Detecting voltage change as device that supply
voltage that is fixed to subordinate device sensign
this automatically in case of input voltage is
changed or fluctuation occurs by subordinate device
through digital logic circuit, doing change trans
tap by electron switch, and it is the idealest
Electtronic Tap Changing Regulator method that
supply the fastest reaction rate and output voltage
that side effect does not exist.
Electronic semicconductor
control system
Verity protection circuit adapted, provided
against impulse noise and high reliablility
Fast reaction time 0.008 -
0.048 Sec at voltage change
Maintenance free and long life time
Pure sine wave that wave distortion
factor maximum 0.2%
Low noise, heat and very high
efficiency
Compact and light weight design
No switching noise by Zero
X-ing switching circuit
POWER FAILURE
- State that power turns off,
in other words, speak Zero-Volt.
- When switch cut-off in box that electricity does
control or there is singularity.
- When switch of input power was cut.
VOLTAGE SPIKES
- Present state that happen
because biographical hash noise or high frequency
voltage in normal rural districts is overlaped each
orther
- Occurance in device (welding machine, elevator,
MOTOR control board... And so on) had linked to uniformity
track.
SAGS
- Phenomenon that voltage sags in normal power stats
for given cycle.
- Starting current with run idle show is outbreak
in big idle show device.
SURGE
- Phenomenon that voltage rises temporarity in normal
power state for given cycle.
- Idle show decreases rapidly in box that electricity
does control or development in lightning strike ratten.
NOIS
- Phenomenon that check transmission of information
by noise or disrupts.
