SCR Charger
The charger is designed to charge the battery at a constant value regardless of changes in the AC power voltage or the discharge state of the battery so that the battery is not damaged by overcharging or overdischarging. In addition, the charger load is always supplied with a constant DC power supply, so that in the event of a commercial power outage, DC power is supplied from the storage battery to the load without an instantaneous power outage.
Features
Excellent voltage stability
– The output voltage is extremely stable , so if the input voltage is within ±10% and the load is between 20% and 100%, the DC output is kept within ±0.5% when the input voltage is within a constant load within 1%.
Easy to handle
– parts are well positioned and modular assembly facilitates handling of maintenance and operation etc.
Output voltage setting
– Floating and equal charging voltages are adjusted separately and the selection of floating and equal charging methods is performed by the selection switch.
Protection
– The rectifier for the charger provides overvoltage protection and overcurrent protection, and the limit for overcurrent is set by the factory to approximately 125% of the rated output current.
