Low-Frequency Transformer
CX-6640-FY05 230V to 28V/20V Dual Output Low Frequency Transformer with Mounting Bracket & Connectors for Industrial & Commercial Use
Key Features
✅ Dual-Output Power Conversion: Delivers two independent AC outputs (28V 2.1A and 20V 300mA), eliminating the need for multiple transformers in multi-voltage systems.
✅ Class B (130°C) High-Temperature Insulation: Built with heat-resistant materials to withstand demanding operating conditions, preventing overheating and ensuring long-term durability.
✅ Pre-Wired Connectors & Color-Coded Leads: Red primary leads (230V input), yellow secondary leads (28V output), and blue secondary leads (20V output) with pre-attached connectors enable quick, error-free installation.
✅ Low Noise EI Core Design: Laminated silicon steel core minimizes hum and energy loss, ensuring efficient, quiet operation even under continuous full-load conditions.
✅ Rugged Mounting Bracket: Heavy-duty metal bracket with pre-drilled holes provides secure chassis mounting, suitable for both indoor and semi-outdoor applications.
