Features: Charging time: to charging 1000UF capacitance to 450V, it will take about 5 seconds Input: DC9-24V, Lowest starting voltages: 8.4V; Power: 40W continuously working, it can reach 70W occational working Output: Adjustable DC200V-450V (Most 450V the output voltages is stable even the input voltages is changing) Note:The use of low-voltages side of the current limiting mode, is to limit the low-side current, especially for the capacitor to charging, the capacitor before charging the voltages of 0, the direct charging, (this time is equivalent to short-circuit states) This version can be directly connecting to the following capacitor 1000UF charging, more than 1000UF, to a series of 5W, 10ohm cement resistance around what about. Not suitable for other power supply too much power, due to current limiting, the output in the overload when the output voltages will be pulled down. Will cause the phenomenon of unstable output voltages. Specifications: Component: ABS Size:Approx.85x50mm/3.35x1.97inch Input:9v-24v Output: Adjustable DC200V-450V 7A Package Includes: 1pc 9v-24V to DC200-450V boosting Power Module note: Please allow 1-2cm errors due to manual measurement. Please allow for slight color differences due to different display resolution.
