Description & Principle of Operation DeScRiPtion SEC-1223BBM-230 is a Switch Mode Power Supply (SMPS), which converts 230 VAC, 50/60 Hz to regulated 13.8VDC ± 0.2V at 23A continuous. It has additional provision for battery backup with charging in conjunction with external 12V Lead Acid Battery.
SeCtIOn 3 | Description & Principle of Operation PRinciPLe oF oPeRAtion Please refer to the Layout at fig. 2.1. The unit consists of 2 Sections - Switch Mode Power Supply (SMPS) Section and Battery Backup and Charging Section. The unit works as a DC Uninterruptible Power Source (DC UPS) in conjunction with an external 12V, Lead Acid backup battery.
SeCtIOn 3 | Description & Principle of Operation Switch for over temperature shut down will open and will activate over-temperature protection circuit to shut down the Power Supply Section. When the windings cool down to temperature ≤ 75°C ± 5°C / 167°f ± 9°f, the switch will close, shut down circuit will be de-activated and the output power from the Power Supply Section will be restored automatically.
SeCtIOn 4 | Protections Section will provide 25A and the battery will provide the balance 15A. The battery will start draining at 15A. The voltage at the Battery Terminals (5, 6) will start dropping and will be equal to the voltage corresponding to its actual State of Charge. The voltage at the Load Terminals (3, 4) will be around 0.3 ±...
SeCtIOn 4 | Protections windings cool down to temperature ≤ 75°C ± 5°C / 167°f ± 9°f, the Switch will close, shut down circuit will be de-activated and the Power Supply Section will be reset automati- cally. During the time the Power Supply Section is shut down due to over temperature, the backup battery will supply the load and will start discharging.

SeCtIOn 5 | Installation Load connection: The load is connected to the terminals marked “Load +” (4) and “Load - ” (3) through 32V, 25A fuse (f2) (See details below under heading “External fuses”). Please ensure that the polarity of the connection is correct - Positive of the load to the “Load +”...

SeCtIOn 5 | Installation resistance). Excessive voltage drop across the length of wires connecting the power source to the load produces excessive power loss and may also shut down the load due to under voltage created at the load end. Hence, the voltage drop should be kept to the minimum at around 2% by using thicker wires for longer distances.
SeCtIOn 6 | Operation Please refer to fig 2.1, page 5 - Layout & output Connections. cAUtion! If AC input power is not available and a battery has been connected for backup function, the load will be powered by the battery and the battery will continue to discharge as long as the load is in oN condition.

SeCtIOn 6 | Operation cHARGinG AnD BAcKUP oPeRAtion Charging current will be proportional to the discharged state of the battery and is lim- ited to maximum of 4A when the battery is completely discharged (Standing Voltage of 11.4V). The current will taper down from 4A as the battery gets charged and its voltage rises.
SeCtIOn 7 | limiting electro-Magnetic Interference (eMI) cAUtion! This unit generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communi- cations. However, this does not guarantee that interference will not occur in a particular in- stallation.

SeCtIOn 7 | limiting electro-Magnetic Interference (eMI) in the receiver may be caused by the antenna being too close. As with the transmitter related noise pick up, a loose coaxial connector or a broken or a missing ground may aggravate this problem. Normally, this noise will be below the background or “band” noise.

SeCtIOn 7 | limiting electro-Magnetic Interference (eMI) resistance is lower i.e. if the skin is wet or wounded. This leakage current does not return to the power source but is dissipated in Earth Ground. A leakage current of > 5mA could produce lethal electrical shock. Ground fault Circuit Interrupter (GfCI) is used for safety against electrical shock due to leakage.
