Intelligent Battery Chargers


24 Volt 30 Amp Intelligent Battery Charger

The DSE9474 is an intelligent 24-volt, 30 amp CAN enabled switch-mode battery charger that can be programmed for different charging curves. This helps to maximise battery life. The charger is programmed using the DSE Configuration Suite Software. The charger can be DIN rail or chassis mounted and has three built-in LEDs to indicate current charging status and fault conditions. The charger continues to operate during cranking and running and accepts multiple AC voltage connections. 

240 mm x 263 mm x 89 mm (9.4” x 10.4” x 3.5”)
9474-01 - 24 volt 30 amp Intelligent Battery Charger (90-305v 50/60Hz)
