INSTRUCTIONAL MANUAL :--( SA Model)
SMPS BASED INTEGRATED BATTERY CHARGER (AUTO FLOAT BOOST)
 Salient features / Description:The charger is housed in powder coated, rugged MS enclosure of 1.2mm
sheet. It is compact, light weight & portable with handle. Provision is made
for base & wall mounting. It can be used as table top model as well. There
is built in PFC in case of 1500W model to reduce power consumption &
increase efficiency. This reduces energy bills in long run. It employs latest
state- of- the- art SMPS technology with true CV-CC Characteristic for the
fast & precise charging. This ensures quick charging of battery without
getting under or over charged. This increases the battery life & reduces
battery maintenance cost. Input is protected against O/L & S/C by MCB.
Battery reverse polarity protection is given by MCB. Digital meters are used
to monitor battery status, both V & I. Auto /Man facility provided. Deeply
discharged battery also can be revived. Screw terminals of adequate size
are provided for making I/O connections. It can be used for any type of
battery ie, Ld-Acid, SMF, Ni-cd, etc. For application where LOAD &
BATTERY are connected in parallel, Separate LOAD & BATTERY terminals
provided. This ensures correct battery charging irrespective of load current.
 SPECIFICATIONS:* I/P: 180-270 VAC, 40-60 Hz, 1 PHASE, MCB protection.
* O/P: Suitable for charging 12V, 24V, 30V, 36V, 48V, 110V Battery of
different types VRLA, lead acid, Ni- Cd, SMF etc. (by selecting jumper).
* Charging Current: Settable by POT (50-100%).

* Charging Voltage: In AUTO mode Vflt = 2.25 Volt/cell
Vbst = 2.4 Volt/cell
Vt/u = 2.6 Volt/cell (only for Lead-Acid).
In MAN mode V = 2-2.5 Volt/cell, pot adjust.
* Noise & Ripple Less than 1%.
* Battery Reverse Polarity protection by Fuse & MCB.
* Metering: Both battery voltage & charging current indicated on
separate digital meters.
* AUTO & MAN mode selection by toggle switch.
* Protections –O/L, S/C, Reverse polarity by MCB, OVP & O/T etc.
* Forced Cooling by fan.
* Operating temperature: 0-450 C
* Optional : Load & Battery terminals separate.
In some cases when the charger is feeding load and simultaneously
charging battery, we are providing with the load & battery terminals separate for
the negative output. At output you will find load negative, battery negative and
common positive. Please connect the battery across positive & battery negative
and the load across positive & load negative.

Charging characteristics :-The charger uses latest state- of- the- art SMPS technology with
true CV-CC characteristic. It accepts wide input voltage variation without
changing charging characteristic. Low Ripple ensures better charging.
In manual mode single level CC- CV charging used. Battery can be charged in
either FLOAT OR BOOST mode. Battery Voltage & Charging Current can be set by
using POT provided on the panel.
In AUTO mode two level charging used to quickly charge the battery without
fear of getting it under/over charged. Charging current can be set by pot 50100%. Charging voltage levels are factory set by internal POTs.
Default Settings :
Float Voltage = 2.25 VPC
Boost Voltage = 2.4 VPC
Top-up Voltage = 2.6 VPC (Only for Ld-Acid).
Float to Boost change over current Ifb = 30% of Io set.
For SMF Battery Boost to Float change over current Ibf = 15% of Io set.
For Lead Acid Battery Boost to Float change over current Ibf = 15% of Io set.
Battery first kept on Float mode for the initial formation period, So that true
status of battery can be judged. After formation period, if battery draws more
than set Ifb current, then battery boost charged in CC till set Vbst reached. Then
cells are equalized in CV mode & current starts reducing.
For SMF Batt- When current reduces below Ibf, Batt is kept on Float mode &
charging cycle is completed.
For Lead-Acid Batt- When current reduces below Ibf, Batt is topped up in CC till
set Vt/u voltage reached, so that full capacity recovered without heating
electrolyte to get correct specific gravity, then Batt kept on Float mode &
charging cycle is completed.

OPERATING MANUAL :-MANUAL MODE:1. Keep Input & Output MCB’s OFF.
2. Connect input supply L N E & output to battery make sure that polarity is
correct (positive & negative terminal).
3. Keep toggle switch in Manual position.
4. Switch ON input power.
5. Switch ON BATTERY MCB.
6. Charging current can be set 50-100% by pot provided on the panel
depending upon battery capacity. Generally C/10 TO C/5 charging current used.
7. Battery can be charged in either FLOAT or BOOST mode. FLOAT or BOOST
voltage levels can be set using pots on panel.
AUTO MODE :1. Keep toggle switch in AUTO position.
2. Switch ON input power.
3. Switch ON BATTERY MCB.
For any specific application Float & Boost Voltages can be set by user by
selecting proper jumpers and adjusting respective trimpot inside.
For setting of Float voltage put the jumper in ‘F’ position & set the desired float
voltage on the voltmeter by using Float trimpot.
For setting of Boost voltage put the jumper in ‘B’ position & set the desired Boost
voltage on the voltmeter by Boost trimpot.
Once setting are done, donot forget to put jumper in original position.
