Model-Specific DC Output

Complete model OWA-90U-30
Nominal DC output 30 V
Rated output current 3 A
Catalogue-rated output power 90 W
Ripple and noise, maximum 200 mVp-p; see measurement conditions.
Voltage tolerance ±3.0%, including set-up, line and load regulation.
Line regulation ±0.5%.
Load regulation ±0.5%.
Constant-current region 18–30 V, as specified for this complete model.
Set-up / rise time 500 / 80 ms at 230 VAC; 500 / 80 ms at 115 VAC, measured at 95% load.
Hold-up time, typical 16 ms at full load, at both 115 and 230 VAC.

For an LED module with its own DC/DC driver, the adapter normally operates in the constant-voltage region. Direct LED loading can use the specified 18–30 V constant-current region. Match the load and forward-voltage range to the complete system; operation below the constant-current region may enter hiccup protection.

The efficiency-versus-load curves in this family section use the 48 V model as their example. They are not an efficiency guarantee for every output voltage or load.
