Votronic SR 140 Duo Digital Solar Load Controller

Solar controller for mobile homes and caravans.The solar controller is specially designed for use in mobile homes and caravans and is suitable for all types and brands of lead batteries (acid, GEL/dryfit, AGM/vellón and LiFePO4 batteries).
Batteries are optimally charged with IU1oU2 features through intelligent microprocessor control.The solar controller operates fully automatically and does not require maintenance and offers the following functions:

Details
SR 300-24

• Battery charge output card I, depending on the type of battery (plome or LiFePO4) 3 or 5 charging programs.
• Battery charge output of starter II: Separate auxiliary charge output with reduced charge current (12 V / 0.8 A or 1.5 A) for the support charge and the slow charge of the vehicle starter battery with overload protection for long inactivity periods.
• The load voltage does not have peaks and is regulated in such a way that the batteries do not overload.
• Two battery charge outputs: Automatic charge of the main or aboard battery (plate I).Supports charge and slow charge of the vehicle starter battery (Start II) with overload protection.
• Load without supervision: Standard protection against reverse discharge of the battery (when solar production is too low, for example, at nightfall, etc.), against overload and overheating.
• Buffer mode: Compliance with the charging features even when operated with consumers on the battery at the same time.
• Overload protection: regulates the battery charge current when there is too much solar power and the battery is full, ensures that the battery is as charged as possible when power is consumed by immediate recharge.
• Charge Characteristic "IU1oU2": the defined increase in the load voltage (U1) prevents the stratification of harmful acids and guarantees the compensation charge of the individual cells of the battery, followed by an automatic slow load (U2).
• Network filter on board: Integrated, allows the controller to operate in parallel with other charging sources, wind and gasoline generators, network chargers, alternators, etc. in a battery without any problems.
• Connection for temperature sensor: Automatic adjustment of charge voltage to battery temperature.In the cold, the weaker battery is charged completely better and the unnecessary gasification of the battery is avoided at summer temperatures.
• Very recommended if the battery is exposed to strong temperature fluctuations, p.B. in the engine compartment.
• Load cable compensation: The voltage loss on the load cables is automatically corrected.
• Ready to plug for connection of the Votronic LCD-Solar Computer S solar display devices for optimal system control.

SR 140 / 220 / 330 / 530 as SR 300-24 but with the following additional features

• Departure of measure for EBL (electric block of the vehicle): Allows the convenient use of the current screen (solar) integrated into the electric block to control the solar system.Be sure to check in advance the compatibility of your Schaudt Electroblock (EBL) and the corresponding control and display panel, as we cannot assume any responsibility for it.
• Output of switching "AES" (only SR 330-Duo Dig. and SR 530-Duo Dig.): If there is much excess of solar energy, it makes the ELECTROLUX/DOMETIC refrigerators automatically switch from gas to "AES" (Automatic Energy Selector) Operation 12 V.

loaders

• 1 "Gel": Gel Battery Charge Program, IU1oU2 feature: Adapted to gel/dryfit batteries sealed, gas hermetic with fixed electrolyte, which usually require a higher level of load voltage and longer U1 waiting times to achieve short load times with particularly high capacity storage and avoid the depletion of the battery in the long term.
• 2 "AGM": AGM/vellion battery charge program, IU1oU2 characteristic curve: Designed to charge AGM batteries (absorbing glass fiber) sealed and hermetic to gases in lead fleece technology, which have a particularly high U1 level Coordinated waiting times for full load and then a moderate level of U2 for slow load (plate and round cell technology).
• 4 "UNIVERSAL": Lead-Acid/Hummit Battery Charge Program/AGM, IU1oU2 feature curve: Universal program to load and maintain the load of acid batteries in vehicles (mobile/stationary).With a medium U1 level, it still offers short load times, a good load factor and a good mix of acids for standard batteries open and sealed, low maintenance, non-maintenance, transmission, lighting, solar and heavy service, as well as AGM. batteries with a normal U1 level.
• Li "LiFePO4": Lithium Battery Charge Program, IU1oU2 feature: Charging program adapted to Lithium Lithium Battery LiFePO4 with its own BMS and protection circuit prescribed or integrated.
• SR 300-24 can be loaded with charging programs 1, 2, 3 and 4
• 4 "UNIVERSAL": Lead-Acid/Hummit Battery Charge Program/AGM, IU1oU2 feature curve: Universal program to load and maintain the load of acid batteries in vehicles (mobile/stationary).With a medium U1 level, it still offers short load times, a good load factor and a good mix of acids for standard batteries open and sealed, low maintenance, non-maintenance, transmission, lighting, solar and heavy service, as well as AGM. batteries with a normal U1 level.
