PSU-B-13,8V/L-3A/1/EL-TR-17Ah/MC AWZ 300 v.2.1 Linear, buffer type power supply. EN Release: 3 dated 18.04.2011 Supersedes the release: 2 dated 25.02.
Table of contents. 1. Technical description. 2. Installation. 3. Handling and operation. 4. Maintenance. 1. Technical description The buffer power pack is dedicated for uninterrupted power supply for the equipment requiring the stabilized voltage 12V DC (±15%). The linear stabilizing system applied in the equipment delivers the voltage with lower level of noise and shorter response time for the interference as is the case where a pulse stabilizer is applied.
Technical parameters 230V AC, 50 Hz (-15%/+10%) TR 80 VA *12.8 V ÷ +13.8 V DC Output voltage Uout 13.8 V DC – rated (13.4 V DC @ 3A ) Output current Iout Imax – 3A (const.) Power 42 W max I-st grade - 200% ÷ 250% of supply power – limitation of current and/or fuse failure in the battery circuit (fuse-element replacement required) SCP short-circuit protection II – nd.

Caution: Pay special attention when completing the shock protection circuit: the yellow-green PE protective conductor of the power supply cable must be connected from one side to the terminal in the power pack enclosure. The operation of the power pack without the shock designated protection circuit properly completed and technically operable IS NOT ADMISSIBLE! The operation without such circuit threatens with damage to the equipment or electric shock. 4. 5. 6. 7. 8.
3.2. Operation from the battery. Starting the operation from the battery. The time of operation with supplies from battery depends on the battery capacity, the extent of charging and the load current. For example, for the typical, fully charged battery with capacity of 17 Ah and load current 2A, the maximum operation time safe for the battery is approximately five hours. The battery should be connected in accordance with the designations [3]. Disconnection of the discharged battery.
WEEE MARK The waste electric and electronic products do not mix with general household waste. There are separate collection system for used electric and electronic products in accordance with legislation under the WEEE Directive and is effective only with EU. Notice: The power supply unit is adapted for cooperation with the sealed lead-acid battery (SLA). After the operation period it must not be thrown but recycled according to the applicable law.
