(g) P&P Modular design:
The power circuit is separated into several modules
plugged into slots in the UPS, which is easy to pull out, permit quick
maintenance and easier trouble shooting. Therefore, it can be regarded as plug
and play modules.
(h) Cold start function:
the UPS can be started without AC source, that is, can
be started with battery only, because current limit circuitry is added. It can
prevent the problem of many UPS that the big inrush current blow the battery
fuse and hurts the DC capacitors when battery is connected to empty DC bus
(before the DC bus is energized).
(i) Multi-CPU design:
Several CPUs are employed in the control circuit, critical
functions are designed to parallel redundancy to improve reliability. Therefore,
in case of one CPU fails the other CPUs keep on their duty and the output AC
will not be affected.
(j) Defense to mis-operation:
The UPS is designed with breaker on/off sensor,
power supply sensor etc. Therefore any operational mistake made by the user
causes no harm to the UPS.
(k) Wide input range:
The UPS is designed to accept extra wide input range, so
that it can work comfortable under poor AC source. Also, all the input
components used are especially selected to handle extreme high voltage and
high current.
(l) Tolerate harsh environment: Each component of the UPS is chosen with
larger safe margin to accept extreme environment, such as temperature, humidity,
attitude, shock or contamination.
(m) Intelligent charger:
The UPS will automatically recharge (boost charge) the
battery every time after the battery is consumed to a voltage 2V/Cell, so that the
battery can be recovered to the full capacity as soon as possible to be ready for
the next back-up. Besides, in order to keep the battery in the best condition, the
UPS will boost charge the battery for several hours (selectable) automatically
every month. To avoid over charging the battery, Boost charge will stop when
the ambient temperature is over 35
℃
(95
℉
).
