The NAL24V intelligent modules are power supply units and battery chargers in one. In conjunction with an appropriate battery pack, the NAL24V is ideal for use as a UPS in the control cabinet. They are controlled by a microprocessor and optimize the charging and discharging of the battery while ensuring a long service life. Continuous monitoring of the battery efficiency reduces the risk of damage to the battery and ensures safe operation even with continuous charging. The NAL24V is suitable for different battery types and can be used for two different charging modes.
