  "text": "(1) From 1 July 2021, VSDs must meet the following requirements.\n(2) The power losses of VSDs rated for operating with motors with a rated output power equal to or above 0.12 kW and equal to or below 1,000 kW must not exceed the maximum power losses corresponding to the IE2 efficiency level.\n(3) Energy efficiency for VSDs, expressed in International Energy efficiency classes (IE), is determined based on the power losses as follows—\n(a) the maximum power losses of the IE2 class are 25 per cent lower than the reference value referred to in Table 29;\n(b) where the apparent output power of a VSD is between two values in Table 29, the higher power loss value and the lower value of the test load displacement factor must be used for the IE class determination; and\n(c) losses are determined in accordance with Schedule 17.\nTable 29\nReference VSD losses and test load displacement factor for the IE class determination of VSDs\nApparent output power of VSD (kVA)\nRated power of motor (kW) (indicative)\nReference power losses (kW), at 90 per cent rated motor stator frequency and 100 per cent rated torque-producing current\nTest load displacement factor cos phi (+/- 0.08)\n0.278\n0.12\n0.100\n0.73\n0.381\n0.18\n0.104\n0.73\n0.500\n0.25\n0.109\n0.73\n0.697\n0.37\n0.117\n0.73\n0.977\n0.55\n0.129\n0.73\n1.29\n0.75\n0.142\n0.79\n1.71\n1.1\n0.163\n0.79\n2,29\n1.5\n0.188\n0.79\n3.3\n2.2\n0.237\n0.79\n4.44\n3\n0.299\n0.79\n5.85\n4\n0.374\n0.79\n7.94\n5.5\n0.477\n0.85\n9.95\n7.5\n0.581\n0.85\n14.4\n11\n0.781\n0.85\n19.5\n15\n1.01\n0.85\n23.9\n18.5\n1.21\n0.85\n28.3\n22\n1.41\n0.85\n38.2\n30\n1.86\n0.85\n47\n37\n2.25\n0.85\n56.9\n45\n2.70\n0.86\n68.4\n55\n3.24\n0.86\n92.8\n75\n4.35\n0.86\n111\n90\n5.17\n0.86\n135\n110\n5.55\n0.86\n162\n132\n6.65\n0.86\n196\n160\n8.02\n0.86\n245\n200\n10.0\n0.87\n302\n250\n12.4\n0.87\n381\n315\n15.6\n0.87\n429\n355\n17.5\n0.87\n483\n400\n19.8\n0.87\n604\n500\n24.7\n0.87\n677\n560\n27.6\n0.87\n761\n630\n31.1\n0.87\n858\n710\n35.0\n0.87\n967\n800\n39.4\n0.87\n1,088\n900\n44.3\n0.87\n1,209\n1,000\n49.3\n0.87",
