SDA-D2000A 12V Standalone Power Conversion Unit
Brief Introduction
SDA-D2000A is a cost-effective power conversion device manufactured by our Foshan based factory Sunchonglic. This 12 volt inverter adopts mature modified sine wave circuit design, which can change the direct current stored in solar storage batteries into standard alternating current that matches most household electrical appliances. Both 50 hertz and 60 hertz output frequencies are available, so it can adapt to different power standards of various countries worldwide. With stable output performance, it can work continuously for a long time, becoming a common choice for small off-grid solar systems and mobile power scenarios.
Core Design Advantages
1. Intelligent multi-protection system for stable operation
This power converter is equipped with an independent control chip that provides complete protection mechanisms. It supports battery reverse connection protection, under-voltage alarm and automatic power-off, over-voltage protection, circuit short-circuit protection, overload protection and high-temperature protection. Once abnormal working conditions are detected, the unit will stop output immediately to prevent damage to itself and connected devices. An internal replaceable fuse is installed, which greatly reduces later maintenance costs for distributors and end users.
2. Multi-port layout to meet various power demands
The unit is fitted with two universal standard sockets, which can supply power to two electrical devices at the same time. In addition, a dedicated USB port is reserved on the panel, which can charge mobile phones, wireless routers and other small electronic devices directly, without extra adapters. The layout is reasonable and meets daily power usage habits.
3. Visual LED monitoring panel
A high-brightness LED digital panel is installed on the front of the inverter, which can show real-time battery input voltage clearly. Users can check battery power status and inverter running condition at a glance, which makes daily use and maintenance more convenient.
4. Efficient heat dissipation structure and low energy consumption
It adopts a combined heat dissipation structure of aluminum alloy shell plus automatic temperature-controlled cooling fan. The fan will start working automatically when the internal temperature rises, and stop running when temperature drops, which reduces unnecessary energy waste and working noise. Its no-load power consumption is very low, and the overall energy conversion rate exceeds 85%, which helps to extend the service time of solar batteries.
