1. Functional Description
In the normal mode, the charger will charge the battery and supply constant power
for O/P. The charging current will reduce when loading current increases.
Sometimes if the peak load current is over the level that charger can supply, the
battery will supply the load current at the same time. When battery is fully charged,
the charger will maintain the trickle charging and the O/P current. In case of power
failure, the charger will stop providing current, and the battery will take over to
maintain the output voltage.
Charging & Power Device design
Zero interruption
On-line structure design to provide the constant power without interruption.
Utility power (normal mode)
backup mode (battery mode)
Soft start design to protect SPS
When AC is connect, SPS will turn on by soft start, then SPS in stable state,
It means if connect battery, there will be an inrush current to cause SPS, soft
start design will protect SPS.
Short circuit protection on outputs
The quick response short circuit protection limits the maximum output
current and prevents the fuse from burning.
Wide range input 130~280Vac, 50/60Hz
The UPS is able to provide stable DC output at 130~280Vac input voltage.
2~6 channels protection outputs
The multi-channel outputs use independent fuses for protection.
Condition monitoring – USB, RS232 & optional SNMP
The smart interface for monitor conditions of battery, utility power & load status.
Deep discharge protection
Battery hot-swappable (External battery type)

2. Installation Instructions
●
The DC UPS may only be installed by trained personnel or qualified engineers.
●
Connect DC UPS to the batteries with correct polarity.
●
Check all connections for correct polarity!
●
Upon starting up the DC UPS with system monitoring, an automatic self-test is
carried out. The function monitoring for the battery circuit is not active until the
first test cycle is done, approx. 1 minute after startup. A test cycle then takes
place every 32 minute.

Functional Description of System Monitoring
The I/PWR green LED lights up when AC I/P is good and charger can provide
current to the battery. In case of blackout or burning of I/P fuse, the I/PWR
yellow LED lights up, the Green LED goes out and the error will be reported
via the dry contact signal.
The O/PWR green LED lights up when the O/P power is normal, the O/PWR
yellow LED lights up when the O/P power is abnormal, or short circuit, or the
O/P is overload.
The CHG green LED lights up when the charging voltage on battery reach full
level, the CHG yellow LED lights up when the charger is full ON for providing
current to the load or battery. It is normal when CHG yellow LED lights up all the
time when the load level is over 60% of full load.
The BAT red LED lights up when the battery is not well connected or when any
one of the battery is fail, the BAT yellow LED lights up when the battery voltage
is low and the error will be reported via the dry contact signal.
