LKB4820-L-2301201

Power Transformers Overview

The LKB4820-L-2301201 is a laminated core power transformer manufactured by PowerUC Electronics. It features a single primary winding rated for 230V input and a secondary output of 12V at a maximum current of 1A, delivering 12VA of power. The unit utilizes vacuum epoxy encapsulation for insulation and mechanical protection. Key electrical specifications include a primary-to-secondary isolation voltage of 3500Vrms (3.5KV) tested for 1 minute with a leakage current limit of 5mA. The device supports frequencies of 50Hz and operates within an ambient temperature range of -30°C to +40°C.

Power Transformers Feature Summary

• Vacuum epoxy sealing ensures high electrical strength and environmental resistance
• Provides safety isolation between primary and secondary circuits
• Utilizes high-quality H18 silicon steel for the laminated core
• Designed for long-term reliability with a specified lifespan of 20 years

Power Transformers Applications

• Panel mount industrial control systems
• Safety isolation in low-voltage power supplies
• Equipment requiring 12V DC or AC auxiliary power
• General purpose isolation transformers

Power Transformers Procurement Notes

Verify the specific suffix code against official PowerUC Electronics documentation to confirm exact pinout and mounting configuration. Ensure the application environment stays within the stated -30°C to +40°C operating range. Confirm that the required isolation voltage meets the 3500Vrms standard for your safety compliance needs. Cross-reference the 12VA rating with actual load requirements to prevent overload conditions during operation.

Power Transformers Selection Notes

Select this model when a robust, panel-mountable isolation transformer is required for 230V input applications. The 12VA capacity suits low-power control circuits rather than high-load drives. Consider the physical dimensions and plate mounting style if space constraints exist. Verify that the 50Hz frequency requirement aligns with the local power grid standards before integration into the final assembly design.

Power Transformers Part Context
