MD50A / MD100A / MD200A 1600V Antireverse Diode Module Key benefits Prevents reverse current and protects connected sources and batteries with an integrated antireverse charging diode. Speeds up charging operations by ensuring current flows only in the intended direction, reducing charging time and improving system efficiency. Built for longterm reliability in power systems and industrial applications where reverse feeding or discharge would cause damage or downtime. What it does Antireverse diode module designed to allow forward charging while blocking reverse current that can drain batteries or backfeed sensitive equipment. Suitable for use in systems requiring robust DC protection and reliable rectification behavior. Compatibility and performance Models: MD50A, MD100A, MD200A (including the 1600V version). Voltage ratings available from 600V up to 4000V to match different system requirements, with the 1600V model included in the lineup. Constructed from strong, durable materials to withstand industrial operating conditions and deliver consistent performance over time. Typical applications Solar photovoltaic systems: install in PV panel arrays, DC cabinets or combiner boxes to block reverse current at night and protect string/battery systems. Battery systems and rectified power supplies: use in battery charging/discharging installations and DC supply units to prevent battery discharge and protect rectifiers. Industrial drives and reactive power equipment: suitable for motor soft starters, frequency conversion boxes, static reactive power compensation units, and wind engine DC excitation to protect DC circuits from backfeed and ensure stable operation. Practical use scenarios Solar farm combiner box: the module prevents nighttime backflow into PV strings, protecting panels and reducing stray discharge to batteries. Backup battery bank: in a DC backup or UPS battery string, the diode module blocks reverse discharge when the main supply returns, protecting the battery and the charging circuit. Wind turbine DC excitation: used on the turbine's excitation rectifier to prevent reverse current during system transitions or faults, improving system safety and reliability. Why choose this module Direct protection: specifically designed to stop reverse current and protect connected DC equipment. Versatile voltage options: available across a wide voltage range to fit different system designs, with a dedicated 1600V model in the product family. Durable construction: built to handle demanding electrical environments, supporting longer service life and reduced maintenance.
