12J70 A series of modern and efficient PWM regulators. Not only the appearance testifies to the professional nature of the devices offered here. Most budget (cheap) regulators do not even have a heat sink to dissipate the heat generated. Higher temperatures mean higher losses and worse efficiency. In practice, such devices overheat, parameters calibrate and easily damage batteries. Why save PLN 100 on the regulator when you can damage the battery worth many times more? A decent regulator cannot cost less than PLN 100. Cheaper devices are toys. If you value reliability and durability, do not look for other devices. Here you have found what you need. Display showing the operating parameters of the device (voltage, current, temperature, etc.), two USB ports for charging portable devices, two 12V outputs for powering selected receivers. Large cable terminals allow you to connect wires with a cross-section of up to 25mm2. The dimensions and weight of the device also say a lot about the quality. No one here saved on materials. It has an LCD display, battery charging functions based on the PWM algorithm, all necessary protections. Adapted to work with 12V and 24V batteries (automatic detection). The control parameters can be adapted to different battery operating parameters, which makes it easy to adapt to different types of batteries. Overcurrent protection, short-circuit protection, automatic return and restoration of operation. It provides solid DC charging of batteries with battery temperature compensation. Specification: Model: PVSC30A / PVSC50A / PVSC70A Voltage: 12 / 24V Current respectively: 30A/50A/70A Voltage of Max panels: 50V
