SANYO DENKI Develops SANUPS C23A CE Marking Compliant Voltage Dip Compensator

February 12, 2020

SANYO DENKI CO., LTD. has developed and released CE marking compliant models of the SANUPS C23A voltage dip compensator that allow no interruption. The C23A will stably compensate for voltage dips or momentary outages. Factory productivity and equipment reliability can be increased in Asian and European countries where CE marking is required.

200 kVA


1. No Interruption

Even in the event of voltage dips or momentary outages, the C23A continues to supply pure sinusoidal power without interruption.
This prevents equipment susceptible to voltage dips from stopping due to failure or malfunction, improving the productivity of factory facilities.

2. High Efficiency

The C23A uses a parallel processing topology to achieve a 97% efficiency.(1)
This reduces running costs and contributes to environmental preservation.

3. Active Filter Function

An active filter cancels the harmonics generated by equipment; the corrected current waveform is harmless to the power grid and other equipment.
At the same time, the power factor is corrected to approximately 1.0, eliminating wasted power consumption.

4. Reduced Maintenance Costs

A long-life electric double-layer capacitor (EDLC) is used instead of lead-acid batteries, reducing maintenance labor and costs.

5. CE Marking Compliant

These models are compliant with the Low Voltage Directive, EMC Directive, and the amended RoHS (RoHS2) Directive, and therefore can be used in Asian and European countries where CE marking is required.

(1) For 100 and 200 kVA models.
