OverviewĀ
Safely bridge the gap between high-voltage power networks and low-voltage control systems with the UENPO High-Voltage Isolated DC-DC Step-Down Power Supply Module. Engineered for continuous industrial duty, this converter accepts an input range from 75 VĀ up to 150 V DC and converts it to a highly stable 12 V DCĀ rail capable of delivering up to 5AĀ (60 WĀ of clean current. Featuring true galvanic isolation between the input and output circuits, this module guarantees that a catastrophic spike on your primary high-voltage side will never migrate down to fry your sensitive microcontrollers, PLCs, or telemetry sensors.
Key FeaturesĀ
True Galvanic Circuit Isolation: Provides complete electrical separation between the high-voltage input and low-voltage output stages, eliminating ground loops and suppressing massive electrical noise.
Ultra-Wide High-Voltage Input: Rugged internal topology handles wide voltage fluctuations ($75\text{V} – 150\text{V DC}$), making it ideal for solar strings, telecom backup banks, and EV platforms.
Heavy-Duty 60W Output: Continuously delivers up to 5 Amps at 12V DC, easily powering heavy inductive loads like industrial relays, solenoid valves, actuators, and chassis cooling fans.
Rugged Industrial Packaging: Housed in a compact, vibration-resistant casing with an integrated aluminum heatsink backplane for excellent passive thermal dissipation.
Comprehensive Fault Shielding: Complete safety layer featuring over-current limiting, over-temperature throttling, input under-voltage lockout, and continuous short-circuit recovery.
