Description
Regulation is performed by a buck-boost transformer whose winding is switched by triacs under microprocessor control, with a response time of 2 ms. Suppression of impulse and high-frequency interference from the mains is added to this, so CR is appropriate where a stable voltage alone is not enough. Efficiency at full load is 95%, slightly lower than for the SE stabilizer because of the additional stages. The electronics monitor overload, as well as the minimum and maximum mains and output voltage. Single-phase models are designated CR-21…CR-34/1, three-phase CR-31…CR-54. The IP20 enclosure is installed in an electrical or server room.
How to choose
The boundary between SE and CR is set by mains quality: if the problem is only voltage deviations, SE with 98% efficiency is enough, while with interference from frequency converters and welding posts nearby CR is better. Power is taken with a margin over the total load; the single-phase range ends at 75 kVA, beyond that only three-phase units up to 2000 kVA. For one device up to 5 kVA there is the compact SH, and the conditioner does not protect against a complete mains loss, for which an online UPS is needed.

FAQ
How does a power conditioner differ from a voltage stabilizer?
A stabilizer only levels the voltage, while the CR conditioner also suppresses mains interference. Both units are built on a buck-boost transformer with triacs.
What is the power of CR power conditioners?
Single-phase CR-21…CR-34/1 have 1–75 kVA, three-phase CR-31…CR-54 up to 2000 kVA.
What protections does the CR conditioner have?
Overload protection and monitoring of the minimum and maximum voltage of both the mains and the output.
How fast does the CR power conditioner respond?
The response time is 2 ms, and efficiency at full load is 95%.
