The SMPS based CONVERTER should be based on High Frequency (20 KHz and above)
Switch Mode techniques.
Resettable Fuses shall be provided, wherever appropriate, to protect the module against failure
of control / sensing circuit.
The design shall have suitable time delay / hysteresis to avoid hunting during switching ON and
OFF of the system. The module shall disconnect at 150V and reconnect at 170V AC.
Switching ON and OFF the fan shall be temperature controlled. In case of fan failure the module
shall have automatic protection to switch off the module above 70 deg centigrade and restore
automatically with reduction in temperature. It shall not cause any fire hazard. The fan shall also
be protected against short circuit by providing a fuse.
The CONVERTER modules shall have forced cooling and only DC fan shall be used.

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 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%

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.
