Graupner,ULTRA DUO PLUS 30englisch,6416.67

ULTRA DUO PLUS 30englisch Graupner 6416.67 Micro-processor controlled high-performance fast-charge, battery maintenance and balancing unit for NiCd / NiMH / Li-Io / LiMn cells and lead-acid batteries. Battery clips for connection to 12 V car battery; also integral high-quality G4 gold-contact connectors for connection to 230 V / 12 V mains PSU. High-performance high-tech battery charger exploiting the latest micro-computer technology - in a "shirt pocket format" case. Ultra-simple operation with clearly arranged program structure and 4-button terminal including user guidance and monitor dialogue. Two charge outputs for simultaneous charging of two fast-charge capable batteries with automatic "full" detection Battery 1 charge output: 1 - 30 NiCd or NiMH cells 1 - 10 Li-Io or LiMn cells 2 - 24 V lead-acid batteries Charge current 100 mA - 7 A Discharge current 100 mA - 5 A. Delta-Peak cut-off detector for accurate charge termination when full. Battery 2 charge output: 4 - 8 NiCd or NiMH cells Charge current 50 mA - 500 mA (50 mA step) Delta-peak cut-off detector for accurate charge termination when full. High-contrast two-line LCD screen for simultaneous display of all relevant parameters such as charge current, charge time, capacity, battery voltage etc. Very high efficiency voltage converter, pulse frequency over 40 kHz Delta-Peak cut-off detector for NiCd and NiMH cells, eparately variable sensitivity, ensuring full charge to 100% capacity Charging of single cells - ideal for glowplug energizer batteries and for selecting cells Capacity test programs with variable charge and discharge currents and selectable power-off voltage. Lead-acid battery charge programs with optimised charge characteristic curve, discharge facility, variable discharge current for determining battery capacity and residual capacity. Overcharge timer. Prevents premature termination after the start of a charge process, and allows controlled overcharging for maximum possible battery power. Deep discharge protection for car battery, selectable threshold. Fast charge safety timer prevents total overcharging and destruction of the battery if a pack contains defective cells. Buzzer setting. Audible Ready alert at end of charge program, variable; off, 10 sec., continuous Switchable button beep Power ON program Selectable charge program when car battery is initially connected.
