Electronic transformers TWO ISOLATED OUTPUTS 3 to 5W
Electronic transformers TWO ISOLATED OUTPUTS 3 to 5W |
Electrical specifications
Input voltage range
- 85 to 265 Volts AC
- 85 to 370 Volts DC
- Input Frequency 47 to 440 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 efficienc: Meets reguirements of Energy Star or EC Code of Conduct.
The 2 isolated output - Output 1 only is regulated and should provide the higher power. |
