Description- Multiple Electrical Protections: Short circuit protection, reverse polarity protection, low voltage overcharge protection, overload overcharge protection- Good Heat Dissipation: The stable aluminum plate provides double reverse current protection and low heat generation. (All electronic components generate heat when operating, it is best to shade them for better heat dissipation, avoid direct sunlight or damp places)- Easy to Use: Equipped with a liquid crystal display, which can display the status and data, and can easily switch modes and parameter configuration.SpecificationsModel Number: JS-BOType: PWMApplication: Charger Controller, Solar Working Station, Lighting Controller, Voltage Controller, Solar System ControllerWork Time (h):24HMax PV Power:3000WMax PV Voltage:50VCertificate:ROHS,CE,ISO9001,ISO14001Battery type:Lead-acid battery /BAT/ B1 and Ternary lithium battery /LIT1/b02Battery type 2:Lithium iron phosphate battery /LIT2/ b03Size:133x70x35mm/5.2x2.8x1.4inProtection Function:Overcharge/ Overdischarge/ Overload/ Shortcircuit ProtectionCharge way: Charge Under Sun power solar panelsUSB output:2 USB-5V/2A MAXOperating temperature:-35~+60℃Waterproof level: IP32LVD:10.7V/21.4V/42.8VLVR:12.6V/25.2V/50.4VRateddischarge current: 10A/20A/30A optionalUSB output voltage: 5VBattery voltage: 12V/24V automatically selectable.Battery type: lead-acid battery, lithium iron phosphate battery, lithium battery.Packing list1 x Solar Charge Controller1 x Instruction
