Key benefits Reliable DC from transformer output: converts transformer AC to DC where the no-load DC voltage = AC input × 1.42, so you can predict the unloaded DC level from your transformer. Built-in protection for system safety and uptime: includes overload, short-circuit, and over‑temperature protection to reduce risk of damage and downtime. Clean signal and stable performance: using original manufacturer accessories preserves safety, component quality, and a better overall signal‑to‑noise ratio for sensitive equipment. What this unit does (function and performance) Converts transformer secondary AC into DC; the DC output voltage and available current depend on the transformer's secondary output and the connected load. No-load DC voltage = AC input × 1.42 (use this to estimate open-circuit DC voltage). Wide input voltage range supports flexible installations while the three-tier protection system keeps the module and connected devices safe. Compatibility and installation notes Compatible with standard transformer outputs; ensure the transformer secondary matches the intended DC output after rectification (use the no‑load formula above to check). AC input voltage should not exceed 25 V. If you must use a higher AC input, a higher-voltage capacitor is required to maintain safe operation. Use original accessories supplied by the manufacturer to guarantee safety, correct fit, and the intended signal‑to‑noise performance of the complete system. Practical applications (examples) Audio systems and preamplifiers: provides clean DC with minimized noise when original parts are used, improving audio fidelity. Bench power supplies and test equipment: predictable no-load DC and protection features make it suitable for prototyping and lab use. Industrial control circuits and small automation tasks: wide input range and protective features help maintain operation in variable environments. Key attributes at a glance Function: Transformer-rectifier DC output (voltage/current depend on transformer and load) Voltage behavior: No-load DC = AC input × 1.42 Protections: Overload, short circuit, over temperature Compatibility: Works with transformer secondaries; use original accessories for best SNR and safety Important limit: AC input must not exceed 25 V unless a higher-voltage capacitor is installed If you need predictable DC from a transformer with built‑in protections and low noise when used with the original accessories, this unit delivers a practical, safe solution.
