Description
The output voltage is 210–240 V (L-N) or 364–416 V (L-L). The unit tolerates load unbalance of up to 100 %, so single-phase consumers spread unevenly across the phases do not push the voltage outside the ±0,5 % accuracy. Surge protection is built from class I and class II SPDs. The range includes versions E, I and EI with an emergency manual bypass, a disconnection bypass and an input breaker. Bypasses let the optimizer be serviced without leaving the load unpowered, and the input breaker isolates the unit from the mains.
How to choose
Pick the model by the total load in kVA within 100–3200 kVA. Then choose the version. E, I and EI differ in the set of bypasses and the input breaker, so the choice depends on whether the optimizer must be serviced without stopping the line. For loads up to 250 kVA there is the ESL-5, 45–250 kVA, with 200 % overload for 2 min, and if stabilization with reactive power compensation is needed, look at the Sirius advance, 60–4000 kVA, with ±0,5 % accuracy.

FAQ
What power range do the ESL-10 / ESL-20 cover?
The range is 100–3200 kVA. For smaller loads there is the ESL-5, 45–250 kVA.
What are the output voltage and accuracy of the optimizer?
The output is 210–240 V (L-N) or 364–416 V (L-L) with ±0,5 % accuracy.
Can the optimizer handle an unbalanced load?
Yes, load unbalance of up to 100 % is permitted.
What protective equipment does the optimizer include?
Class I and class II SPDs. Versions E, I and EI add an emergency manual bypass, a disconnection bypass and an input breaker.
Why would a plant need a voltage optimizer?
It reduces energy consumption and improves power quality at large industrial sites by keeping the voltage within the set limits.
