3.3 Ripple And Noise:
Ripple and noise levels are measured at 20MHz bandwidth limit with parallel
capacitors (10uF and 0.1uF) connecting across the output of power supply.
Voltage
12Vdc
Ripple And Noise (Max.)
120mVp-p
3.4 Turn On Delay
During turn on and turn off, no output voltage shall exceed its nominal voltage by
more than 10% and no output shall change its polarity with respect to its return
line. All outputs shall reach their steady state values within 3 seconds of turn on.
3.5 Hold Up Time
10 ms minimum at 115Vac/60Hz input at maximum load, and 20 ms minimum at
230Vac/50Hz input at maximum load.
3.6 Output Transient Response
The power supply shall maintain output transient response time within 800mV
with a loading current change from 20% to 80% of maximum current and 0.5A/μs
rise up /down test at end of output terminal.
3.7 Efficiency:
77.7% minimum at input (115Vac to 230Vac) and rated output Load.
International Efficiency Level V
3.8 Output connector specification:
Please see our website www.gpelectronics.com
3.9 Hazardous Substances
The components and materials used shall be compliant with EU Directive
2003/95/EC “RoHS”
4. PROTECTION REQUIREMENT:
4.1 Over-Voltage Protection
Over-voltage protection shall be included in the adaptor circuit. A single
component failure must not cause an over voltage.
4.2 Over-Current Protection
The adaptor must have a current limiting function on the output voltage. In
overload mode, the output must drop to a low voltage.
4.3 Short-Circuit Protection
The adaptor must withstand a continuous short circuit on the output without
damage.
