1 Combined output power of main output, fan supply and standby supply shall not exceed max. power rating

2 Standby output voltage 5 V/ 1.5 A (convection) / 2 A (420LFM) with tolerance including set point accuracy, line and load regulation is

+/-10%. Ripple and noise is less than 5%.

3 Fan supply output voltage 12 V / 500 mA with tolerance including set point accuracy, line and load regulation is +/-30% and needs min.

1% load on main output to be within regulation band. Ripple and noise is less than 10%.

4 Ripple is peak to peak with 20 MHz bandwidth and 10 µF (Tantalum capacitor) in parallel with a 0.1 µF capacitor at rated line voltage

and load ranges. Please contact factory/ sales representative for minimum load required for ripple to be within specification.
