TWIN 40 charger

Dual Charger Graupner Ultra Twin 40 was designed with the aim to provide everything you need and recreation elektroletcům elektrojezdcům charging "under one roof" - and just two sets at once! It therefore contains switching power supply for mains operation 230 V / 50 Hz, but equally it can be powered from a 12V lead acid (car or traction lead-acid battery). Ultra Twin 40 lets you charge all common types of cells (NiCd, NiMH, Li-poly, Li-ion, Li-Fe gel), plus two channels are equipped with a built-in triple-channel balancers, which ensures very safe charging of lithium batteries.

• The input supply voltage of 11-15 V DC or mains voltage 230 V / 50 Hz
• To charge 4-8 NiCd / NiMH cells, 1-3 Li-ion / Li-poly / Li-Fe articles in both channels
• Optional charging current (0.8 A, 1.5 A, 3 A, 5 A) on both channels
• Max. power to charge 2 x 40 W
• End charging by regulators delta-peak for NiCd and NiMH batteries
• Lithium batteries are charged using the "constant current / constant voltage"
• Storage charging for lithium batteries
• Trickle charging for NiCd and NiMH batteries 50-250 mA
• Termination charge after the set time or supplied charge
• Two single-line LCD display with simple and clear menu and display parameters during charging
• The safe operation contributes a series of text messages alert - incorrect input voltage, bad wiring, inadequate or battery status, incorrect polarity on output
• Protection against reverse polarity and short circuit.
