.

The output ripple is +/- 200 mV and the power factor 0.95.

There are two set point inputs provided and these can be used to give voltage, current or power regulation from external analogue signals or potentiometers.

Alternatively, internal, fixed set points can be entered through a touch panel.

The 5-digit display is used to indicate the operating mode and fault diagnostics, when these occur.

In addition, there is a fault relay with change-over contacts and a digital-enable input for interfacing the power supply with other equipment.

The standard unit fits into a 19' racking system and has a digital touch panel with an integral LED display that are used for setting up the operating parameters.

The overall dimensions are 177mm high x 428mm wide x 465mm front to back.

All connections are made through multi-way connectors and bus-bars in the front panel.

Switch-mode power supplies in this series, with low and medium current ratings, are also available.
