These component-level power supplies are intended exclusively for installation within other equipment by an industrial assembly operation or by professional installers. These are Class 1 power supplies; the unit must be properly connected to earth ground in end-use. A component power supply should be installed in end-use equipment according to the requirements of the safety standard used for that equipment. This power supply is not designed to be operated outside of an enclosure which provides a means of mechanical, electrical, and fire protection.


The Power Supply must be properly grounded to mains protective earth termination at end-use.


TRANSPORTATION & STORAGE: Ambient Temperature Range -40 °C to +85 °C Relative Humidity Range: 5% to 95% RH Non-Condensing Altitude: to 12192 m (40 000 feet) ASL OPERATION: Ambient Temp. Range -25°C to +55°C (at 100% load), to +70°C (at 75% load) Relative Humidity Range: 10% to 90% RH Non-Condensing Altitude (ASL): to 2500 m full power, to 3048 m (10 000 feet) derating 90% of full power


Recommended power wires dimensions you can find in charts below. The mate parts of connectors are also described below. For the air inlet and outlet there is required to maintain a minimum open space 10 cm. For chassis fastening you will need 6x screws M8. The preferred mounting position is vertical, with connectors on top. The input shall be fused by: Breaker ABB, S203MT, C16, or similar. The output Battery must be protected by following fusing: Breaker ABB, S802S-UCB125 (125A, char. B), or similar. Software: In case the standard units are delivered to the customer with the Configuration file (.csv) in default (factory) settings, it is necessary for the customer to upgrade the Configuration file (by the help of GUI) to the version, which corresponds with their specific project. The same needs to be done if the units are returned from the repair (RMA), since the units are shipped back to the customer with default Configuration setting.


  1.  The equipment is for business use (Class A). In a domestic environment, this product may cause radio interference in which case the user may be required to take adequate measures.
  2.  The AC Leakage current exceeds 3.5 mA at maximal input voltage and frequency (3 x 528 VAC / 63 Hz). It is necessary to take appropriate measures (additional fixed grounding of the chassis).
  3.  Do not touch the Output connector X2 during the operation. There is a hazard voltage present, up to 138 Vdc.
  4.  Caution, this is a heavyweight unit, 24-30 kg.


Switch off the input power and disconnect the battery (X2) together with connectors X3, X1, and wait for min. 2 minutes before doing any maintenance on the unit!


In case of failure, the unit must be returned to the Bel Power Solutions Authorized Service Center. There are no user-serviceable parts inside, except of the fan replacement. In case of failure of the fan this can be replaced without the whole chassis opening. The procedure is described below.


The unit outside is protected by painting with Soprano 1 – Art. 095 000298-000. Inside all PC boards are protected by lacquering with Humiseal 1B73.


Bel Power Solutions warrants each power supply of its manufacturer for a period of two years from the date of original shipment. This warranty applies to defects in materials and workmanship that result in non-performance to published specifications. The product(s) must be returned to a Bel Power Solutions Authorized Service Center for repair with a Bel Power Solutions pre-assigned RMA number. Bel Power Solutions assumes no liabilities for consequential damages of any kind through the use or misuse of its products by any user. No other obligations are expressed or implied. Please note that the specifications, terms, and conditions stated are subject to change without notice.


In case of fan failure any of four (three at LBC8000) fans placed on the front panel, can be replaced.

  1.  Turn-off the whole device and by screwdriver PH2 simply remove four outer screws (signed by red circle – not those holding the ventilation grill) on the front panel, which contains the failed fan and pull the panel out from the chassis (see Fig. 1).
  2.  Disconnect the fan connector from the PC board by pressing the connector latch.
  3.  Now by the same screwdriver remove four screws holding the grill together with fan on the panel.
  4.  Replace the part for an original replacement part YVD.00969 (the left end panel) or YVD.00946.0 (the rest panels). Contact our Service Center.
  5.  Keep the airflow direction from outside to inside. Proceed with the mounting in reverse order.

Life expectance: 70 000 / 50 000 hours (YVD.00969 / YVD.00946.0) @ 40 °C, continuous operationbel LBC800-1110SxxxG Battrey Charger User Manual  & troubleshooting 3

First turn on the battery breaker and only then turn on the input AC voltage breaker. The charger will start to supply the load connected at the Consumer output (Safe mode – constant voltage, e.g. 105 Vdc, the voltage depends on the LBC model). Inside, in series with this output, is connected an OR-ing diode, so two or more LBC systems (preferably each one with his own separate battery) can be at the Consumer outputs connected in parallel, to supply the load in redundancy. 30 seconds after the start-up the charger will perform the battery test by decreasing the output voltage. During battery test the output voltage can drop down to 80 V, if the battery is not connected. In this case, after the test the charger will be set to the Safe mode. In the other case (battery OK), or if the battery will be connected afterward, the charger will start to work in a current model and the voltage will be set to keep the maximal charging current, value corresponds to the measured battery temperature. The actual state can be seen by LED-s on the upper front panel (control unit) or by communication SW / GUI. When no temperature sensor will be connected to the X3 connector or any other fail will be detected, the charger will remain to work in the Safe mode (in this case the battery will be not fully charged). In this mode the output voltage is set below the value allowed at Tmax (charging curve dependent, e.g. 105Vdc). The Safe mode is indicated by the LED, see Datasheet BCD.00821 for details. When no battery voltage sense will be connected to the X3 connector, the charger will still work normally, only the battery voltage symmetry will be not evaluated and reported by communication. The charger does not have the possibility to disconnect the battery by Undervoltage, when supplied from battery only. UVLO must be controlled by consumers (typical turn-off should be less than 80 V, value depends on battery type).

This equipment complies with IEC 61000-3-12 provided that the short-circuit power Ssc is greater than or equal to 2,9×106 at the interface point between the user’s supply and the public system. It is the responsibility of the installer or user of the equipment to ensure, by consultation with the distribution network operator if necessary, that the equipment is connected only to a supply with a short-circuit power Ssc greater than or equal to 2,9×106.bel LBC800-1110SxxxG Battrey Charger User Manual  & troubleshooting 4
