## Key Features

• Split bobbin design reduces capacitive coupling between windings
• Single center-tapped secondary winding for dual-polarity operation
• Compact chassis-mount footprint
• UL 506 / UL 5085-1 recognized (File # E63829)
• CSA certified to C22.2 #66.1 (File # 221070)
• Meets UL 5085 safety standards

## Typical Applications

General electronic equipment requiring regulated low-voltage DC or AC power supplies, audio amplifier bias networks, control circuit power, and instrumentation support systems.

## Compatibility & Integration

The 241-5-2520 integrates into applications demanding 20 V output at up to 600 mA secondary current from standard 115 V AC mains. Center-tapped secondary configuration permits either single-ended or split-rail supply design. Mounting provisions accommodate standard chassis installation with solder lug or quick-connect terminal connectivity.
