CL2-5.0R-12

Overview

The CL2-5.0R-12 is a board-mount power transformer manufactured by Signal Transformer, operating at 50/60 Hz with a laminated core construction. It features dual primary windings rated for 115 VAC and 230 VAC input voltages. The secondary side provides a single 12 V output with a maximum current rating of 420 mA. The unit has a power rating of 5 VA and includes a high potential insulation capability of 4000 Vrms. Designed for Class 2 applications, it utilizes through-hole mounting for secure PCB integration.

Feature Summary

• Dual primary winding configuration supporting both 115 VAC and 230 VAC input standards
• High potential insulation rating of 4000 Vrms for enhanced electrical safety
• Class 2 compliant design suitable for limited energy circuits
• Laminated core construction optimized for 50/60 Hz operation

Applications

• Low-power electronic equipment requiring isolated DC supplies
• Control panels utilizing Class 2 power sources
• Industrial instrumentation with strict isolation requirements
• Consumer electronics adapters and power modules

Procurement Notes

Verify the specific manufacturer designation, as Signal Transformer products are often distributed under the Bel Signal Transformer brand name. Confirm that the 420 mA secondary current rating aligns with your circuit's load requirements. Ensure the PCB layout accommodates the through-hole pin spacing and physical dimensions specified in the official datasheet to prevent mechanical stress during assembly.

Selection Notes

Select this component when a compact, low-power transformer is needed for universal voltage inputs. The 5 VA rating limits its use to small signal or control circuits rather than high-power loads. Consider the 4000 Vrms isolation if safety regulations require significant separation between line voltage and low-voltage secondary circuits. Verify that the 12 V output matches the downstream rectification or regulation stage.

Part Context

This model belongs to the CL2 series of laminated power transformers designed for board-mount applications. The series is characterized by its compliance with Class 2 energy limitations, making it suitable for applications where hazardous energy levels must be avoided. The product line typically offers various voltage configurations while maintaining consistent physical footprints for design flexibility.

Replacement Considerations

Cross-reference part numbers such as 14A-5.0R-12 for similar specifications from the same manufacturer family. Ensure any substitute maintains the 5 VA power rating and 12 V secondary output. Verify that replacement units also support dual primary voltages and meet the required 4000 Vrms isolation standard.
