1 kVA and 2 kVA Electronic Voltage Stabiliser
The REOTRON MEK 7711 provides a stabilised voltage within ± 6 % of nominal for a wide range of different supply voltages. It is possible to accommodate a variation on the supply of up to ± 25 %. The unit is delivered with plug-connectors fitted and is ready to operate with the equipment that requires a stable supply.
The output voltage is adjusted in 6 steps so that the input voltage range of 75% to 125% is stabilised to 94% to 106% of the effective 230V output. This is achieved by using an auto-transformer with a primary winding that has multi-tappings which correspond to different supply voltages. On the secondary side there are a further six tappings, which are connected to the output circuit through solid state switches (triacs). A microprocessor controller determines the appropriate tapping, depending to the input voltage level. In this way a constant output voltage is maintained.
Externally, a row of LED’s are used to indicate whether the voltage is outside the allowable limits and which tapping has been selected. A soft-start prevents false tripping when the unit is powered-up.
Surge suppression is available as an optional extra.
