Description
Regulation is electrodynamic: a servo motor moves the current collector along the winding and the output changes without steps. A 10 % grid deviation is corrected to 2.5 % in 0.6 s, which is enough for machine tools and instruments sensitive to slow fluctuations. The output accuracy is set at ±1 % and can be relaxed to ±5 % so that the mechanism responds less often to small fluctuations and lasts longer. The H series is designed for 220–240 V and the L series for 100–127 V. The enclosure is floor-standing, IP20, and is placed in a dry room next to the consumer. Efficiency is at least 98 % and the manufacturer's warranty is 3 years.
How to choose
The input range of ±15 % is narrow, so measure the voltage during peak-load hours before buying. If the dips are deeper, look at the static ESR with a range of up to ±50 % for 3–100 kVA. For an IT load of 2.1–14 kVA with a response within 200 ms there is the PWM.

FAQ
How fast does the mSVS+ respond to a voltage sag?
The stabiliser corrects a 10 % deviation to 2.5 % in 0.6 s. For fast dips static electronics are more suitable.
What grid deviation can the mSVS+ withstand?
The operating range is ±15 % of the nominal. This unit is not suitable for grids with deeper dips.
Can the stabilisation accuracy of the mSVS+ be changed?
Yes, the factory accuracy of ±1 % can be adjusted up to ±5 % if the load is not so sensitive.
What is the warranty on the mSVS+?
The manufacturer gives a 3-year warranty on mSVS+ series stabilisers, and the servo drive wears more slowly with a moderate accuracy setting.
For which grids are mSVS+ versions available?
The H version is intended for 220–240 V grids and the L version for 100–127 V grids of American and Japanese type.
