Case overload protected CCC Certificate 115 - 130% of peak rating Overvoltage protection: 20 - 35% above nominal output ety tureNTS350 Series Data Sheet Logic Control Power failure TTL logic signal goes high 100 - 500 msec after main output. It goes low at least 4 msec before loss of regulation Remote on/off Requires an external contact closure to inhibit outputs DC OK TTL logic goes high after the output is in regulation. It goes low when there is loss of regulation. Remote sense Compensates for 0.5 V lead drop min. Will operate without remote sense connected. Reverse connection protected. Environmental Specifications Operating temperature: 0 to 50 C ambient derate each output as 2.5% per degree from 50 to 70 C. Storage temperature: -40 C to +85 C Electromagnetic susceptibility: Designed to meet EN61000-4 -2, -3, -4, -5, -6, -8, -11 Level 3 Humidity: Operating non-condensing 10% to 90% RH Three orthogonal axes, sweep at Vibration: 1 oct/min, 5 min. dwell at four major resonances. 2 G peak 8 Hz to 500 Hz, operational MTBF demonstrated: 1M hours at full load and 25 C ambient conditions Ordering Information Maximum Load Maximum Load Ripple 1 2 Model Number Output Voltage Minimum Load with Convection with 30CFM Peak Load Regulation 3 P/P (PARD) Cooling Forced Air NTS353 12 V 0 A 16.6 A 29.2 A 33 A 2% 120 mV NTS355 24 V 0 A 8.3 A 14.6 A 16.5 A 2% 240 mV NTS358 48 V 0 A 4.2 A 7.3 A 8.2 A 2% 480 mV NTS359 54 V 0 A 3.7 A 6.5 A 7.4 A 2% 540 mV 1.
