Notes
1 Output voltage tolerance is ±2%, drift from set point ±1%.
2 Linear derating to 75% x P at 70°C (158 °F) (2.5% per K above 60°C [140 °F]).

3 Boost Wattage is continuously available for T
4 Hazardous (classified) Location approvals: All units: CID2 (Class I Division 2 Groups A,B,C,D; T4); units 2, 4, 6, 8, 11, 13, 14, 15: ATEX (II 3G Ex nA IIC T4 Gc) and IECEx (Ex nA IIC T4 Gc).
5 960 W supplies require additional power derating for low input voltage: AC < 100 V ac: 1% / V; DC < 120 V dc: 0.5% / V.
6 Output voltage is 0.2 V less than input voltage.
7 Output has varistor protection against static surge voltages > 32 V.
8 Items 6, 8, 11, 13 have input over-voltage protection to PE by a varistor in series with a gas discharge tube (GDT). The GDT must be removed for a surge test that exceeds 1500 V peak, or else
its conduction current will indicate a test failure. When the GDT is removed, the power supplies are protected by surge capacitors to pass the test. In normal operation, if the GDT is triggered into
its conducting state by a voltage surge, it will be turned off by the impedance of the varistor when the voltage to PE drops below 320 V dc.
9 At the nominal DC output voltage and above, the output has a constant power characteristic. Adjusting the DC output voltage below the nominal value puts the output into a constant current
mode. For example, for a 480W, 48V nominal, 10A supply with the output voltage adjusted to the nominal or a higher value, there is 480W available no matter what the output voltage is, up to 60°
C (140 °F). When the output voltage is adjusted to 40V, only 10A is available (40x10 = 400W). At 40°C (104 °F) or less, the standard boost current is still available. So, there is 624/48 = 13A
available (40x13 = 520W) up to 40°C (104 °F).
