TK8201A and TK8201 support inputs up to 150 V, with respective ratings of 21 A \/ 200 W and 42 A \/ 400 W. TK8201HA and TK8201H support inputs up to 500 V and 15 A, with respective power ratings of 200 W and 400 W.\u003c\/p\u003e\n\u003cp\u003eChoose TK8201A or TK8201 for inputs up to 150 V, and TK8201HA or TK8201H for inputs up to 500 V. Within each voltage family, the models provide 200 W or 400 W loading. Dynamic tests switch between two current levels. List mode combines loading steps, while battery mode discharges with voltage cutoff and capacity display.\u003c\/p\u003e\n\u003ch3\u003eModel comparison and specifications\u003c\/h3\u003e\n\u003cdiv
