SMPS Battery Charger
High-frequency switching, modular construction, hot-swappable rectifier modules. Roughly a third the footprint of an equivalent thyristor charger and around 92% efficient, with a controller that manages float, boost and battery health without intervention.
View specs 5 A – 200 AFloat Cum Boost Charger
Thyristor-controlled, transformer-isolated, built for substation duty. Heavier and less efficient than SMPS, and far more tolerant of dust, heat and a rough supply. Specified where the charger has to keep working for twenty years with basic maintenance.
View specsAnd when it’s the right answer
A battery bank is only as reliable as the charger holding it. Undercharge and the bank sulphates; overcharge and it gases, dries out and dies early. A proper industrial charger holds float voltage against temperature, steps to boost when the bank has been discharged, and steps back automatically instead of waiting for someone to remember.
We build both architectures. Thyristor-based float-cum-boost chargers where robustness and repairability in a substation environment matter more than efficiency, and SMPS chargers where footprint, efficiency and hot-swappable modular redundancy matter more.
Every charger is quoted against the bank: chemistry, cell count, Ah, ambient temperature and the discharge duty. Send us those five numbers and the quote will be right the first time. Where the same bank also has to feed AC control loads, quote the industrial inverter with it — charger, bank and inverter designed as one system rather than three separate assumptions.
A UPS charger is sized for its own bank on a standby duty. A cycling bank, a DG starting bank or a substation control bank needs a dedicated charger with proper boost control.
A rectifier makes DC. A charger manages a chemistry — temperature compensation, boost timing, deep-discharge recovery and end-of-charge detection.

Sectors that buy this
Telecom & Networks
Telecom runs on −48 V DC and on sites nobody visits. Modular redundancy and remote telemetry are the whole specification.
Data Centres & Server Rooms
Redundancy topology, battery runtime to DG pickup, and heat rejection. At this scale the UPS is the easy part of the specification.
Pharmaceutical & Life Sciences
In a GMP environment a power event is not only a downtime cost — it is a deviation, an investigation and potentially a lost batch.
Industrial Battery Charger — questions we get asked
Anything not covered here, call us — most of it is faster to answer on the phone.
What is a float-cum-boost charger?
It runs in two modes. Float holds the bank at a maintenance voltage indefinitely, replacing self-discharge without gassing. Boost applies a higher voltage to recharge a discharged bank quickly, then drops back to float automatically once the charge current tapers. Doing it manually is how banks get ruined.
SMPS charger or thyristor charger — which should we specify?
SMPS if you want efficiency, a small footprint and hot-swap N+1 redundancy, and you have a reasonably clean environment. Thyristor if the charger is going into a dusty substation where it needs to be repairable by a local technician with a multimeter twenty years from now. Both are legitimate; they optimise for different things.
How do I size the charger for my battery bank?
The rule of thumb is 10–15% of the bank Ah as the charging current, plus the continuous DC load the bank is feeding. A 200 Ah bank with a 15 A standing load wants roughly 20–30 A of charging plus the 15 A, so a 50 A charger. Tell us the bank and the load and we will confirm it.
Where we supply and attend
Industrial Battery Charger units are built at our Pune works and delivered, installed and commissioned across the city and the industrial belt around it.
Outside these areas we contract individually against distance, and we will tell you honestly if the response time you need is not one we can hold to. All areas served
