Introduction
OKY is leading EMI/EMC Filter developing company in Korea. We develop UDS to provide best solution for voltage sag and power Interruption. UDS is developed in the combination of DVC and UPS.
"Welcom to OKY LTD.
OKY is leading EMI/EMC Filter developing company in Korea.Since 1992, we are developing EMI/EMC filters and suppling them to our customers.
Also we developed power quality solutions, such as DVC (Dip-sag voltage compensator) and UPS.
Recently, we expanded our business field into new and renewable energe,smart-grid electric vehicle, We hope to see you soon.
We manufacture EMC/EMI products like D.C, A.C Single Phase, A.C 3Phase 4wire, Inverter Input, Inverter Output and power products like Single Phase DVC, Three Phase DVC, Automatic Transfer Switch, and
Sag is momentary voltage drop phenomenon within one second.
There are two causes why sag happen. First, natural reason such as lightning,
storms, snow, heavy winds, or damage by wild animal and plant. Secondly
artificial reason which is manly about input voltage drops by electrical overloading
due to peripheral equipment usage.
Sag(dip) of power supply can appear without pre-warning and usually last less than 0.4 seconds, and can dip
the supply voltage down by 90%. Sag issues is now the most frequent quality problem in electrical power distribution.
DVC
DVC is engineered to deliver power supply at constant voltage whenever
there is a voltage dips at the main line, even complete momentary power
interruption, for up to 5 seconds (1 sec at full load).
DVC will protect sensitive equipment from being tripped by short duration
of power supply quality problem. In short, DVC enhance operation reliability of the equipment and protect
precision equipment against such electrical problem without additional operational step to the end-users,
as it is completely maintenance free device. Also a lot of malfunction which happens in electronic components
and circuits could be prevented with DVC.
Benefits of DVC
• DVC is maintenance-free for its entire service life span of 10 years long.
• DVC operates at high energy efficiency of more than 98%.
• DVC is 100% solid-state design which means no moving parts (no cooling fan) embedded as well as no battery used.
• DVC is compact in size and very quiet in operation.
Energy Storage of DVC
EDLC(Electric Double Layer Capacitor)
ELDC, Supercapacitor is an electrochemical energy storage
device in the ""power"" industries Compared with battery,
supercapacitor has one-tenth of energy, but delivers over
10 times power due to ultra low ESR. It operates more reliably
in wider temperature and its life is semi-permanent,
over 500,000 cycles.
Features
Rated 2.5V & 2.7V & 3.0V
Higher Power Density(low ESR)
Over 500,000 cycle life (semi-permanent)
Short-term Peak Power assist applications
Operating temperature range :
- Rated 2.5V : -25? ~ 70?
- Rated 2.7V & 3.0V : -40? ~ 65?
Standards of power failure
Equipment with Semi 47 protection capability does not mean that they are power dip proof. In fact, they are only protected with shallower dip, from 20% to 50%, dependent on the dip duration. Whenever there is a power dip occurs in heavy industrial estates, chances are it will dip more and longer than Semi 47 standard and force your equipment to shut down. On the other hand, DVC offers far better than Semi 47 requirements. DVC protects well your equipment against all power dip, regardless the depth and duration of the voltage dip, just at a fraction of total equipment cost.
