Chuo Electric E189301 105 UN-10 Transformer 300VA 50 60Hz

The CHUO ELECTRIC E189301 105 UN-10 transformer is a 300 VA power transformer rated for 50/60 Hz operation, identified by the E189301 model number and the UN-10 designation. This industrial-grade unit from CHUO ELECTRIC provides a robust mid-range rating suitable for electrical installations that require a reliable transformer to power auxiliary circuits or interface equipment with higher voltage sources. The 50/60 Hz compatibility makes it adaptable to regions with different mains frequencies, while the 300 VA rating indicates it can deliver up to 0.3 kVA of apparent power within its operating limits. Exact details of the windings—including primary and secondary voltages and configuration—depend on the specific installation, so verify the winding specifications before wiring. When planning integration, confirm your equipment’s voltage and current requirements align with the transformer’s capabilities and ensure the unit physically fits within your enclosure or rack per the supplier’s datasheet.
