Overview
The BV302S18015 is a power transformer from the Zettler Magnetics BV series, designed for encapsulated through-hole mounting. It features a single primary winding rated for 230VAC input and a single secondary winding providing 18VAC output at a maximum current of 83mA. The unit has a power rating of 1.5VA and utilizes an EI30 laminated core structure. Physical dimensions are specified as 32.8mm in length, 27.8mm in width, with a case height of 24.5mm. This component is intended for general power conversion applications requiring reliable isolation.
Feature Summary
- Encapsulated construction for environmental protection
- Through-hole mounting for PCB integration
- Single primary to single secondary voltage transformation
Applications
- LED lighting systems
- Electric metering devices
- Motor controls
- Thermostats
Procurement Notes
Verify the specific part number BV302S18015 against official manufacturer documentation to confirm electrical ratings and physical dimensions. Ensure compatibility with target PCB layouts regarding through-hole spacing and encapsulation height constraints. Cross-reference datasheets for insulation class and safety certifications required by the final application environment.
Selection Notes
Select this component when a compact, encapsulated transformer is needed for low-power AC-to-AC conversion. The 1.5VA rating suits applications like meters or thermostats. Verify that the 230V primary matches the supply voltage and that the 18V secondary meets load requirements. Consider the EI30 core size for spatial limitations on the assembly board.
Part Context
This transformer belongs to the BV series of encapsulated power transformers manufactured by Zettler Magnetics. The series is characterized by compact designs suitable for various control and sensing applications. The BV302S18015 specifically denotes the 1.5VA variant with 230V input and 18V output capabilities within this product line.
Replacement Considerations
Check for direct substitutes within the BV series offering identical 1.5VA ratings and 230V/18V specifications. Ensure any replacement maintains the same EI30 core size and encapsulation dimensions to fit existing mechanical constraints.
