Myrra Electronic Transformer, Switching Power Supply

Series 47000 Two Outputs, Common & Isolated 3 to 5W Regulated

ELECTRICAL SPECIFICATIONS

Input voltage range: 85 to 265 Volts AC, 85 to 370 Volts DC
Input frequency 47 to 63 Hz
Output voltage accuracy : see table for 10 to 100% rated load of each output (includes line and load variations)
No load input power <200mW
Energy consumption and efficiency: Meets requirements of Energy Star or EC Code of Conduct
The 2 outputs share a common 0v reference. This enables closer coupling and a better cross-regulation of the outputs
