frequent converter mode (cf)
operating mode of the UPS as a frequency converter. in this mode, the static
bypass is disabled by the condition of disparate input and output frequencies.
Even if the LCd monitor shows a messages, it does not mean that the inverter
is operational. it is switched on by pressing the ‘oN’ button on the control
panel, see chapter 7.
4.4 SPECifiC fEATURES
•
True online with double-conversion technology and output frequency
separate from the mains.
•
output power factor 1. Pure sine waveform, suitable for almost all kinds of
loads.
•
input power factor > 0.99 and high overall performance (between 0,89 and
0,91 for models up to 3 kVA models and > 0,93 for higher power ratings).
Greater energy savings and lower user installation costs (wiring) are achived,
as well as low distortion of the input current, which reduces pollution in the
power supply network.
•
Great adaptability to the worst conditions of the mains. wide input voltage,
frequency and waveform ranges, thus avoiding excessive dependence on
limited battery power.
•
Possibility of fast and easy backup extension by adding modules in rack
format. Each battery module has two connectors for easy connection to the
device and other identical modules.
• N+X redundant parallel connection to increase reliability and flexibility in
power models > 3 kVA, with a maximum of 3 devices in parallel.
•
Selectable high-performance mode (ECo ModE) > 0,95 to 0,99 depending on
the model. financial savings for the users are possible.
•
it is possible to start the device without mains power supply or discharged
battery. be careful with this aspect because the greater the batteries are
discharged, the more the backup will be reduced.
•
intelligent battery management technology is very useful for extending the
lifespan of the accumulators and optimising the recharge times.
•
Standard communication options via the RS232 serial port or USb port.
•
digital input for Start/Stop of the device and ‘Error or fault’ digital output in
models with power ratings > 3 kVA.
•
Remote emergency power off control (EPo).
•
Control panel with LCd monitor available on all models and LEd indicators on
devices with power ratings > 3 kVA.
•
Availability of optional connectable cards to improve the communication
capabilities.
•
The device can be installed as a tower or rack using the attached supplies. The
control panel can be rotated.
