Battery Chargers
Company: South Eastern Equipment Company
A range of battery chargers in capacities varying from 1 kVA to 300 kVA 12 V to 220 V DC is offered by South Eastern Equipment Co (SEECO), a manufacturer of transformers and voltage stabilisers. When a customer needs an uninterruptible DC power supply, a rectifier system in combination with battery is used. These systems can be either a single charger or a parallel redundant type to ensure uninterrupted DC supply. The alarm functions of these battery chargers are as follows: high voltage, low voltage, regular failure, ground (+) fault, ground (-) fault, single phasing, rectifier failure (each diode or SCR), fan failure (in forced cooling system) and line failure. Technical specifications: the input is a 3-phase 415 V, SOc/s 4-wire system with 10% variation or 1 phase 230 V 50c/s. The output has the voltage capacity of 12 V, 24 V, 48 V, 110 V, 220 V DC or any other desired voltages (settable at any volts and desired currents as per battery manufacturer's specifications). The system's capacity ranges from 1 kW to 300 kW both in single and three phase. It has a SCR control/ Dimmerstat control/Transductor control/Manual tap switch control. Its stability is 1% of the rated voltage on load varying from 10 to 100%. The current limit can be adjusted from 10% to 100% and the ripple ranges from 1% to 2% depending on the requirement. For DOT, the ripple will be 1 mV at 800 Hz for 24 V and 3 mV at 800 Hz for 60 V. Ambient temperature: the units can be operated without restriction over the range 0°C to +45°C and the load must be reduced for continuous operation at higher temperatures. The system has the humidity class from F to DIN 40040. The protection class ranges from IP20 to IP42. The system is moisture protected and has redundant chargers.
