Ripple & Noise :
The power supply shall not exceed 250mVrms on the indicated voltage for 60Hz or 50Hz
ripple, switching frequency ripple and noise dynamic load variations measured with a
20MHz bandwidth. Ripple & noise are measured at the end of output cables to which are
added a 0.1uf ceramic capacitor and a 10uF electrolytic capacitor.
Leakage Current:
0.75mA
Over Voltage Protection :
27V max.(do not test with external DC source).
Shutdown voltage protection:
10V max.
