Battery charger module (BCM)
The PCM works together with the existing battery charger sections of the installed Power modules. If BCMs are mounted
additionally has no effect to the existing charging system; only the cahrging current increase. Each BCM increase the
charging current of the system by 15A. The charging current of each BCM is 6 times of the cahrging caurrent of a Power
module.
Putting additional BCM inside the system will reduce the charging time for big battery capacities or make it simply pos-
sible to work together with big battery systems. Often an additional BCM is the only way to cahrge the battery system in
an optimal way. During mains available the charging current is taken additionally from the input mains at 230VAC single
phase. If the BCM is installed the slot correlation as follows: (left slot - Phase L1, middle slot - Phase L2, right slot - Phase
L3).
Any number of BCMs can be installed inside one UPS, minimum 1 Power module has to be installed inside the cabinet. A
front LED give inforations about the BCM status as well as trough the display of the UPS TRI POWER X33 MOD HP. The
module is controled by a microprocessor to verify correct power flow and relaibility. We recommend to use BCM with
battery capcities bigger 60Ah.
Input voltage 230Vac +15% -20%, Rated Power 4kW, Nominal charging current 15Adc (Maximum), Voltage at time fixed
float charge stage 13.75 Vdc/Battery block.
The multicolor LED on the front indicate easyly the status of the BCM. All fans are continously speed controlled; speed-
depending on charging power.
The intelligent 4-Phase charging cycle process optimise batteries livetime (Boost charge with constant current, finished
by charging with constant voltage, time limited float charge and Stand-by cycle).
Off-Line-Mode
UPS TRI POWER X33 MOD HP is designed to run in Off-Line-Mode. This is the most energy efficient mode with having the
connected load supplied during mains fault.
During Off-Line-Mode the load is directly supplied by the mains thrugh the automatic bypass section integrated in each
Power module if mains is availble).
in this case the output voltage and the frequency are depending on the mains which supplying the UPS TRI POWER X33
MOD HP. The UPS is not able to control or to filter the voltage to the load. The advantage is the higher efficency, because
the UPS is not working in line with the load and working without load.
In event the output voltage is outside ±15% of the rated voltage or the mains is not available the UPS transfer the load to
the inverter section and the load will be supplied from the batteries.
The autonomy time is depending by active power consumption of the load and the battery capacity.
If the mains is back inside limits the load will be transfered back to mains and the UPS change automatically back to Off--
Line-Mode.
In operation or in Service Mode it is possible to change between On-Line and Off-Line Mode any time.

To activate the Off-Line-Mode please follow Setup UPS -> Bypass -> Off-Line-Mode. Enable your choise by pressing
the ENTER key.

To activate the On-Line-Mode please follow Setup UPS -> Bypass -> On-Line-Mode. Enable your choise by pressing
the ENTER key.
ATTENTION
If the load supply should be absolutely uninterruptible with high quality on voltage and frequency the UPS TRI
POWER X33 MOD HP has to operate in On-Line-Mode double conversion.
