DTA100A-1Y240H Min. 90VAC 47Hz - Typical 115/230VAC 50/60Hz 85% 0.9 Max. 264VAC 2.5A 63Hz 150A - Condition 90VAC 50Hz 230VAC Cold Start 115VAC at full load at full load ● Average efficiency over 87% with 25%, 50%, 75%, 100% load at 115/230VAC. ● No load input < 0.5W. OUTPUT SPECIFICATIONS 2.1 STATIC DC LOAD, RIPPLE & NOISE Nominal Voltage Total Regulation +24VDC +5%, -2% NOTE: Output Current Min. Max. 0A 4.17A Ripple & Noise 480mVp-p ● 20MHz bandwidth ripple & noise is measured by using a 0.1µF C.C. and a 10µF/50V E.C. bypassed at the output connector. ● Regulation shows the percentage of the absolute value of the nominal output voltage. ● Total maximum output power is 100W. 2.2 HOLD UP TIME The power supply unit should maintain its proper output voltage within voltage specifications for at least 16 milliseconds after losing input power under the condition of typical input with full loading. 2.3 OVERSHOOT AT TURN-ON/TURN-OFF Any overshoots during turn-on/turn-off should be less than ±5% of the nominal output voltage. No voltage of opposite polarity should be present on any output during turn-on or turn-off. 3. PROTECTION 3.1 OVER VOLTAGE PROTECTION If any over voltage occurs, the power supply should latch off before any output exceeds its limit shown in the table below. Nominal Voltage +24VDC Over Voltage Range From To +26.4VDC +31.2VDC 3.2 SHORT CIRCUIT PROTECTION Short circuit occurrence on the output should not cause any damage to the power supply but should shut down the power supply. The power supply will automatically recover after the short circuit condition is removed. (888) 597-WALL www.wallindustries.com Page 3 of 6 TECHNICAL DATASHEET Rev. A DTA100A-1Y240H 3.3 OVER LOAD PROTECTION Over load protection will come into effect when overloading reaches 110%~160% max. load. The power supply will automatically recover after the over load condition is removed. 4.
