Turn-on and turn-off overshoot should not exceed 5% over nominal voltage. Measuring at 230 V and full load 12 V model: 80% All other models: 82% At 120 VAC At 120 VAC and 80% of rated maximim load 20 Output user adjustable +/- 5% Designated as RSW on the CN3. Requires a low signal to inhibit output. Designated as RS+ and RS- on the CN3. Total voltage compensation for cable losses with respect to the main output. Green - the power supply is operating normally. Orange - when any protection occurs or RSW is low. Designated as PG on the CN3. This signal goes high 100-500 mS after the output reaches regulation. It goes low at least 1 mS before loss of regulation. Designated as CSH on the CN3. Connected with parallel units for forced current sharing and accuracy with up to 4 parallel units within 10% at full load. Designated as CMN on the CN3. CMN is a 0.5 V to 3 VDC output voltage to represent 1 to 100% output current. Measured at output power connector (see chart above) * Output is fully isolated * Ripple and noise is measured from 10 KHz to 20 MHz at output terminals with a 0.1 F ceramic capacitor and a 10 F electrolytic capacitor in parallel.

A blown fuse indicates permanent damage to the power supply serviceble by factory only. Input voltage protection Power supply shut down when the ac input is under 80 VAC. When ac line reappears over 86 +/- 5 VAC, the power supply starts automatically. Overpower protection Current limiting starts at 110-140% of the rated output current and recovers automatically. Short circuit protection Short circuit can be continuous and recovers automatically. Overvoltage protection Output is protected agaist overvoltage. Unit shuts down and latches when voltage at output terminals exceeds 130% AC input needs Over temp. protection to be reset to restart the power supply. Power supply shuts down when temperature is in excess of 85 C. Auto recovery.
