DC Output Characteristics
The module shall be capable of operating in "Auto Float cum-Boost charger" mode. It shall be programmed to operate as a float rectifier or a Boost charger depending on the condition of the battery
Auto Float Mode
Float voltage of each rectifier module shall be set as given below: Normal Float & Boost voltage for VRLA battery is 2.25V and 2.3V/Cell respectively. For conventional battery it shall be 2.15V and 2.42V/cell, respectively. For 110V/20Amp charger 55cells of 2V each will be used and for 48V/25A charger 24 cells of 2V each will be used. The module should have a range from 2.0 - 2.3V/cell in float mode & 2.2 - 2.5V/cell in boost mode to meet the requirement of VRLA as well as conventional batteries. The DC output voltage shall be maintained within ± 1% of the half load pre-set voltage in the range 25% load to full load when measured at the output terminals over the full specified input range.
Auto Boost Charge Mode
In auto boost charge mode, CONVERTER shall supply battery and equipment current till terminal voltage reaches 2.3V (VRLA battery) /2.42V (Low Maintenance battery) per cell.and shall change over to Auto Float mode after a defined delay of 0, 1, 2, 4 hours adjustable, to be set as per battery manufacturer's specification.
Efficiency The efficiency and Power factor of the CONVERTER in auto float and auto boost mode shall be as follows: Nominal input - 150-275V Output - Full Load, Efficiency > 90% and Power factor >0.95 to unity And for Nominal input - 150-275V Output - 25% to 100%, Efficiency > 85% and Power factor >0.9 Note: Active power factor correction circuit shall be adopted.
Total Harmonic Distortion The total line harmonic voltage distortion shall not be more than 10%. The total current harmonic distortion contributed by CONVERTER at the input shall not exceed 10% for all input condition and load 50% to 100% of the rated capacity.
Soft Start Feature
Slow start circuitry shall be employed such that CONVERTER module output voltage shall reach
its nominal value slowly within 10 to 20 seconds, eliminating all starting surges.
The maximum instantaneous current during start up shall not exceed the peak value of the
rectifier-input current at full load at the lowest input voltage specified.
Voltage Overshoot/Undershoot (with battery disconnected)
The CONVERTER modules shall be designed to minimize output voltage overshoot /
undershoot such that when they are switched ON, the DC output voltage shall be limited to ± 5%
of the set voltage and return to its steady state within 20 millisecond for any load of 25% to
100%.
The DC output voltage overshoot for a step change in AC mains from 150V to 275V shall not
cause shut down of CONVERTER module and the voltage overshoot shall be limited to ±5% of
its set voltage and return to steady state within 20ms.
The modules shall be designed such that a step load change of 25% to 100% or vice- versa
shall not result in DC output voltage overshoot/undershoot of not more than ±5% of the set value
and return to steady state value within 10 millisecond without resulting the unit to trip.
Parallel Operation
The CONVERTER modules shall be suitable for operating in parallel on active load sharing
basis with one or more modules of same type, make and rating.
The current sharing shall be within ± 10% of the individual capacity of each CONVERTER in the
system when loaded between 50 to 100% of its rated capacity.
Alarms & Indication of CONVERTER The following indications, controls & measuring points shall be provided on the front panel of CONVERTER
a) CONVERTER on Auto Float mode FLOAT Green b) CONVERTER on Boost Charge mode BOOST Green c) Mains available MAINS Amber
Alarm Indication with LED: a) Rectifier module over voltage OVER VOLTAGE Red b) Rectifier module under-voltage UNDER VOLTAGE Red c) DC output fail OUTPUT FAIL Red d) CONVERTER Overload/ short circuit OVERLOAD/ SHORT CIRCUIT Red e) Fan fail FAN FAIL Red Note: "Provision shall be made for stopping the audio alarm with a non-locking push button. a) Float voltage adjustment (float) b) Boost voltage adjustment (boost) c) Overload current setting (OL) d) Voltage monitoring point suitable for measurement by standard multimeter.
