SECTION 1 | Safety Instructions 1.1 IMPORTANT SAFETY INSTRUCTIONS This manual contains important Safety and Operating Instructions. Please read before using this unit. 1.2 SAFETY SYMBOLS The following safety symbols will be used in this manual to highlight safety and information: WARNING! Indicates possibility of physical harm to the user in case of non- compliance. - Page 4 SECTION 1 | Safety Instructions d) To reduce the risk of electric shock, unplug the power supply from the outlet before attempting any maintenance or cleaning. Turning off controls will not reduce this risk. e) To reduce risk of damage to electric plug and cord, pull by plug rather than cord when disconnecting the unit.

Page 6: Description & Principle Of Operation
Description & Principle of Operation 3.1 DESCRIPTION SEC-1225G-BBM is a Switch Mode Power Supply (SMPS), which converts 115/230 VAC, 50/60 Hz to regulated 13.8 VDC at 25A continuous. It has additional provision for battery backup with charging in conjunction with external 12V Lead Acid Battery. - Page 7 SECTION 3 | Description & Principle of Operation • Protected against short circuit, overload, over voltage and over temperature • Cooling by temperature controlled fan improves efficiency and prolongs life of the fan • CE marked for safety and EMI / EMC compliance 3.3 PRINCIPLE OF OPERATION = 0.2 VDC 13.8 VDC...
- Page 8 SECTION 3 | Description & Principle of Operation 3.3.2.2 Regulated 14.0VDC from the SMPS Section (details at Section 3.3.1 above) is fed to the Battery Charging / Backup Section through Schottky Diode “D1” that provides isolation between the SMPS Section and the battery to prevent the battery from feeding back into the SMPS Section.
- Page 9 SECTION 3 | Description & Principle of Operation and at the same time, charging a typical 100 Ampere Hour (Ah) battery discharged to 11.1V (70% discharged at Discharge Rate of 23A i.e. at around 5 Hr Discharge Rate of C/5). When the battery is charged to Float Voltage of 13.5V± 0.2V, the charging current will reduce to a very low value of around 0.1% of its Ampere Hour (Ah) capacity to compensate for its self discharge.
- Page 10 SECTION 3 | Description & Principle of Operation 3.3.2.6.1 The voltage available at the Load Terminals (3,4 in Figs 2.1 and 3.1) during battery backup will be as per Equation 2 below: Voltage at Load Terminals Battery Voltage – Forward ...Equation 2 when battery is Voltage Drop across...

SECTION 4 | Protections 4.1 OVER LOAD / SHORT CIRCUIT CURRENT PROTECTIONS 4.1.1 Battery Backup Function is not Used - External Battery is not Connected and the Unit is Used as a Power Supply In this case, the entire load current will be supplied by the Power Supply Section and will be limited to a maximum of 27A by its Current Limit Circuitry. - Page 12 SECTION 4 | Protections In case of short circuit on the load side, the external 25A Fuse (F2) on the load side will blow because of very high additional current supplied by the battery (Additional battery current supplied into the short circuit on the load side = Short circuit current - 27A from the Power Supply Section).

SECTION 4 | Protections windings cool down to temperature ≤ 75°C ± 5°C, the switch will close, shut down circuit will be de-activated and the output power from the Power Supply Section will be restored automatically. 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. - Page 14 SECTION 5 | Installation Well ventilated: The unit is cooled by convection and by forced air-cooling by temperature controlled fan on the backside of the unit. The fan at the backside of the unit draws cool air from air intake openings on the sides and discharges hot air through the exhaust openings behind the fan.
- Page 15 SECTION 5 | Installation 5.4 MOUNTING ORIENTATION The unit has air intake openings on the sides and exhaust openings at the backside for the cooling fan. The unit should be mounted in such a manner so that small objects should not be able to fall easily into the unit from these openings and cause electrical / mechanical damage.
- Page 16 SECTION 5 | Installation 5.6.2 Pin Type of Terminal Lugs for Wiring to be Connected to DC Output Terminals: The DC output terminals have a tubular hole with a set screw (See Section 5.6.1 above for specifications). As the DC terminals have been provided with a set screw, do not connect bare stranded wire end directly to the DC output terminal as the strands will spread out when the set screw is tightened and all the strands may not be pinched firmly under the set screw.
- Page 17 SECTION 5 | Installation section produce higher resistance) and higher ambient temperature. Temperature rise higher than the temperature rating of conductor insulation will melt / burn the insulation resulting in possibility of electrical shock and fire. The National Electrical Code specifies maximum current flow (Ampacity) through a particular wire size [normally specified as cross-section in American Wire Gauge (AWG)] for a particular temperature rating of conductor insulation, ambient temperature and type of surrounding medium (like free air, raceway, etc.).

- Page 20 SECTION 6 | Operation Battery should not be charged at very high current. Normally, as a Rule of Thumb, the maximum charging current should be limited to 10% of the Ah capacity at 20 Hour Rate unless higher current is allowed by the manufacturer. Higher charging current produces higher heating, which reduces the life of the battery.

SECTION 7 | Limiting Electro-Magnetic Interference (EMI) CAUTION! Conducted and radiated noises in this unit are limited as per the applicable National / International Standards. In North America, the applicable standard is FCC Part 15(B) for Class “B” Digital Devices for Residential Installations. - Page 22 SECTION 7 | Limiting Electro-Magnetic Interference (EMI) 7.4 EXCESSIVE RF OUTPUT INTERFERENCE BY SMPS DUE TO INCOMING RF INTERFERENCE WHEN POWERING RADIO TX / RX SMPS are also recipients of radio interference. The normal operation of the power supply can be disturbed due to RF noise getting coupled into the power supply. Thus, the power supply may generate excessive RF noise and lose output voltage regulation due to excessive transmitter energy being coupled through the AC / DC lines to the power supply’s regulator feedback path.
- Page 23 SECTION 7 | Limiting Electro-Magnetic Interference (EMI) • Connect a ¼” wavelength of wire on the Negative terminal of the power supply. Connect one end of the wire to the Negative terminal and leave the other end free. The wavelength corresponds to the wavelength of the interfering frequency.
